The effects of tillage and crop rotation on soil physico-chemical properties, soil organic carbon (SOC) and N have been studied widely in long and short-term experiments. However, their effects on nutrient levels and fertility losses have not been extensively studied in Mediterranean soils. We determined SOC, N, P, K, Fe, Mn, Cu and Zn distribution in the soil profile and in plant uptake, on a Calciortidic Haploxeralf in Spain. Three tillage systems [CT, conventional tillage (mouldboard plow); MT, minimum tillage and NT, no tillage] and three crop rotations [BB, continuous barley (Hordeum vulgare v. Tipper), FB, fallow-barley and VB, vetch (Vicia sativa v. Muza)-barley] were compared. SOC and N were higher for CT than for MT and NT in the first year, but higher for NT and MT than CT in the next years. In the 0-15 cm depth, SOC and N in NT also became higher than in MT for the fourth crop season. In the 15-30 depths, NT and MT had also higher SOC than CT since the second year. However, NT had only higher N than MT after three crop seasons. The increase in SOC was 75% for NT and MT while CT had a decrease of 17% in the 0-15 cm layer. The increase in N was 154% for NT, 108% for MT and 30% for CT in the upper 15 cm. NT had higher P, K and Cu than MT and higher P, K, Fe, Mn, Cu and Zn than CT in the upper layers due to the higher SOC level and to the fact that these systems maintain surface-applied K and P fertilizer. On the other hand, neither SOC nor N were affected by crop rotation. Tillage and rotation interactions were not significant for SOC, N and, in general, nutrient levels in the different soil depths. In general, the main factor that affected SOC, N and nutrients was tillage, which had reduced influence with depth. Highest yield was for CT-FB and CT-VB, but not different from NT-FB and NT-VB, meanwhile highest nutrient levels were obtained for interactions that included NT. These results suggest that NT, and to a lesser extend MT, preserved SOC and nutrient levels in the upper layers and, with NT-VB and NT-FB interaction, could also obtain high yields and keep soil fertility in the upper depths during the first 4 years. \u00a9 2006 Elsevier B.V.

Theory and data suggest that N capture from pulses should depend on plant growth rate and availability of other limiting resources. Theory also predicts trade-offs in plant stress tolerance and ability to capture N from different size pulses. We injected K15NO3, to simulate small and large N pulses at three different times during the growing season into soil around the co-dominant Great Basin species Sarcobatus vermiculatus, Chrysothamnus nauseosus ssp. consimilis, and Distichlis spicata. Soils were amended with water and P in a partial factorial design. As predicted, all study species showed a comparable decline in N capture from large pulses through the season as growth rates slowed. Surprisingly, however, water and P availability differentially influenced the ability of these species to capture N from pulses. Distichlis N capture increased up to tenfold with water addition while Chrysothamnus N capture increased up to threefold with P addition. Sarcobatus N capture was not affected by water or P availability. Opposite to our prediction, Sarcobatus, the most stress tolerant species, captured less N from small pulses but more N from large pulses relative to the other species. These observations suggest that variation in N pulse timing and size can interact with variable soil water and P supply to determine how N is partitioned among co-existing Great Basin species.", "keywords": ["2.

The experiment was set-up according to an incomplete, optimal design, with three factors at five levels and 12 treatments, including a control with two replications. Statistical analyses using multiple regression models showed that the partial N, P and K balances were strongly influenced by annual variations in the amounts of soil water at seeding (SWS) and growing season rainfall (GSR). Most treatments had positive P but negative N and K balances. Cumulative P and K balances were reflected in extractable soil P (P-Olsen) and K (exchangeable K), but the weak relationships indicated that the sorption of P and buffering of K were strong. Cumulative balances of effective organic carbon (C) were weakly related to soil organic C (SOC) content after 12\u00a0years. Negative C balances were related to decreases in SOC, but positive C balances were not translated into increases in SOC. The analysis of nutrient balances and soil fertility indices revealed that nutrient inputs in most treatments were far from balanced.

However, in many places its intensive use has become a burden to the environment, and legislation has been introduced to restrict nutrient applications. In combination with changing production scenarios as a result of climate change, this means an improved understanding is needed of how low nutrient availability and climatic stress factors affect yields and yield stability.We examined the long-term effects mineral and organic fertilisation on a nutrient-depleted field, and observed large annual variations: depending on the year, average spring barley yields under unfertilised management (U) were between 17-75% lower than the reference N1/2P1/2K1/2 (60-10-60 kg ha(-1)). Yields increased up to 174% under N1P1K1 (120-20-120 kg ha(-1)), while animal manure applications at an N availability level corresponding to N-1 were between 79 and 137%. No temporal yield trends could be observed, but long-term changes of Olsen-P and exchangeable K were related to the nutrient balances (inputs-offtake) (r(2) = 0.60 and 0.59, respectively, P < 0.001).Multiple linear regression analysis was used to examine the effects of the treatments in combination with annual weather variations. The results could be split into two outcomes, 1) a general relation between yields and temperatures for the periods of early spring (P < 0.01, multiple R-2 = 0.31) and summer (P < 0.001, multiple R-2 =0.45), and 2) an interaction between temperature and nutrient applications during crop establishment, leading to a diverse response of relative yields (P < 0.001 multiple R-2 =0.64), i.e. relative yield losses under the unfertilised treatment (U) were greater in years with lower spring temperatures, and, conversely, the increased nutrient availability in the fully mineral and organically fertilised treatments could partially alleviate the negative effects.After 13 years of repeated fertilisation, inputs were suspended for a single year and only N was applied to evaluate the residual effects. Yields were significantly affected by the different fertilisation histories (P < 0.001). Likewise, apparent nitrogen recovery tended to improve with previous inputs, but the observations were highly variable.Overall, the analyses agree with the notion that brief periods of stress at a critical stage may significantly affect yields, and confirmed that management of sufficient nutrient availability is critical for maintaining high and stable yields.

