This study shows how precise knowledge of the internal micrometer-scale pore size distribution of biochar can deepen the understanding of the biochar-water interactions in soils. The micrometer-scale porosity of willow biochar was quantitatively and qualitatively characterized using X-ray tomography, 3D image analysis and Helium ion microscopy. The effect of biochar application on clay soil water retention was studied by conventional water retention curve approach. The results indicate that the internal pores of biochar, with sizes of at 50 and 10\u202f\u03bcm (equivalent pore diameter), increased soil porosity and the amount of readily plant available water. After biochar addition, changes in soil porosity were detected at pore size regimes 5\u201310 and 25\u202f\u03bcm, i.e. biochar pore sizes multiplied by factor 0.5. The detected pore size distribution of biochar does not predict directly (1:1 compatibility) the changes observed in the soil moisture characteristics. It is likely that biochar chemistry and pore morphology affect biochar-water interactions via e.g. surface roughness and contact angle.

Six-week old strawberries (Fragaria ananasa, var. Chandler) were transplanted into 4.5 m(2) raised beds under a plastic tunnel structure measuring 9.14 x 14.6 x 3.6 m. Vermicompost were applied at rates of 5 or 10 t ha(-1) supplemented with inorganic fertilizers to balance fertilizer recommendations for strawberries of 85-155-125 kg NPK ha(-1).

Organic C increased in the order ammonium nitrate>calcium nitrate>ammonium sulphate, whereas the increase in N followed the order ammonium nitrate>ammonium sulphate>calcium nitrate.

Excluding grazing livestock is considered as an alternative to restore vegetation in degraded sandy grassland in this region. However, few data are available concerning the impacts of continuous grazing and livestock exclusion on soil properties. In this paper, characteristics of vegetation and soil properties under continuous grazing and exclusion of livestock for 5 and 10 years were examined in representative degraded sandy grassland. Continuous grazing resulted in a considerable decrease in ground cover, which accelerates soil erosion by wind, leading to a further coarseness in surface soil, loss of soil organic C and N, and a decrease in soil biological properties. The grassland under continuous grazing is in the stage of very strong degradation. Excluding livestock grazing enhances vegetation recovery, litter accumulation, and development of annual and perennial grasses. Soil organic C and total N concentrations, soil biological properties including some enzyme activities and basal soil respiration improved following 10-year exclusion of livestock, suggesting that degradation of the grassland is being reversed. The results suggest that excluding grazing livestock on the desertified sandy grassland in the erosion-prone Horqin region has a great potential to restore soil fertility, sequester soil organic carbon and improve biological activity. Soil restoration is a slow process although the vegetation can recover rapidly after removal of livestock. A", "keywords": ["2. Zero hunger", "13.

Although sequestration of SOC through aforestation or reforestation proved favorable, these measures are restricted by the ability to produce rapid, cost-effective and precise sampling schemes. The aim of this study is to contribute to a better knowledge of the spatial distribution of soil C in tropical natural and plantation forest. This paper presents sampling strategies for estimating mean SOC values as well as for SOC mapping, based on different methods for SOC determination and on different precision levels. To do so we conducted a carbon variability study in five common forest types of Southeastern Tanzania (coastal dry forest, Miombo woodland, teak plantation, pine plantation and cashew plantation) using conventional statistical methods, as well as geostatistics. In the 5 forest types of this study, SOC stocks in the upper 5\u00a0cm ranges between 5 (in the cashew plantation) and 13 (in the coastal forest)\u00a0t ha\u2212\u00a01. The optimal sampling distance for measuring mean SOC stocks varies between 36\u00a0m (in the patchy miombo woodland) and 422\u00a0m (in the homogenized cashew plantation). Sample sizes fluctuate between 6 and 72 (1\u00a0t ha\u2212\u00a01 precision) for respectively cashew plantation and coastal forest. A rectangular grid with a sample interval of 25\u00a0m can be used for SOC mapping with a point kriging estimation error of 3.0\u00a0t ha\u2212\u00a01 in the coastal forest, 2.6\u00a0t ha\u2212\u00a01 in miombo woodland, 2.2\u00a0t ha\u2212\u00a01 in the teak plantation and 1.1\u00a0t ha\u2212\u00a01 in the cashew plantation. Since the pine plantation has no spatial structure; samples can be arranged randomly and its best soil map has an average C content attributed over the whole field. Refining the sampling strategy with a new spatial variability study in other forest types can be based on a regular grid with sampling distances of half the range identified in this study. This paper proves that the optimal sampling scheme varies strongly as a result of the different spatial behavior of SOC in forests and depends on the required precision and research question. Only when the right strategy is followed, high standards of precision can be met without economic loss or risk of statistical misinterpretation.", "keywords": ["0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.

