The amount of amino sugars and their ratios can serve as reliable indicators for bacterial and fungal contribution. We compare forest fl oor microbial residues (amino sugars) beneath three canopy-tree species (Sugar Maple (SM), Acer saccharum Marsh; Basswood (BA), Tilia americana L.; Eastern Hemlock, Tsuga canadensis L.) replicated in fi ve plots in an upper Michigan old-growth forest. We hypothesized that because individual tree species develop a unique microbial community over time, they will accumulate microbial residues to different degrees. In this study at three tree species sites, the absolute amount of fungal residue (glucosamine (GluN)) was relatively constant, while absolute quantities of bacterial residues (galactosamine (GalN) and muramic acid (MurA)) were least in the Hemlock site. Amino sugar ratios revealed that microbial residues were compositionally distinct in the three sites. The lower ratios of GluN to GalN and GluN to MurA in BA and SM sites relative to Hemlock site indicate the lower net accumulations of GalN and MurA in Hemlock site. In terms of microbial contribution to carbon and nitrogen cycle in forest soils, we suggest that caution may be needed when using amino sugars as a tool, especially for nitrogen pool assessment, as the amino sugars are diluted by plant-derived litter.

Phosphorus (P) is an essential macro\uffe2\uff80\uff90nutrient required for plant metabolism and growth. Low P availability could potentially limit plant responses to elevated carbon dioxide (eCO2), but consensus has yet to be reached on the extent of this limitation. Here, based on data from experiments that manipulated both CO2 and P for young individuals of woody and non\uffe2\uff80\uff90woody species, we present a meta\uffe2\uff80\uff90analysis of P limitation impacts on plant growth, physiological, and morphological response to eCO2. We show that low P availability attenuated plant photosynthetic response to eCO2 by approximately one\uffe2\uff80\uff90quarter, leading to a reduced, but still positive photosynthetic response to eCO2 compared to those under high P availability. Furthermore, low P limited plant aboveground, belowground, and total biomass responses to eCO2, by 14.7%, 14.3%, and 12.4%, respectively, equivalent to an approximate halving of the eCO2 responses observed under high P availability. In comparison, low P availability did not significantly alter the eCO2\uffe2\uff80\uff90induced changes in plant tissue nutrient concentration, suggesting tissue nutrient flexibility is an important mechanism allowing biomass response to eCO2 under low P availability. Low P significantly reduced the eCO2\uffe2\uff80\uff90induced increase in leaf area by 14.3%, mirroring the aboveground biomass response, but low P did not affect the eCO2\uffe2\uff80\uff90induced increase in root length. Woody plants exhibited stronger attenuation effect of low P on aboveground biomass response to eCO2 than non\uffe2\uff80\uff90woody plants, while plants with different mycorrhizal associations showed similar responses to low P and eCO2 interaction. This meta\uffe2\uff80\uff90analysis highlights crucial data gaps in capturing plant responses to eCO2 and low P availability. Field\uffe2\uff80\uff90based experiments with longer\uffe2\uff80\uff90term exposure of both CO2 and P manipulations are critically needed to provide ecosystem\uffe2\uff80\uff90scale understanding. Taken together, our results provide a quantitative baseline to constrain model\uffe2\uff80\uff90based hypotheses of plant responses to eCO2 under P limitation, thereby improving projections of future global change impacts.

The aim of this study was to examine how intensified silviculture affects timber production (sawlogs and pulpwood) and its economic profitability (net present value [NPV], with 2 per cent interest rate) based on forest ecosystem model simulations. The study was conducted on Norway spruce and Scots pine stands located on medium-fertile upland forest sites under middle boreal conditions in Finland, under current climate and minor climate change (the RCP2.6 forcing scenario). In intensified silviculture, improved regeneration materials were used, with 10\uffe2\uff80\uff9320 per cent higher growth than the unimproved materials, and/or nitrogen (N) fertilization of 150 kg ha\uffe2\uff88\uff921, once or twice during a rotation of 50\uffe2\uff80\uff9370 years. Compared to the baseline management regime, the use of improved seedlings, alone or together with N fertilization, increased timber production by up to 26\uffe2\uff80\uff9328 per cent and the NPV by up to 32\uffe2\uff80\uff9360 per cent over rotation lengths of 60\uffe2\uff80\uff9370 years, regardless of tree species (although more in spruce) or climate applied. The use of improved seedlings affected timber yield and NPV more than N fertilization. Minor climate change also increased these outcomes in Scots pine, but not in Norway spruce.