However, only a few PTFs have been developed to predict soil nutrients using environmental variables and to extrapolate them to characterize spatial soil variations at a regional scale. In this study, we attempted to develop PTFs for the total nitrogen (TN), total phosphorus (TP) and total potassium (TK) concentrations in three typical pedo-climatic areas of China (Fujian Province, Jiangsu Province and Qilian Mountains) with diverse climate, terrain and soil types. A series of linear PTFs were developed to quantify the effect of terrain and climate on the predictive relations between the soil nutrients and other measured soil properties and environmental variables. In addition, digital soil mapping (DSM) based on the random forest (RF) technique was performed to test the hypothesis that the best-fit PTFs could be extrapolated, based on soil maps and environmental variables, to describe regional soil variations in the soil nutrients. The root mean square errors (RMSEs) of the best-fit PTFs for TN, TP and TK ranged from 0.21 to 0.79 g kg\u22121, 0.20 to 0.58 g kg\u22121, and 3.68 to 5.00 g kg\u22121, respectively.

PTFs provided a sound basis for database compilation if the soil properties were highly correlated. However, the extrapolation of best-fit PTFs to regional scales yielded greater errors than those produced by DSM. The comparison results reveal the limitations of PTFs and suggest that their performance could be improved by using environmental covariates or by fitting data in areas with relatively homogeneous soil landscapes.

In a species-rich poor fen (Caricetum nigrae) and a species-poor drained fen, the difference in nutrient limitation of the vegetation was assessed in a full-factorial fertilization experiment with N, P and K. The results were compared to the nutrient ratios of plant material and to chemical analysis of the topsoil. A rewetting experiment with intact sods was carried out in the glasshouse and the results are discussed in view of restoration prospects of drained and degraded peatlands. In the undrained poor fen the above-ground biomass yield was N-limited while the vegetation of the drained fen was K-limited. Experimental rewetting of intact turf samples, taken in the drained site, did not change the biomass yield or the type of nutrient limitation. It was concluded that mire systems which have been subjected to prolonged drainage are inclined to pronounced K-deficiency, probably due to washing out of potassium and harvesting the standing crop. This may hamper restoration projects in degraded peat areas where nature conservation tries to restore species-rich vegetation types with a high nature value.

However, uncertainty about how ecosystems respond to decadal changes in fire frequency makes it difficult to predict the effects of altered fire regimes on the carbon cycle; for instance, we do not fully understand the long-term effects of fire on soil carbon and nutrient storage, or whether fire-driven nutrient losses limit plant productivity. Here we analyse data from 48 sites in savanna grasslands, broadleaf forests and needleleaf forests spanning up to 65 years, during which time the frequency of fires was altered at each site. We find that frequently burned plots experienced a decline in surface soil carbon and nitrogen that was non-saturating through time, having 36 per cent (\u00b113 per cent) less carbon and 38 per cent (\u00b116 per cent) less nitrogen after 64 years than plots that were protected from fire. Fire-driven carbon and nitrogen losses were substantial in savanna grasslands and broadleaf forests, but not in temperate and boreal needleleaf forests. We also observe comparable soil carbon and nitrogen losses in an independent field dataset and in dynamic model simulations of global vegetation. The model study predicts that the long-term losses of soil nitrogen that result from more frequent burning may in turn decrease the carbon that is sequestered by net primary productivity by about 20 per cent of the total carbon that is emitted from burning biomass over the same period. Furthermore, we estimate that the effects of changes in fire frequency on ecosystem carbon storage may be 30 per cent too low if they do not include multidecadal changes in soil carbon, especially in drier savanna grasslands. Future changes in fire frequency may shift ecosystem carbon storage by changing soil carbon pools and nitrogen limitations on plant growth, altering the carbon sink capacity of frequently burning savanna grasslands and broadleaf forests.", "keywords": ["2.

In this study, we attempted to develop PTFs for the total nitrogen (TN), total phosphorus (TP) and total potassium (TK) concentrations in three typical pedo-climatic areas of China (Fujian Province, Jiangsu Province and Qilian Mountains) with diverse climate, terrain and soil types. A series of linear PTFs were developed to quantify the effect of terrain and climate on the predictive relations between the soil nutrients and other measured soil properties and environmental variables. In addition, digital soil mapping (DSM) based on the random forest (RF) technique was performed to test the hypothesis that the best-fit PTFs could be extrapolated, based on soil maps and environmental variables, to describe regional soil variations in the soil nutrients. The root mean square errors (RMSEs) of the best-fit PTFs for TN, TP and TK ranged from 0.21 to 0.79 g kg\u22121, 0.20 to 0.58 g kg\u22121, and 3.68 to 5.00 g kg\u22121, respectively.