To this end, a pair-wise comparison of neighbouring burned and unburned soils was carried out and complemented by laboratory heating experiments to clarify the role of fire intensity. In total, 18 pairs of adjacent burned and unburned pine forest soils were sampled within one month after wildfire. At each site, five samples were collected of the top 5\u00a0cm of the A horizon at randomly selected sample points and were mixed in the field to obtain one composite sample per site. Three additional samples were collected at each site but stored separately, and those of three sites were selected for the laboratory heating experiments. Laboratory heating involved five different temperatures ranging from 25 to 460\u00a0\u00b0C. Aggregate stability of the field and laboratory samples was determined using the water drop impact test, organic carbon content using a modified Sauerlandt method and soil water repellency using the \u2018Molarity of an Ethanol Droplet\u2019 test. The wildfire effects on field aggregate stability were highly variable and results indicated that these changes depend primarily on organic matter combustion and, thus, fire intensity. Controlled heating up to 220\u00a0\u00b0C either did not alter aggregate stability or increased it with increasing temperature, possibly due to the development of a protective coating of organic compounds inducing water repellency. Heating at 380 and 460\u00a0\u00b0C, by contrast, produced considerable to massive combustion of organic matter and, thereby, very pronounced reduction of aggregate stability as well as water repellency.", "keywords": ["Water repellency", "0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "Wildfire", "15.

Since 1999, the program of qGrain for Greenqhas been implemented in the semi-arid Loess Plateau, China. Its scope represents the largest vegetation restoration activity in China. However, it is still unclear for the SOC sequestration effects of vegetation cover change or natural succession promoted by the revegetation efforts at different scales under the semi-arid conditions. In this study, the changes in SOC stocks due to the vegetation restoration in the middle of Loess Plateau were estimated at patch, hill slope transect and small watershed scale from 1998 to 2006. Soil samples were taken from field for the determination of cesium-137 ((137)Cs) and SOC contents. Vegetation cover change from 1998 to 2006 at the small watershed scale was assessed using Geographic Information System. The results showed that cropland transforming to grassland or shrubland significantly increased SOC at patch scale. Immature woodland, however, has no significant effect. When vegetation cover has no transformation for mature woodland (25 years old), SOC has no significant increase implying that SOC has come to a stable level. At hill slope scale, three typical vegetation cover patterns showed different SOC sequestration effects of 8.6%, 24.6%, and 21.4% from 1998 to 2006, and these SOC increases mainly resulted from revegetation. At the small watershed scale, SOC stocks increased by 19% in the surface soil layer at 0-20 cm soil depth from 1998 to 2006, which was equivalent to an average SOC sequestration rate of 19.92 t Cy(-1) km(-2). Meanwhile. SOC contents showed a significant positive correlation (Pl0.001) with the (137)Cs inventory at every soil depth interval. This implied significant negative impacts of soil erosion on SOC sequestration. The results have demonstrated general positive effects of vegetation restoration on SOC sequestration at multiple scales. However, soil erosion under rugged topography modified the spatial distribution of the SOC sequestration effects. Therefore, vegetation restoration was proved to be a significant carbon sink, whereas, erosion could be a carbon source in high erosion sensitive regions. This research can contribute to the performance assessment of ecological rehabilitation projects such as qGrain to Greenq and the scientific understanding of the impacts of vegetation restoration and soil erosion on soil carbon dynamics in semi-arid environments.

We investigated whether grazing leads to deterioration of soil physical properties that subsequently increases topsoil erodibility. We sampled three sites (an ungrazed grassland, a continuously grazed grassland, and a track trampled by stock) on the northern Loess Plateau of China. The bulk density, water content, proportion of stable aggregates, infiltration rate, and resistance to scouring were determined for each soil sample. The results showed that the track had the highest soil bulk density and the lowest soil water content, proportion of stable aggregates, infiltration rate, and ability to resist scouring. The ungrazed plots had the best results for these parameters, in terms of reduced erosion. Soil bulk density and the proportion of stable aggregates differed significantly with depth beneath the track. However, the effect of depth on water content, infiltration rate, and the soil resistance to scouring was not significant at any sampling site. The ability of the soil to resist scouring was negatively correlated with the soil's bulk density and positively correlated with the soil's water content, infiltration rate, and proportion of stable aggregates. Thus, soil physical properties played an important role in determining soil erodibility. Grazing and trampling by livestock therefore appear to cause deterioration of soil physical properties and to increase soil erodibility.", "keywords": ["2.