This study was conducted to examine the effects of mowing and nitrogen (N) addition on soil respiration and their dependences upon vegetation types in an oldfield grassland of northern China. Methods Soil respiration, temperature, moisture and aboveground net primary productivity (ANPP) and belowground net primary productivity (BNPP) were examined in response to mowing and N addition among the three patches dominated by different species (named as grass, forb and mixed patches, respectively) in the growing seasons (May\u2013October) from 2006 to 2008. Important Findings Across the 3 years, soil respiration in the grass patch was greater than those in the forb and mixed patches, which could have been ascribed to the higher soil moisture (SM) in the grass patch. Mowing had no impact on soil respiration due to unaltered SM and plant growth. Soil respiration was stimulated by 6.53% under N addition, and the enhancement was statistically significant in 2006 but not in 2007 or 2008 because of the limited water availability in the later 2 years. There were no interactive effects between mowing and N addition on soil respiration. Soil respiration showed positive dependence upon SM, ANPP and BNPP across plots. The results suggest that soil water availability and plant growth could be the primary factors in controlling the temporal and spatial variations in soil respiration and its response to different treatments.

The impact of N addition on EEA may differ across different age stands with different organic matter quality.

Methods We added three levels of N (0, 20 and 50 kg N ha \u22121 year \u22121 ) in three age stands (11, 20 and 45 years old) of Larix principis-rupprech- tii plantation in North China. We measured potential activities of \u03b2-1,4-glucosidase (BG), cellobiohydrolase (CB), \u03b2-1,4-N-acetyl- glucosaminidase (NAG) and phenol oxidase (PO) in litter (organic horizon) and mineral soil (0-10 cm) during the second growing sea- son after N amendment. We also measured C and N concentrations, microbial biomass C and N, and KCl-extractable ammonium and nitrate in both litter and mineral soil. temperature. Stand age had a strong effect on EEA in both litter and mineral soil, and this effect differed between litter and mineral soil as well as between different enzymes. N addition did not signifi- cantly affect the activities of BG or CB but significantly suppressed the activity of NAG in litter. We also found stand age-specific responses of PO activity to N addition in both litter and mineral soil. N addition suppressed PO activity of the high C:N ratio litters in 20- and 45-year-old stands but had no significant effect on PO activity of the low C:N ratio litter in 11-year-old stand. Moreover, N addition inhibited PO activity of the high C:N ratio soil in 20-year- old stand but had no significant impact on PO activity of the low C:N ratio soils in 11- and 45-year-old stands. Overall, stand age had a greater effect on EEA in litter and mineral soil compared to 2 years of N addition. Moreover, the effect of N addition on PO activity is stand age dependent, which may affect the long-term soil carbon storage in this forest.", "keywords": ["0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "14.

Methods We conducted field manipulations of precipitation, including ambient precipitation as a control (CK), double precipitation (DP) and no precip- itation (NP), for 3 years in three forests with different stand ages (broad- leaf forest (BF), mixed forest (MF) and pine forest (PF)) in subtropical China. At the end of the experiment, soil samples were collected to assay SOC content, readily oxidizable organic carbon (ROC) and non-readily oxidizable organic carbon (NROC), as well as soil microbial biomass carbon (MBC), pH and total nitrogen content. Samples from the forest floors were also collected to analyze carbon (C) functional groups (i.e. alkyl C, aromatic C, O-alkyl C and carbonyl C). Furthermore, fine root biomass was measured periodically throughout the experiment. Important Findings Among the forests, ROC content did not exhibit any notable differ- ences, while NROC content increased significantly with the stand age. This finding implied that the SOC accumulation observed in these forests resulted from the accumulation of NROC in the soil, a mechanism for SOC accumulation in the mature forests of south- ern China. Moreover, NP treatment led to significant reductions in both ROC and NROC content and therefore reduced the total SOC content in all of the studied forests. Such decreases may be due to the lower plant-derived C inputs (C quantity) and to the changes in SOC components (C quality) indicated by C functional groups analyses under NP treatment. DP treatment in all the forests also tended to decrease the SOC content, although the decreases were not statistically significant with the exception of SOC and ROC con- tent in PF. This finding indicated that soils in MF and in BF may be more resistant to precipitation increases, possibly due to less water limitations under natural conditions in the two forests. Our results therefore highlight the different responses of SOC and its fractions to precipitation changes among the forests and suggest that further studies are needed to improve our understanding of SOC dynamics in such an important C sink region.", "keywords": ["13.