Human activities have greatly increased the availability of biologically active forms of nutrients [e.g., nitrogen (N), phosphorous (P), potassium (K), magnesium (Mg)] in many soil ecosystems worldwide. Multi\uffe2\uff80\uff90nutrient fertilization strongly increases plant productivity but may also alter the storage of carbon (C) in soil, which represents the largest terrestrial pool of organic C. Despite this issue is important from a global change perspective, key questions remain on how the single addition of N or the combination of N with other nutrients might affect C sequestration in human\uffe2\uff80\uff90managed soils. Here, we use a 19\uffe2\uff80\uff90year old nutrient addition experiment on a permanent grassland to test for nutrient\uffe2\uff80\uff90induced effects on soil C sequestration. We show that combined NPKMg additions to permanent grassland have \uffe2\uff80\uff98constrained\uffe2\uff80\uff99 soil C sequestration to levels similar to unfertilized plots whereas the single addition of N significantly enhanced soil C stocks (N\uffe2\uff80\uff90only fertilized soils store, on average, 11\uffc2\uffa0t C\uffc2\uffa0ha\uffe2\uff88\uff921 more than unfertilized soils). These results were consistent across grazing and liming treatments suggesting that whilst multi\uffe2\uff80\uff90nutrient additions increase plant productivity, soil C sequestration is increased by N\uffe2\uff80\uff90only additions. The positive N\uffe2\uff80\uff90only effect on soil C content was not related to changes in plant species diversity or to the functional composition of the plant community. N\uffe2\uff80\uff90only fertilized grasslands show, however, increases in total root mass and the accumulation of organic matter detritus in topsoils. Finally, soils receiving any N addition (N only or N in combination with other nutrients) were associated with high N losses. Overall, our results demonstrate that nutrient fertilization remains an important global change driver of ecosystem functioning, which can strongly affect the long\uffe2\uff80\uff90term sustainability of grassland soil ecosystems (e.g., soils ability to deliver multiple ecosystem services).

Long\uffe2\uff80\uff90term elevated nitrogen (N) input from anthropogenic sources may cause soil acidification and decrease crop yield, yet the response of the belowground microbial community to long\uffe2\uff80\uff90term N input alone or in combination with phosphorus (P) and potassium (K) is poorly understood. We explored the effect of long\uffe2\uff80\uff90term N and NPK fertilization on soil bacterial diversity and community composition using meta\uffe2\uff80\uff90analysis of a global dataset. Nitrogen fertilization decreased soil pH, and increased soil organic carbon (C) and available N contents. Bacterial taxonomic diversity was decreased by N fertilization alone, but was increased by NPK fertilization. The effect of N fertilization on bacterial diversity varied with soil texture and water management, but was independent of crop type or N application rate. Changes in bacterial diversity were positively related to both soil pH and organic C content under N fertilization alone, but only to soil organic C under NPK fertilization. Microbial biomass C decreased with decreasing bacterial diversity under long\uffe2\uff80\uff90term N fertilization. Nitrogen fertilization increased the relative abundance of Proteobacteria and Actinobacteria, but reduced the abundance of Acidobacteria, consistent with the general life history strategy theory for bacteria. The positive correlation between N application rate and the relative abundance of Actinobacteria indicates that increased N availability favored the growth of Actinobacteria. This first global analysis of long\uffe2\uff80\uff90term N and NPK fertilization that differentially affects bacterial diversity and community composition provides a reference for nutrient management strategies for maintaining belowground microbial diversity in agro\uffe2\uff80\uff90ecosystems worldwide.

1.\uffe2\uff80\uff82The cycling of nutrients in litterfall is considered a key mechanism in the maintenance of tropical forest fertility but its importance has rarely been quantified experimentally.

2.\uffe2\uff80\uff82We carried out a long\uffe2\uff80\uff90term (5\uffe2\uff80\uff83years), large\uffe2\uff80\uff90scale litter manipulation experiment in lowland semi\uffe2\uff80\uff90evergreen tropical forest to determine how changes in litterfall affect forest nutrient cycling. We hypothesized that: (i) long\uffe2\uff80\uff90term litter removal would decrease the forest\uffe2\uff80\uff99s nutrient supply; (ii) litter addition would increase the forest\uffe2\uff80\uff99s nutrient supply; (iii) soil and foliar nutrient concentrations would change in response to litter manipulation and would eventually affect above\uffe2\uff80\uff90ground productivity.

3.\uffe2\uff80\uff82To test our hypotheses, we measured trunk growth, litterfall, and nutrient concentrations in live leaves, litter and soil in plots where litter was removed once a month (L\uffe2\uff88\uff92), litter was added once a month (L+) and controls (CT).

4.\uffe2\uff80\uff82After 5\uffe2\uff80\uff83years, the concentration of nitrate in the soil and soil stocks of inorganic nitrogen were higher in the L+ plots and lower in the L\uffe2\uff88\uff92 plots compared to the controls. Ammonium concentrations in the soil were also lower in the L\uffe2\uff88\uff92 plots. Nitrogen in leaves and litter and the annual nitrogen return by litter were higher in the L+ plots, while potassium return was lower in the L\uffe2\uff88\uff92 plots. Surprisingly, our treatments had little effect on phosphorus in soil, leaves or litter, even though lowland tropical forests are generally thought to be largely phosphorus limited.

5.\uffe2\uff80\uff82Trunk growth of large trees was not affected by litter manipulation but rainy season litterfall from 2003 to 2008 was 13% higher in the L+ plots compared to the controls.

6.\uffe2\uff80\uff82Synthesis. Litter removal affected forest nutrient cycling and productivity less than expected, probably because the soil at our site is moderately fertile. However, litter addition increased litterfall indicating that some limitation of forest production was removed by litter addition. We expected strong effects of litter manipulation on phosphorus cycling; instead, we found a stronger effect on nitrogen cycling. Our results suggest that litter is an important source of nutrients, in particular nitrogen, to trees in this lowland semi\uffe2\uff80\uff90evergreen tropical forest.

To explore the importance of 12 elements in litter production and decomposition, we fertilized 36 1600\uffe2\uff80\uff83m2\uffe2\uff80\uff90plots with combinations of N, P, K, or micronutrients (i.e. B, Ca, Cu, Fe, Mg, Mn, Mo, S, Zn) for 6\uffe2\uff80\uff83years in a lowland Panamanian forest.