Hence, suitable land uses for a climatic condition are expected to sequester optimum atmospheric carbon in soils. But, information on how climatic conditions and land uses influence carbon accumulation in the soils on the Himalayan Mountains is not known. This study reports the impact of four climatic conditions (sub-tropical, altitude: 500\u20131200\u00a0m; temperate 1200\u20132000\u00a0m; lower alpine 2000\u20133000\u00a0m; upper alpine, 3000\u20133500\u00a0m) and four land uses (forest, grassland, horticulture, agriculture) on the concentrations and stocks of soil organic carbon (SOC) in upper (0\u201330\u00a0cm) and deeper (30\u2013100\u00a0cm) soil depths on the western Himalayan Mountains of India. The study also explored the drivers which influenced the SOC stock build up on the mountains. Rainfall and soil moisture showed quadratic relations, whereas temperature declined linearly with the altitude. SOC stock as well as concentration was the highest (101.8\u00a0Mg\u00a0ha \u2212\u00a01 in 0\u201330\u00a0cm, 227.97\u00a0Mg\u00a0ha \u2212\u00a01 in 0\u2013100\u00a0cm) in temperate and the lowest in sub-tropical climate (37\u00a0Mg\u00a0ha \u2212\u00a01 in 0\u201330\u00a0cm, 107.04\u00a0Mg\u00a0ha \u2212\u00a01 in 0\u2013100\u00a0cm). Pattern of SOC stock build up across the altitude was: temperate\u00a0>\u00a0lower alpine\u00a0>\u00a0upper alpine\u00a0>\u00a0sub-tropical. SOC stocks in all land uses across the climatic conditions, except agriculture in lower alpine, was higher (0.7 to 41.6%) in the deeper than upper soil depth. SOC stocks in both the depths showed quadratic relations with soil temperature and soil moisture. Other factors like fine soil particles, land-use factor and altitude influenced positively whereas slope and pH, negatively to the SOC stocks. In all climatic conditions, other than temperate, SOC stocks were greater in natural ecosystems like forests and pastures (112.5 to 247.5\u00a0Mg\u00a0ha \u2212\u00a01 ) than agriculture (63 to 120.4\u00a0Mg\u00a0ha \u2212\u00a01 ). In temperate climate, SOC stock in agriculture (253.6\u00a0Mg\u00a0ha \u2212\u00a01 ) on well formed terraces was a little higher than forest (231.3\u00a0Mg\u00a0ha \u2212\u00a01 ) on natural slope. These observations, suggest that land uses on temperate climate may be treated as potential sinks for sequestration of the atmospheric carbon.

In natural or quasi-natural conditions a reduction in biomass increases the risk of erosion, and can reduce the stored soil organic matter content. This can cause (i) consolidation of low levels of organic carbon stored in the soil; (ii) reduction in the levels of organic carbon because of the onset of erosion processes; and (iii) differing rates of recovery of the soil in response to environmental factors including precipitation, which is a principal agent of indirect recharge of soil organic matter. Few comparable studies have analyzed the reduction of SOC because of erosion, and assessed how this contributes to the loss of soil as vegetation cover decreases. This is particularly the case in semiarid Mediterranean environments, where erosion is one of the main causes of soil degradation. This study presents the results of an experiment carried out along a pluviometric gradient from humid to semiarid Mediterranean conditions, in southern Spain. The study involved two soil depths at five field sites having similar lithology, slope and aspect, but differ in vegetation cover and composition related to their location along the gradient. We used soil cation exchange capacity (CEC) as an indicator of soil degradation. The results showed that: a) SOC decreased with decreasing rainfall; b) SOC is greater at the soil surface than at depth; c) CEC is a good indicator of the degradation of soil surface formations, as it is directly related to the SOC storage capacity; and d) the so-called \u201cMediterranean mountain\u201d landscape, with sparse and mixed vegetation composed of scrubland and woodland species, is a good organic carbon sink with direct implications in relation to climate change.", "keywords": ["2.