To test this hypothesis, the effects of elevated [CO(2)] on yield components, biomass, N uptake, and leaf photosynthesis of cultivars with different maturity groups were examined for 2 years using a free-air CO(2) enrichment (FACE).

This work extends our previous work to larger domains and hence is valid for longer times. Unlike the model used previously, which considered only a small region of soil about the root, we considered an effectively infinite volume of bulk soil about the rhizosphere. We asked the question: At what distance away from root surfaces do the specific structural features of root-hair and soil aggregate morphology not matter because average properties start dominating the nutrient transport? The resulting model was used to capture bulk and rhizosphere soil properties by considering representative volumes of soil far from the root and adjacent to the root, respectively. By increasing the size of the volumes that we considered, the diffusive impedance of the bulk soil and root uptake were seen to converge. We did this for two different values of water content. We found that the size of region for which the nutrient uptake properties converged to a fixed value was dependent on the water saturation. In the fully saturated case, the region of soil we needed to consider was only of radius 1.1mm for poorly soil-mobile species such as phosphate. However, in the case of a partially saturated medium (relative saturation 0.3), we found that a radius of 1.4mm was necessary. This suggests that, in addition to the geometrical properties of the rhizosphere, there is an additional effect of soil moisture properties, which extends further from the root and may relate to other chemical changes in the rhizosphere. The latter were not explicitly included in our model.", "keywords": ["0301 basic medicine", "550", "Oryza", "04 agricultural and veterinary sciences", "15.

Humus samples were collected 12 growing seasons after the start of a simulated acid rain experiment situated in the subarctic environment. The acid rain was simulated with H 2 SO 4 , a combination of H 2 SO 4 and HNO 3 , and HNO 3 at two levels of moderate acidic loads close to the natural anthropogenic pollution levels of southern Scandinavia. The higher levels of acid applications resulted in acidification, as defined by humus chemistry. The concentrations of base cations decreased, while the concentrations of exchangeable H + , Al, and Fe increased. Humus pH decreased from 3.83 to 3.65. Basal respiration decreased with decreasing humus pH, and total microbial biomass, measured by substrate-induced respiration and total amount of phospholipid fatty acids (PLFA), decreased slightly. An altered PLFA pattern indicated a change in the microbial community structure at the higher levels of acid applications. In general, branched fatty acids, typical of gram-positive bacteria, increased in the acid plots. PLFA analysis performed on the bacterial community growing on agar plates also showed that the relative amount of PLFA specific for gram-positive bacteria increased due to the acidification. The changed bacterial community was adapted to the more acidic environment in the acid-treated plots, even though bacterial growth rates, estimated by thymidine and leucine incorporation, decreased with pH. Fungal activity (measured as acetate incorporation into ergosterol) was not affected. This result indicates that bacteria were more affected than fungi by the acidification. The capacity of the bacterial community to utilize 95 different carbon sources was variable and only showed weak correlations to pH. Differences in the toxicities of H 2 SO 4 and HNO 3 for the microbial community were not found.