Our results suggest tropical forests are a non\uffe2\uff80\uff90Liebig world of multiple nutrient limitations, with at least four elements shaping rates of litterfall and decomposition.

The influence of long\uffe2\uff80\uff90term chemical fertilization on soil microbial communities has been one of the frontier topics of agricultural and environmental sciences and is critical for linking soil microbial flora with soil functions. In this study, 16S rRNA gene pyrosequencing and a functional gene array, geochip 4.0, were used to investigate the shifts in microbial composition and functional gene structure in paddy soils with different fertilization treatments over a 22\uffe2\uff80\uff90year period. These included a control without fertilizers; chemical nitrogen fertilizer (N); N and phosphate (NP); N and potassium (NK); and N, P and K (NPK). Based on 16S rRNA gene data, both species evenness and key genera were affected by P fertilization. Functional gene array\uffe2\uff80\uff90based analysis revealed that long\uffe2\uff80\uff90term fertilization significantly changed the overall microbial functional structures. Chemical fertilization significantly increased the diversity and abundance of most genes involved in C, N, P and S cycling, especially for the treatments NK and NPK. Significant correlations were found among functional gene structure and abundance, related soil enzymatic activities and rice yield, suggesting that a fertilizer\uffe2\uff80\uff90induced shift in the microbial community may accelerate the nutrient turnover in soil, which in turn influenced rice growth. The effect of N fertilization on soil microbial functional genes was mitigated by the addition of P fertilizer in this P\uffe2\uff80\uff90limited paddy soil, suggesting that balanced chemical fertilization is beneficial to the soil microbial community and its functions.

Total tree biomass was greatest for red pine followed by aspen, spruce, and jack pine. Nutrient weights (N, P, K, Ca, Mg) in the trees were greatest in aspen followed generally by spruce, red pine, and jack pine. Particularly large proportions of biomass and nutrients were found in aspen bark and spruce foliage and branches. Understory biomass contributed less than 1.2% of the total organic matter in the vegetation\uffe2\uff80\uff93soil complex but contributed up to 5.0% of the nutrients.

Soil chemical properties were studied after a wildfire in stands of white spruce (Piceaglauca (Moench) Voss), black spruce (Piceamariana (Mill.) B.S.P.), paper birch (Betulapapyrifera Marsh.), and quaking aspen (Populustremuloides Michx.). Samples of the forest floor and surface 5\uffe2\uff80\uff82cm of mineral soil were collected from burned sites and unburned controls and analyzed soon after the fire. With the exception of soil pH, effects of the fire on soil chemistry differed among the four forest types. Generally, amounts of exchangeable K, Ca, and Mg did not appreciably increase in the forest floor and surface mineral soil except in heavily burned areas in white spruce and black spruce. Fire reduced amounts of N by about 50% in white spruce, aspen, and birch forest floors. In black spruce, quantities of N were slightly higher in heavily burned locations. Forest floor C:N ratios were substantially lower in heavily burned locations in white spruce and black spruce than in unburned controls. Burning did not have a marked influence on supplies of available P in the forest floor, except in heavily burned black spruce, where average amounts were 12.50\uffe2\uff80\uff82g/m2 versus only 0.46\uffe2\uff80\uff82g/m2 in the control. Burning caused more moderate gains in available P in surface mineral soils under aspen and white spruce. We concluded that fire caused marked short-term changes in soil chemistry in the four forest types. How long these changes will persist is unknown.

This study was conducted to know cropping cycles required to improve OM status in soil and to investigate the effects of medium-term tillage practices on soil properties and crop yields in Grey Terrace soil of Bangladesh under wheat-mungbean-T.amancropping system. Four different tillage practices, namely, zero tillage (ZT), minimum tillage (MT), conventional tillage (CT), and deep tillage (DT), were studied in a randomized complete block (RCB) design with four replications. Tillage practices showed positive effects on soil properties and crop yields. After four cropping cycles, the highest OM accumulation, the maximum root mass density (0\uffe2\uff80\uff9315\uffe2\uff80\uff89cm soil depth), and the improved physical and chemical properties were recorded in the conservational tillage practices. Bulk and particle densities were decreased due to tillage practices, having the highest reduction of these properties and the highest increase of porosity and field capacity in zero tillage. The highest total N, P, K, and S in their available forms were recorded in zero tillage. All tillage practices showed similar yield after four years of cropping cycles. Therefore, we conclude that zero tillage with 20% residue retention was found to be suitable for soil health and achieving optimum yield under the cropping system in Grey Terrace soil (Aeric Albaquept).

A study of the relationship between the soil Olsen P concentration and the P balance (P input minus P output) and their variations among different fertilization patterns will help to provide useful information for proper management of P fertilization. In this paper, the two investigated long-term experiments were established on black soils in the northeast region of China. Six fertilization treatments were selected: (1) unfertilized (CK); (2) nitrogen only (N); (3) nitrogen and potassium (NK); (4) nitrogen and phosphorus (NP); (5) nitrogen, phosphorus, and potassium (NPK); and (6) nitrogen, phosphorus, potassium and manure (NPKM). The results showed that the average Olsen P concentrations in the black soils at Gongzhuling and Harbin (16- and 31-year study periods, respectively), decreased by 0.49 and 0.56 mg kg-1 a-1, respectively, without P addition and increased by 3.17 and 1.78 mg kg-1 a-1, respectively, with P fertilization. The changes in soil Olsen P concentrations were significantly (P<0.05) correlated with the P balances at both sites except for the NP and NPK treatments at Gongzhuling. Under an average deficit of 100 kg ha-1 P, the soil Olsen P concentration at both sites decreased by 1.36~3.35 mg kg-1 in the treatments without P addition and increased by 4.80~16.04 mg kg-1 in the treatments with 100 kg ha-1 of P accumulation. In addition, the changes in Olsen P concentrations in the soil with 100 kg ha-1of P balance were significantly correlated with the P activation coefficient (PAC, percentage of Olsen P to total P, r=0.99, P<0.01) and soil organic matter content (r=0.91, P<0.01).