The wettability of ash, which can vary from highly absorbent to water repellent, is an important characteristic in this context. Recent work has suggested that ash wettability is related to its degree of combustion, which in turn, can be expected to determine ash chemical composition. In this paper we therefore examine the relationship between ash water repellency and ash chemical composition. Ten ash samples with different wettability were each taken from four burned Mediterranean forest sites located at Albaida (A), Lliber (L), Navalon (N), and Pinoso (P), in the east of Spain. The persistence of water repellency of samples was assessed by the Water Drop Penetration Time (WDPT) test and Fourier Transform-Infrared (FT-IR) analysis was applied to characterise sample chemical composition. Ash water repellency varied from wettable to severely water repellent and differed in terms of maximum WDPT and number of water repellent samples within the four locations. In all FT-IR spectra obtained, the absorbance bands assigned to organic matter and carbonates were dominant. They are subject to change during progressive combustion. The ratios of relevant peak areas were calculated, i.e. between aliphatic bands in the 3000\u20132800\u00a0cm \u2212\u00a01 region, other organic matter bands in the 1800\u20131200\u00a0cm \u2212\u00a01 region, and of the calcite band at 875\u00a0cm \u2212\u00a01 . These ratios are related to organic matter and calcite contents in ash samples and proved to be closely linked to the measured WDPT values through an exponential relationship. Organic matter content in all water repellent ash samples was more than twice the carbonate content. From the results obtained it is concluded that the water repellency or wettability of wildfire ash is driven by the ratio of remaining organic matter to emerging carbonates, which in turn, is related to fire severity.", "keywords": ["13.

The Apolobamba Integrated Management National Area is located in the Northwest of La Paz (Bolivia). This grassland ecosystem, with a high biodiversity, is a natural habitat of camelid populations, such as vicuna ( Vicugna vicugna ), a wild endangered species, and alpaca, a domestic camelid. There is not much information related to carbon reservoirs and camelid influence in these ecosystems. The objectives of this study were to (i) quantify total SOC contents as well as its quality by applying 13 C CP/MAS-Nuclear magnetic resonance spectroscopy, and (ii) determine the degree in soil exhaustion in selected zones on the basis of the degradation of SOM, related to vicuna and alpaca populations in Apolobamba. The vicuna densities were considered to select the studied zones as well as other characteristics. The goals of this research were achieved through the analyses of soil organic carbon quantity in soil profiles and in sampling plots. Likewise the 13 C CP/MAS-Nuclear magnetic resonance technique was used to gain information about soil carbon quality. Based on Total Organic Carbon contents and functional carbon groups we classified the area into three groups: 1) High, with O-Alkyl-C (50\u2013112\u00a0ppm) contents between 44% and 41% (zones 8, 4, 5, 7, 2 and 6), 2) Medium, 39% (zone 1), and 3) Low, 36% (zone 3). These results and the Alkyl-C/O-alkyl-C ratios (above 0.7) indicated Soil Organic Matter with a low stabilization. Overall Nuclear Magnetic Resonance spectra pointed out that the degradation of Soil Organic Matter was higher in zones 1 and 3 than in other studied areas in connection with high alpaca concentration.

In this case study, a paired-site approach was used to determine the differences in the SOC and SIC stock in the topsoil and subsoil, respectively, between a black locust (Robinia pseudoacacia L) forest site (converted from cropland 30 years ago) and a cropland site in the middle of the Loess Plateau of China. Compared with the cropland, the SOC stock was significantly greater under the forest in both the top 20 cm and the subsoil (30-60 cm layer). The annual litter input under the forest was more than twice that of the cropland, and the fine root biomass was significantly higher in the forest. We conclude that the higher litter input and fine root biomass may partly contribute to the greater SOC in the forest. In addition, the soil nitrogen (N) content changed in synchronicity with SOC during afforestation, which indicates that SOC accumulation in the top/subsoil may be determined by the increase in soil N in these layers. In contrast, the SIC stock in the top 20 cm of the forest was significantly lower than that of the cropland. However, this decrease in the SIC level in the topsoil of the forest was offset by an increase in SIC in the subsoil (60-100 cm). The change in SIC along the soil profile following afforestation could be explained by the dissolution and leaching of SIC from the topsoil and subsequent precipitation in the subsoil. The dissolution and leaching of SIC in the forest topsoil were due to the high biological activity associated with the high aboveground litter input, fine root biomass and SOC stock as well as the high soil water content, whereas the precipitation of the leached SIC in the subsoil was a result of the dramatic decrease in the soil water content and fine root biomass in the subsoil. These findings suggest that soil can accumulate organic carbon in the topsoil and subsoil following black locust plantation establishment on cropland (as in the Loess Plateau study area) and that this type of cropland to forest plantation conversion in this area can redistribute SIC along the soil profile without affecting the net SIC accumulation.