White pine (Pinus strobus L.) is planted extensively following reclamation of surface-mined land in the eastern coalfields. Little information exists on the productive potential of forests growing on reclaimed mined land and the response of these forests to intermediate stand treatments such as thinning. A thinning study was established in a 17-year-old white pine stand growing on a reclaimed surface mine in Wise County in southwest Virginia. A random complete block design was used to evaluate the growth response 9 growing seasons after thinning, when the stand was 26 years old. Stand parameters were projected to age 30 using a stand table projection. Site index of the stand was found to be 105 ft at a base age of 50 years. Thinning increased the diameter growth of the residual trees to 0.3 in. year\uffe2\uff88\uff921 compared with 0.2 in. year\uffe2\uff88\uff921 for the unthinned treatment; however, at age 26, there was no difference in volume or value per acre. When projected to age 30, the unthinned treatment had a volume of 6,530 ft3 ac\uffe2\uff88\uff921 but was only worth $3,564 ac\uffe2\uff88\uff921, whereas the thinned treatment was projected to have 6,654 ft3 ac\uffe2\uff88\uff921, which was worth $4,559 ac\uffe2\uff88\uff921 due to a larger percentage of the volume in sawtimber size classes. These results indicate that commercial forestry is a viable alternative for reclamation of surface-mined lands and that stands growing on reclaimed mined land can respond well to intermediate stand treatments.

Widespread soil acidification due to atmospheric acid deposition and agricultural fertilization may greatly accelerate soil carbonate dissolution and CO2 release. However, to date, few studies have addressed these processes. Here, we use meta-analysis and nationwide-survey datasets to investigate changes in soil inorganic carbon (SIC) stocks in China. We observe an overall decrease in SIC stocks in topsoil (0\uffe2\uff80\uff9330\uffc2\uffa0cm) (11.33\uffc2\uffa0g C m\uffe2\uff80\uff932 yr\uffe2\uff80\uff931) from the 1980s to the 2010s. Total SIC stocks have decreased by \uffe2\uff88\uffbc8.99\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.24% (1.37\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.37\uffc2\uffa0Pg C). The average SIC losses across China (0.046 Pg C yr\uffe2\uff80\uff931) and in cropland (0.016 Pg C yr\uffe2\uff80\uff931) account for \uffe2\uff88\uffbc17.6%\uffe2\uff80\uff9324.0% of the terrestrial C sink and 57.1% of the soil organic carbon sink in cropland, respectively. Nitrogen deposition and climate change have profound influences on SIC cycling. We estimate that \uffe2\uff88\uffbc19.12%\uffe2\uff80\uff9319.47% of SIC stocks will be further lost by 2100. The consumption of SIC may offset a large portion of global efforts aimed at ecosystem carbon sequestration, which emphasizes the importance of achieving a better understanding of the indirect coupling mechanisms of nitrogen and carbon cycling and of effective countermeasures to minimize SIC loss.Prescribed burning of young unthinned plantations of loblolly pine (Pinus taeda L.) in the South Carolina Piedmont significantly reduced the quantity of individual nutrients in the L layer, but not the F + H layers of the forest floor. Burning reduced the weight of the L layer by 60 percent but the weight of the combined F + H layers was unaffected by the relatively fast-moving strip-head fires. Nutrient losses by ash convection from the L layer during the prescribed fire ranged from 3.6 lbs/ac for P to 23.1 lbs/ac for N. Some impaction of nutrients released in burning on pine canopies was detected by analysis of throughfall and stemflow. However, quantities of nutrients intercepted and released by the canopy are small when compared to nutrient transfer by leaf fall and precipitation. The canopy and stems markedly altered the nutrient concentrations of intercepted precipitation.

In the short-term studies, elevated CO(2) caused significant decreases in tissue N concentration and the extent of the decrease varied with species.