The efficiency of SOC sequestration depends on the quantity and quality of the organic matter, soil type, and climate. Little is known about the SOC sequestration efficiency of organic amendments in Vertisols. Thus, we conducted the research based on 29 years (1982-2011) of long-term fertilization experiment with a no fertilizer control and five fertilization regimes: CK (control, no fertilizer), NPK (mineral NPK fertilizers alone), NPK+1/2W (mineral NPK fertilizers combined with half the amount of wheat straw), NPK+W (mineral NPK fertilizers combined with full the amount of wheat straw), NPK+PM (mineral NPK fertilizers combined with pig manure) and NPK+CM (mineral NPK fertilizers combined cattle manure).

Moreover, the C sequestration efficiencies of wheat straw, pig manure and cattle manure were 17%, 11% and 17%, respectively.

With thawing permafrost, especially in ice-rich regions such as the Yedoma domain, vast amounts of organic carbon previously stored in deep frozen deposits are unlocked and therefore available to undergo microbial mineralization leading to potential carbon dioxide and methane emissions. Mineral elements interfere with organic carbon degradation through various processes: i) mineral protection (aggregation, adsorption, and complexation) stabilizes organic carbon and mitigates its mineralization, and ii) change in mineral nutrients availability affects microorganisms growth and metabolic activity. Despite huge efforts to assess organic carbon stocks and lability in permafrost regions, there is a lack of studies on the mineral component assessment, which we aim to close with this dataset. Here, we provide a large-scale Yedoma domain Mineral Concentrations Assessment (YMCA) dataset of never thawed (since deposition) ice-rich Yedoma permafrost and previously thawed and partly refrozen Alas deposits. We used a portable X-ray fluorescence device (pXRF) for Si, Al, Fe, Ca, K, Ti, Mn, Zn, Sr and Zr concentration measurements on 1,292 sediment samples. Portable XRF measured concentrations trueness was calibrated using standard alkaline fusion and ICP-OES measurement from a subset of 144 samples (R\u00b2 from 0.725 to 0.996). This methodology lead to the creation of the Yedoma domain Mineral Concentration Assessment (YMCA) dataset, a necessary step to estimate mineral element stocks in never thawed Yedoma and previously thawed Alas deposits. Practically, the YMCA dataset is organized as follow: (i) all site and sample properties: sample ID, type of deposit, site location, profile ID, GPS coordinates, country, lithology, unconsolidated sediment type, geological epoch, samples depth below surface level (b.s.l) or height above sea/river level (a.s.l), sediment characteristics, bulk density, gravimetric and absolute ice content, total organic carbon content; (ii) the Si, Al, Fe, Ca, K, Ti, Mn, Zn, Sr and Zr concentrations (corrected based on linear regressions) in Yedoma and Alas deposits (n=1292).", "keywords": ["Density", "Permafrost", "Profile ID", "gravimetric", "Density", " bulk", " permafrost", "Aluminium", "total", "Sample code/label", "Portable X ray fluorescence device", "Titanium", "Mineral element", "Yedoma", "Portable X-ray fluorescence device", "Description", "Number", "Lithology/composition/facies", "Sample code label", "6.

Plants and soils represent coevolving components of ecosystems, and while the effects of soils (e.g., nutrient availability) on plants have been extensively documented, the effect of plants on soils has received less attention. Furthermore there has been no systematic investigation of how plant effects vary across important ecological gradients in climate or soil age, which leaves a substantial gap in our understanding of how plant\uffe2\uff80\uff93soil systems develop. In this context, we analyzed changes in nutrient availability and elemental losses from the entire weathering zone at 35 sites arrayed across climatic and soil\uffe2\uff80\uff90age gradients on the island of Hawai\uffe2\uff80\uff98i. The sites are located on three basaltic lava flows (ages 10, 170, and 350 kyr) each of which crosses a precipitation gradient from \uffe2\uff88\uffbc500 to 2500 mm/yr. By comparing the loss of nutrient (potassium, phosphorus) and non\uffe2\uff80\uff90nutrient (e.g., sodium) rock\uffe2\uff80\uff90derived elements, we identify a climatic zone at intermediate rainfall where the retention of plant nutrients in the upper soil is most pronounced. We further show that there are several abiotic constraints on plant\uffe2\uff80\uff90driven retention of nutrients. At the dry sites (\uffe2\uff89\uffa4750 mm/yr on all three flows), plants slow the loss of nutrients, but the effect (as measured by the difference between K and Na losses) is small, perhaps because of low plant cover and productivity. At intermediate rainfall (750\uffe2\uff80\uff931400 mm/yr) but negative water balance, plants substantially enrich both nutrient cations and P relative to Na in the surface horizons, an effect that remains strong even after 350 kyr of soil development. In contrast, at high rainfall (\uffe2\uff89\uffa51500 mm/yr) and positive water balance, the effect of plants on nutrient distributions diminishes with soil age as leaching losses overwhelm the uplift and retention of nutrients by plants after 350 kyr of soil development. The effect of plants on soil nutrient distributions can also be mediated by the movement of iron (Fe), and substantial Fe losses at high rainfall on the older flows are highly correlated with P losses. Thus redox\uffe2\uff80\uff90driven redistribution of Fe may place a further abiotic constraint on nutrient retention by plants. In combination, these data indicate that the effects of soil aging on plant uplift and retention of nutrients differ markedly with precipitation, and we view this as a potentially fruitful area for future research.