Cultivation of forest lands leads to substantial losses in both biomass and soil carbon, whereas forest regrowth is considered to be a significant carbon sink. We examined below- and aboveground carbon stocks along a chronosequence of Norway spruce (Picea abies (L.) Karst.) stands (0-62 years old) regenerating on abandoned meadows in the Southern Alps. A 130-year-old mixed coniferous Norway spruce-white fir (Abies alba Mill.) forest, managed by selection cutting, was used as an undisturbed control. Deforestation about 260 years ago led to carbon losses of 53 Mg C ha(-1) from the organic layer and 12 Mg C ha(-1) from the upper mineral horizons (Ah, E). During the next 200 years of grassland use, the new Ah horizon sequestered 29 Mg C ha(-1). After the abandonment of these meadows, carbon stocks in tree stems increased exponentially during natural forest succession, levelling off at about 190 Mg C ha(-1) in the 62-year-old Norway spruce and the 130-year-old Norway spruce-white fir stands. In contrast, carbon stocks in the organic soil layer increased linearly with stand age. During the first 62 years, carbon accumulated at a rate of 0.36 Mg C ha(-1) year(-1) in the organic soil layer. No clear trend with stand age was observed for the carbon stocks in the Ah horizon. Soil respiration rates were similar for all forest stands independently of organic layer thickness or carbon stocks, but the highest rates were observed in the cultivated meadow. Thus, increasing litter inputs by forest vegetation compared with the meadow, and constantly low decomposition rates of coniferous litter were probably responsible for continuous soil carbon sequestration during forest succession. Carbon accumulation in woody biomass seemed to slow down after 60 to 80 years, but continued in the organic soil layer. We conclude that, under present climatic conditions, forest soils act as more persistent carbon sinks than vegetation that will be harvested, releasing the carbon sequestered during tree growth.", "keywords": ["Ecology", "Water", "04 agricultural and veterinary sciences", "Carbon Dioxide", "15.

In both species, mycorrhizal inoculation significantly increased uptake capacity for NO3-, but not for NH4+. In sweetgum, the mycorrhizal effect on NO3- and NH4+ uptake capacity depended on growth [C02].

The -N and +N pretreated trees were then placed in growth chambers and grown in 350 (ambient) or 700 ppm (elevated) of a 13CO2 atmosphere for 24 weeks. In all treatments, trees were supplied with 4 mM 15N during the experiment. Irrespective of tree N reserves, elevated [CO2] increased cumulative carbon (C) uptake by about 30% at Week 24 compared with that for trees in the ambient treatment. Elevated [CO2] also caused a shift in C allocation to belowground compartments, which was more pronounced in -N trees than in +N trees. In +N trees, belowground allocation of new C at Week 24 was 67% in ambient [CO2] compared with 70% in elevated [CO2]. The corresponding values for -N trees were 70 and 79%. The increase in C allocation in response to elevated [CO2] was most evident as an increase in belowground respiration; however, specific root respiration was unaffected by the CO2 or N treatments. Although elevated [CO2] increased root growth and belowground respiration, it had no effect on N uptake at Week 24. As a result of increased C uptake, N concentrations were decreased in trees in the elevated [CO2] treatment compared with trees in the ambient treatment in both N treatments. Partitioning of new N uptake was unaffected by elevated [CO2] in +N trees. In -N trees, however, N allocation to the stem decreased in response to elevated [CO2] and N allocation to fine roots increased, suggesting a reduction in the formation of N reserves in response to elevated [CO2].

While many genes up-regulated by auxin have been characterized, less is known about the genes that are down-regulated by auxin. We isolated and characterized an auxin-repressed gene (RpARP) from the tree legume, Robinia pseudoacacia L. A sequence similarity search in public databases showed that the RpARP gene has homologs in various higher plants including monocots and dicots. The deduced amino acid sequences are highly conserved among these homologs (up to 85% identity). Northern blot analysis showed that auxin repressed RpARP gene expression and that repression was dependent on the presence of metabolizable sugar and on protein synthesis. In addition, cold treatment abolished the auxin-mediated repression of RpARP gene expression. Results from transgenic plant analyses suggest that RpARP gene expression is posttranscriptionally regulated by auxin and by the untranslated regions. Sequence analysis of the promoter region (-70 and -500 bp upstream of the putative transcription initiation site) of the RpARP gene identified four sucrose-repressible response elements (TATCCAT-motifs; Huang et al. 1990), suggesting that the cis-elements responsible for regulation by sucrose are located in the promoter region.

We conducted a multivariate analysis with two independent variables of soil temperature and water and a categorical variable representing the thinning event to simulate soil respiration and assess the effect of thinning. Thinning did not change the sensitivity of soil respiration to temperature or to water, but decreased total soil respiration by 13% at a given temperature and water content.