We evaluated effects of biochar rate and application method on soil properties, nutrient balance, biomass production, and water quality. Three replications of eight sorghum [ (L.) Moench] treatments were installed in box lysimeters under greenhouse conditions. Treatments comprised increasing rates (0, 1.5, and 3.0 Mg ha) of topdressed or incorporated biochar supplemented with N fertilizer or N, P, and K fertilizer. Simulated rain was applied at 21 and 34 d after planting, and mass runoff loss of N, P, and K was measured. A mass balance of total N, P, and K was performed after 45 d. Returning 3.0 Mg ha of biochar did not affect sorghum biomass, soil total, or Mehlich-3-extractable nutrients compared to control soil. Yet, biochar contributed to increased concentration of dissolved reactive phosphorus (DRP) and mass loss of total phosphorus (TP) in simulated runoff, especially if topdressed. It was estimated that up to 20% of TP in topdressed biochar was lost in surface runoff after two rain events. Poor recovery of nutrients during pyrolysis and excessive runoff loss of nutrients for topdressed biochar, especially K, resulted in negative nutrient balances.

Specifically, designed biostimulation and bioaugmentation strategies were compared with and without adding vermicompost. The polluted soil harboring multiple contaminants, partially attenuated for years, was used. The initial profile showed enrichment in heavy linear alkanes, suggesting a previous moderate weathering. The application of vermicompost increased five and two times the amounts of available phosphorus (P) and exchangeable potassium (K), respectively, as a direct consequence of the organic amendment addition. The microbial activity increased due to soil acidification, which influenced the solubility of P and other micronutrients. It also impacted the predominance and variability of the different microbial groups and the incubation, as reflected by phospholipid fatty acid (PLFA) results. An increase in the alkaline phosphatases and proteases linked to bacterial growth was displayed.

In this study, bioremediation strategies and an organic amendment have been tested to verify the remediation of soil contaminated with different hydrocarbons, mineral oils, and heavy metals. Specifically, designed biostimulation and bioaugmentation strategies were compared with and without adding vermicompost. The polluted soil harboring multiple contaminants, partially attenuated for years, was used. The initial profile showed enrichment in heavy linear alkanes, suggesting a previous moderate weathering. The application of vermicompost increased five and two times the amounts of available phosphorus (P) and exchangeable potassium (K), respectively, as a direct consequence of the organic amendment addition. The microbial activity increased due to soil acidification, which influenced the solubility of P and other micronutrients. It also impacted the predominance and variability of the different microbial groups and the incubation, as reflected by phospholipid fatty acid (PLFA) results. An increase in the alkaline phosphatases and proteases linked to bacterial growth was displayed. This stimulation of microbial metabolism correlated with the degradation rates since TPHs degradation\u2019 efficiency after vermicompost addition reached 32.5% and 34.4% of the initial hydrocarbon levels for biostimulation and bioaugmentation, respectively.

However, the nutrient carry-over to the following crop depends not only on the amount of nutrients accumulated in individual catch crop plant materials but also on the specific degradation properties of their tissues, i.e. the temporal quantitative and qualitative release of scavenged nutrients. In our experiment we investigated the morphological and nutritional response of maize to 6 different pre-grown catch crop variants including pure stands and mixtures. \nAt two field sites in Germany (Asendorf - Lower Saxony and Triesdorf - Bavaria), maize (seeding rate: 9.4 seeds m-2) was established either after pure cultures of mustard, phacelia, bristle oat and Egyptian clover, after a mixture of these 4 species or after a commercial mixture of the DSV with a higher species diversity called TerraLife MaisPro. Their single-species nutrient accumulation was already published in the BonaRes-database under \u201cCatch crop nutrient uptake 1st crop rotation cycle\u201d. Fallow plots were included as control. Maize was fertilized with 160 kg N ha-1 in Asendorf and 190 kg N ha-1 in Triesdorf. Since nutrient release from catch cops might temporarily vary, we studied the morphological and nutritional response of maize at 4 developmental stages ranging from leaf development over shoot elongation and flowering to cob development. As morphological parameters we investigated the number of leaves, tillers and cobs. In order to study the nutritional response we examined the shoot biomass, chlorophyll content or SPAD values and different nutrient concentrations in young and old leaves as well as the nitrate concentration in the press sap obtained from a 1 cm-piece of the stem base as marker for the nitrogen nutritional status. At both locations, the experiment was repeated in two subsequent years (2016 and 2017) and represented each the initial starting point of a wheat-catch crop-maize long-term rotation. Thus, maize response was tested in total in 4 environments. \nIn general we could not observe any significant impact of the pre-grown catch crop variant on morphological or nutritional shoot parameters at any of the investigated developmental stages and in none of the test environments. However, catch crop effects often develop in the long run when included regularly in a crop rotation.", "formats": [{"name": "CSV"}], "keywords": ["Zea mays", "Poaceae", "Shoots", "leaves", "Nitrates", "Nitrogen", "Elements", "Chlorophylls", "nutrient cycling in ecosystems", "Plant morphology", "Catch cropping", "Crop rotation", "Catch crops", "Sinapis alba", "Phacelia tanacetifolia", "Mustard", "Trifolium alexandrinum", "Mustard", "Phacelia", "oats", "maize", "Phosphorus", "Potassium", "Iron", "Carbon", "Magnesium", "Zinc", "Manganese", "Tillering", "biomass", "Landwirtschaftliche Anlagen und Aquakulturanlagen", "Maize", "Nutritional state", "pre-grown catch crops mineral elements", "opendata"], "contacts": [{"name": "Heuermann, Diana", "organization": "Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben", "position": "Staff member (Molecular Plant Nutrition)", "roles": ["author"], "phones": [{"value": "0049 39482 5514"}], "emails": [{"value": "heuermannd@ipk-gatersleben.de"}], "addresses": [{"deliveryPoint": ["Correnstra\u00dfe 3"], "city": "Stadt Seeland", "administrativeArea": "Saxony-Anhalt", "postalCode": "06466", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Wir\u00e9n, Nicolaus von", "organization": "Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben", "position": "Department head", "roles": ["projectLeader"], "phones": [{"value": "0049 39482 5603"}], "emails": [{"value": "vonwiren@ipk-gatersleben.de"}], "addresses": [{"deliveryPoint": ["Correnstra\u00dfe 3"], "city": "Stadt Seeland", "administrativeArea": "Saxony-Anhalt", "postalCode": "06466", "country": "Germany"}], "links": [{"href": null}]}, {"name": "BonaRes Data Centre", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data' - WG Geodata", "roles": ["publisher"], "phones": [{"value": "+49 33432 82 171"}], "emails": [{"value": "bonares-datenzentrum@zalf.de"}], "addresses": [{"deliveryPoint": ["Eberswalder Strasse 84"], "city": "M\u00fcncheberg", "administrativeArea": "Brandenburg", "postalCode": "15374", "country": "Germany"}], "links": [{"href": null}]}, {"organization": "Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben", "roles": ["contributor"]}], "title_alternate": "Biomass, development and nutrient accumulation in the above-ground biomass of maize after different catch crop variants in the first cycle of a wheat-catch crop-maize long-term rotation"}, "links": [{"href": "https://maps.bonares.de/mapapps/resources/apps/bonares/index.html?lang=en&doi=2dcc638c-6eca-4f91-a860-8ccd5cf3a2ef", "rel": "download"}, {"rel": "self", "type": "application/geo+json", "title": "2dcc638c-6eca-4f91-a860-8ccd5cf3a2ef", "name": "item", "description": "2dcc638c-6eca-4f91-a860-8ccd5cf3a2ef", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/2dcc638c-6eca-4f91-a860-8ccd5cf3a2ef"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2019-06-17T00:00:00Z"}}, {"id": "3132814296", "type": "Feature", "geometry": null, "properties": {"updated": "2026-05-30T16:27:29Z", "type": "Dataset", "title": "Silicon isotopes in Arctic and sub-Arctic glacial meltwaters", "description": "Open AccessSupplement to: Hatton, Jade Elizabeth; Hendry, Katharine R; Hawkings, Jonathan; Wadham, Jemma; Opfergelt, Sophie; Kohler, Tyler; Yde, Jacob; Stibal, Marek; \u017d\u00e1rsk\u00fd, Jakub (2019): Silicon isotopes in Arctic and sub-Arctic glacial meltwaters: the role of the subglacial weathering in the silicon cycle.

With thawing permafrost, especially in ice-rich regions such as the Yedoma domain, vast amounts of organic carbon previously stored in deep frozen deposits are unlocked and therefore available to undergo microbial mineralization leading to potential carbon dioxide and methane emissions. Mineral elements interfere with organic carbon degradation through various processes: i) mineral protection (aggregation, adsorption, and complexation) stabilizes organic carbon and mitigates its mineralization, and ii) change in mineral nutrients availability affects microorganisms growth and metabolic activity. Despite huge efforts to assess organic carbon stocks and lability in permafrost regions, there is a lack of studies on the mineral component assessment, which we aim to close with this dataset. Here, we provide a large-scale Yedoma domain Mineral Concentrations Assessment (YMCA) dataset of never thawed (since deposition) ice-rich Yedoma permafrost and previously thawed and partly refrozen Alas deposits. We used a portable X-ray fluorescence device (pXRF) for Si, Al, Fe, Ca, K, Ti, Mn, Zn, Sr and Zr concentration measurements on 1,292 sediment samples. Portable XRF measured concentrations trueness was calibrated using standard alkaline fusion and ICP-OES measurement from a subset of 144 samples (R\u00b2 from 0.725 to 0.996). This methodology lead to the creation of the Yedoma domain Mineral Concentration Assessment (YMCA) dataset, a necessary step to estimate mineral element stocks in never thawed Yedoma and previously thawed Alas deposits. Practically, the YMCA dataset is organized as follow: (i) all site and sample properties: sample ID, type of deposit, site location, profile ID, GPS coordinates, country, lithology, unconsolidated sediment type, geological epoch, samples depth below surface level (b.s.l) or height above sea/river level (a.s.l), sediment characteristics, bulk density, gravimetric and absolute ice content, total organic carbon content; (ii) the Si, Al, Fe, Ca, K, Ti, Mn, Zn, Sr and Zr concentrations (corrected based on linear regressions) in Yedoma and Alas deposits (n=1292).", "keywords": ["Density", "Permafrost", "Profile ID", "gravimetric", "Density", " bulk", " permafrost", "Aluminium", "total", "Sample code/label", "Portable X ray fluorescence device", "Titanium", "Mineral element", "Yedoma", "Portable X-ray fluorescence device", "Description", "Number", "Lithology/composition/facies", "Sample code label", "6.