We explored the timing of spring xylogenesis and its potential drivers in homogeneous mature forest stands in a temperate European region. Three species with contrasting leaf development dynamics and wood anatomy were studied: European beech, silver birch and pedunculate oak. Detailed phenological observations of xylogenesis and leaf phenology were performed from summer 2017 until spring 2018. Cambium reactivation (CR) occurred before the buds of oak and birch were swollen, whereas these two phenological phases were concurrent for beech. On the other hand, initial earlywood vessels were fully differentiated (FDIEV) after leaf unfolding for all three species. Timing of CR was correlated to average ring-width of the last 10\uffc2\uffa0years (2008\uffe2\uff80\uff9317), tree diameter and, partially, with tree age. In addition, the timing of FDIEV was correlated to tree age and previous year\uffe2\uff80\uff99s autumn phenology, i.e., timing of wood growth cessation and onset of leaf senescence. Multivariate models could explain up to 68% of the variability of CR and 55% of the variability of FDIEV. In addition to the \uffe2\uff80\uff98species\uffe2\uff80\uff99 factor, the variability could be explained by ca 30% by tree characteristics and previous year\uffe2\uff80\uff99s autumn phenology for both CR and FDIEV. These findings are important to better identify which factors (other than environment) can be driving the onset of the growing season, and highlight the influence of tree growth characteristics and previous year\uffe2\uff80\uff99s phenology on spring wood phenology, wood formation and, potentially, forest production.

The increase in N concentration in the live fine roots could be attributed to the increase in soil N availability due to soil warming. Net N mineralization was negatively correlated with both live and dead fine roots in the mineral soil that is home to the majority of roots, suggesting that soil warming increases N mineralization, decreases fine root biomass and thus decreases C allocation belowground.", "keywords": ["2.

When multiple stressors co-occur, their combined impact on plant growth is often greater than expected based on single-factor studies (i.e., synergistic), potentially causing catastrophic dysfunction of physiological processes from an otherwise recoverable situation. Drought and herbivory are two stressors that commonly co-occur in forested ecosystems, and have the potential to 'overlap' in their impacts on various plant traits and processes. However, the combined impacts from these two stressors may not be predictable based on additive models from single-stressor studies. Moreover, the impacts and subsequent recovery may be strongly influenced by the relative intensities of each stressor. Here, we applied drought stress and simulated bark-feeding herbivory at three levels of intensity (control, moderate and severe) in a full factorial design on young Pinus sylvestris L. seedlings. We assessed if the combined effects from two stressors were additive (responses were equal to the sum of the single-factor effects), synergistic (greater than expected) or antagonistic (less than expected) on a suite of morphological and physiological traits at the leaf-, tissue- and whole-plant level. We additionally investigated whether recovery from herbivory was dependent on relief from drought. The two stressors had synergistic impacts on specific leaf area and water-use efficiency, additive effects on height and root-to-shoot ratios, but antagonistic effects on photosynthesis, conductance and, most notably, on root, shoot and whole-plant biomass. Nevertheless, the magnitude and direction of the combined impacts were often dependent on the relative intensities of each stressor, leading to many additive or synergistic responses from specific stressor combinations. Also, seedling recovery was far more dependent on the previous year's drought compared with the previous year's herbivory, demonstrating the influence of one stressor over another during recovery. Our study reveals for the first time, the importance of not only the presence or absence of drought and herbivory stressors, but also shows that their relative intensities are critical in determining the direction and magnitude of their impacts on establishing seedlings.", "keywords": ["0106 biological sciences", "Water", "Pinus sylvestris", "Plant Transpiration", "15.

Pyrolyzed biomass waste, commonly called biochar, has attracted interest as a soil amendment. A commercial prototype biochar produced by fast pyrolysis of hardwood dust was examined in soils to determine if it could reduce the damaging effect of allelopathy on arbuscular mycorrhizal (AM) root colonization and on Fusarium crown and root rot of asparagus. In greenhouse studies, biochar added at 1.5 and 3.0% (wt/wt) to asparagus field soil caused proportional increases in root weights and linear reductions in the percentage of root lesions caused by Fusarium oxysporum f. sp. asparagi and F. proliferatum compared with a control. Concomitant with these effects was a 100% increase in root colonization by AM fungi at the 3.0% rate. Addition of aromatic acids (cinnamic, coumaric, and ferulic) that are known allelopathic agents affecting asparagus reduced AM colonization but the deleterious effects were not observed following the application of biochar at the higher rate. When dried, ground, asparagus root and crown tissues infested with Fusarium spp. were added to soilless potting mix at 0, 1, or 5 g/liter of potting mix and then planted with asparagus, there was a decrease in asparagus root weight and increase in disease at 1 g/liter of potting mix but results were inconsistent at the higher residue rate. However, when biochar was added at 35 g/liter of potting mix (roughly 10%, vol/vol), these adverse effects on root weight and disease were equal to the nontreated controls. A small demonstration was conducted in field microplots. Those plots amended with biochar (3.5% [wt/wt] soil) produced asparagus plants with more AM colonization in the first year of growth but, in the subsequent year, biochar-treated plants were reduced in size, possibly due to greater than average precipitation and the ability of biochar to retain moisture that, in turn, may have created conditions conducive to root rot. These studies provide evidence that biochar may be useful in overcoming the deleterious effects of allelopathic residues in replant soils on asparagus.

For this reasons we prolonged the investigations into the following years to evaluate if and how time could overcome the modifications induced by the shocking passage of the fire in the physicochemical parameters previously investigated. Our attention was focused on the organic matter content, aggregate stability, hydrophobic and cementing substances, and or-ganometallic cements. Three years after the passage of the fire, the surficial layers had restored the original conditions regarding organic matter content, aggregate stability, ad the slight water repellence. The subsurficial layers, in which the fire had accumulated trans-located hydrophobic matter, kept these hydrophobic substances quantitatively unaltered, but they appeared more strongly cemented, because the translocated organic matter, far from remaining inactive, could react, complexing polyvalent metals and expanding the organometallic cements.", "keywords": ["13.

Predicting N dynamics of different soil management in short-term studies is difficult because soil properties change slowly. A long-term experiment under a winter wheat-fallow system in the semi-arid region of eastern Oregon provided an opportunity to study the cumulative effects of residue management on the mineralization and plant availability of N. The treatments, established in 1931, included wheat straw burning, incorporation of straw, manure, legume plant residue, or inorganic N. To evaluate N availability to plants, a greenhouse pot study was conducted on the treated soils collected from the 0 to 20-cm depth. Ryegrass (Lolium perenne L.) was grown as an indicator plant for 120 days in 1-kg soil samples treated with different rates of inorganic N and harvested and analyzed for total N at 30-day intervals. At the control rate, ryegrass dry matter yield (DMY) and N uptake from the manuretreated soil were more than 50% higher than from other residue treatments. When adequate nutrients were applied, soil treated long-term with manure had no DMY advantage over long-term inorganic N treatments.

In weathered tropical soils, rates of C loss caused by cultivation are many times faster than those for temperate soils, with a substantial deterioration in soil quality often in less than 10 years. Here we examine the role of minerals and microaggregation in organic matter stability in the search for a stable organic C pool in a semiarid tropical soil (Oxisol) from the Chapada de Araripe in Pernambuco, NE Brazil. In this soil, 14% of the C and N was lost in 6 years of manual shifting cultivation, after which it was abandoned. Carbon in the sand fraction accounted for 22% of total soil C and declined by 40% upon cultivation. Although silt and silt-sized microaggregates accounted for only 10% of total soil mass, they contained nearly half the soil C, which declined by 13% during cultivation. Clay-associated C (27% of soil C) showed no decline because of a mass transfer from sand and silt-sized microaggregates to clay, probably as a result of their destabilization under cultivation. Chemical oxidation with 0.03 M KMnO4 was able to predict the proportion of labile C and indicated a decreased organic matter stability after cultivation. Density and magnetic fractionation indicated that organo-mineral complexes were broken down during cultivation, with a subsequent mineralization of C and redistribution to finer, lighter fractions. The most stable fraction appeared to be in silt-sized microaggregates and in clays of intermediate magnetic susceptibility, indicating its association with Fe of low crystallinity. Even this most resistant fraction showed a 14C age of only about 100 years, approximately double that of the whole soil but only one-tenth of values typical of resistant fractions in temperate soils. This result indicates that organic matter of weathered tropical soils may be less stable than assumed, that rapid degradation of soil quality is possible, and that organic matter management should be a priority for sustainable agriculture.", "keywords": ["2.