The redox potential (Eh) was measured in situ and pore water was sampled weekly from three different depths of the lysimeters to determine pH and the element concentrations total C, P, Al, Fe, Mn, Zn, Ca, Mg, and K, as well as inorganic and organic C (DIC, DOC), PO43--P, SO42--S, NO2-- and NO3- -N, Cl- and Br- in solutions (0.45 \u00b5m and 1 \u00b5m). Thus, information about different element concentrations at different redox potentials and pH was gained over a period of about 5 months in 2019.", "formats": [{"name": "CSV"}], "keywords": ["Soil", "soil water", "elements", "redox potential", "dissolved organic phosphorus", "plant available phosphorus", "total phosphorus", "carbon", "dissolved inorganic carbon", "dissolved organic carbon", "nitrates", "nitrites", "sulphates", "calcium", "potassium", "pH", "opendata", "Boden", "Bodenwasser", "Redoxreaktion", "Phosphor"], "contacts": [{"name": "Baumann, Karen", "organization": "University of Rostock", "position": "post-doc", "roles": ["author"], "phones": [{"value": "493 814 983 184"}], "emails": [{"value": "karen.baumann@uni-rostock.de"}], "addresses": [{"deliveryPoint": ["Justus-von-Liebig-Weg 6"], "city": "Rostock", "administrativeArea": "Mecklenburg-Vorpommern", "postalCode": "18051", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Leinweber, Peter", "organization": "University of Rostock", "position": "Professor", "roles": ["projectLeader"], "phones": [{"value": "493 814 983 120"}], "emails": [{"value": "peter.leinweber@uni-rostock.de"}], "addresses": [{"deliveryPoint": ["Justus-von-Liebig-Weg 6"], "city": "Rostock", "administrativeArea": "Mecklenburg-Vorpommern", "postalCode": "18051", "country": "Germany"}], "links": [{"href": null}]}, {"name": "BonaRes Data Centre", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data Analysis & Simulation' - WG Geodata", "roles": ["publisher"], "phones": [{"value": "+49 33432 82 171"}], "emails": [{"value": "bonares-datenzentrum@zalf.de"}], "addresses": [{"deliveryPoint": ["Eberswalder Strasse 84"], "city": "M\u00fcncheberg", "administrativeArea": "Brandenburg", "postalCode": "15374", "country": "Germany"}], "links": [{"href": null}]}, {"organization": "University of Rostock", "roles": ["contributor"]}]}, "links": [{"href": "https://maps.bonares.de/mapapps/resources/apps/bonares/index.html?lang=en&mid=4d171e57-0006-48f8-9dfd-367d724ecc9f", "rel": "information"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/906cdf90-8ee0-4e9f-b13a-68e2175810ef", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "4d171e57-0006-48f8-9dfd-367d724ecc9f", "name": "item", "description": "4d171e57-0006-48f8-9dfd-367d724ecc9f", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/4d171e57-0006-48f8-9dfd-367d724ecc9f"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2022-04-08T00:00:00Z"}}, {"id": "PMC6090968", "type": "Feature", "geometry": null, "properties": {"updated": "2026-05-30T16:29:50Z", "type": "Journal Article", "created": "2018-08-02", "title": "Amoxicillin/clavulanic acid-induced pancreatitis: case report", "description": "Acute pancreatitis is an acute inflammation of the pancreas that varies in severity from mild to life threatening usually requiring hospitalization. The true incidence of drug-induced pancreatitis (DIP) is indeterminate due to the inadequate documentation of case reports of DIP. Here we present the case of amoxicillin/clavulanic acid-induced pancreatitis in a previously healthy male after excluding all other causes of pancreatitis.A 58-year-old Caucasian man presenting for acute sharp abdominal pain with associated nausea and heaves. Pain was non-radiating and worsening with movement. Patient had no constitutional symptoms. The only medication he received prior to presentation was amoxicillin/clavulanic acid as prophylaxis for a dental procedure with his symptoms starting on day 9th of therapy. Laboratory studies revealed mild leukocytosis, increased levels of serum lipase, amylase, and C-reactive protein (CRP). Abdominal computed tomography (CT) was notable for acute pancreatitis with no pseudocyst formation. Hence, patient was diagnosed with mild acute pancreatitis that was treated with aggressive intravenous (IV) hydration and pain management with bowel rest of 2\u00a0days duration and significant improvement being noticed within 72\u00a0h. On further questioning, patient recalled that several years ago he had similar abdominal pain that developed after taking amoxicillin/clavulanic acid but did not seek medical attention at that time and the pain resolved within few days while abstaining from food intake. All other causes of pancreatitis were ruled out in this patient who is non-alcoholic, non-smoker, and never had gallstones. Abdominal ultrasound and magnetic resonance cholangiopancreatography (MRCP) eliminated out the possibility of gallstones, biliary ductal dilatation, or choledocholithiasis. Patient had no hypertriglyceridemia nor hypercalcemia, never had endoscopic retrograde cholangiopancreatography (ERCP), never took steroids, has no known malignancy, infection, trauma, or exposure to scorpions.This case describes a patient with DIP after the intake of amoxicillin/clavulanic acid and when all other common causes of acute pancreatitis were excluded. Only two other case reports were available through literature review regarding amoxicillin/clavulanic acid- induced pancreatitis. We again stress on the importance of identifying and reporting cases of DIP to raise awareness among physicians and clinicians.", "keywords": ["Male", "Amoxicillin/clavulanic acid", "Cholangiopancreatography", " Magnetic Resonance", "Vomiting", "Amoxicillin", "Case Report", "Nausea", "RC799-869", "Drug-induced pancreatitis", "Diseases of the digestive system.