Although wheel tracks cover only a small portion of the surface of agricultural fields, their effect on surface runoff and sediment transport is substantial. Wheel tracks change the microrelief of the soil surface, and influence how the surface is further altered by rainfall and runoff. This study presents a plot-scale microrelief analysis of a tilled surface with wheel tracks under simulated rainfall. Digital elevation models of the microrelief with 1 cm spatial resolution were obtained using the Structure from Motion method. The random roughness, the structural connectivity, and functional connectivity were calculated for before-rainfall and after-rainfall soil surface conditions. The experiments were carried out on inclined, freshly-tilled plots (8 m long, 2 m wide). The wheel tracks were created by four passages of machinery in the slope direction (SWT) and in the contour-line direction (CWT). The experiments were compared to reference plots without wheel tracks (NWT). The wheel tracks increase water and sediment connectivity if they are oriented in slope-wise direction. Microrelief analysis shows that SWT drains water from the surrounding soil. The soil surface adjacent to SWT can also become more connected with the wheel track, due to changes in microrelief introduced by rainfall and runoff. The calculated higher connectivity in the SWT plot corresponded to the measured increased sediment loads. This suggests faster overland flow and therefore shorter flow pathways on the soil surface microrelief. CWT leads to a decrease in the water and sediment connectivity compared to the NWT and SWT plots. Although the surface runoff can overflow the CWT, the network of flow paths results in decreased flow velocity and a slower sediment transport rate. However, the CWT effect is not permanent, and declines as the wheel tracks become silted with the deposited sediment. It is shown that detailed microrelief data provide relevant information for a study of the changes in flow routing in a tilled agricultural field with the presence of a wheel track. SWT accelerates the runoff and especially the sediment transport. During a rainfall event, the hydraulic connection between the wheel track and the surrounding soil increases dramatically. CWT reduces the surface runoff and also the sediment transport. In the long term, rainfall events and surface runoff alter the microrelief connectivity, causing the soil surface to be more hydraulically connected, irrespective of the wheel track orientation. This study demonstrates the effect of wheel tracks on water and sediment transport. The results draw attention to the importance of appropriate soil protection measures, as a bare unprotected surface microrelief exposed to rainfall leads to increased sediment connectivity.

Nonetheless, the stabilization of soil organic carbon (SOC) and its fractions in these regions is largely unknown. The objectives of this study were to examine the changes in SOC and its fractions along a latitudinal gradient and to analyze the influencing factors in the southern margin of the permafrost region on the Eurasian continent. Topsoil (0-20 cm) was collected from five wetlands along a latitudinal gradient in Northeast China. We analyzed SOC and some labile fractions. Our results demonstrated that wetland SOC and its labile fractions concentration declined with decreasing latitude. The Permafrost regions had greater organic carbon content than the regions with seasonally frozen ground. The light fraction organic carbon and particulate organic carbon accounted for 5-83% and 21-32%, respectively, of the SOC and were particularly enriched in the permafrost region. Microbial biomass carbon and dissolved organic carbon showed a similar decreasing trend to that of SOC. At the same latitude, vegetation affected SOC stock and the dynamics of its labile fractions. Therefore, wetlands in mid-high latitudes contain a large carbon pool, and carbon stock varies with latitude. Although the labile fractions were higher in the permafrost region, their activities were lower, due to low temperature and poor nutrient status. Under global warming, the labile carbon pool may be mobilized and contribute to the greenhouse effect. Moreover, vegetation differences should be considered in obtaining an accurate carbon calculation.", "keywords": ["13.

Soil organic carbon age, accumulated carbon stock, and carbon source were determined on pyrolysis volatile (Py-V) and pyrolysis residue (Py-R) fractions of soil organic matter. Stable carbon isotopic composition of soil organic matter was also determined.

We investigated the effects of long-term (19\u00a0years) land use and fertilization on soil microbial community structures in a Luvisol soil. The experiment involved seven treatments: four cropping treatments containing no fertilizer (CK), recycled manure (RM), fertilizers nitrogen (N)\u00a0+\u00a0phosphorus (P)\u00a0+\u00a0potassium (K) (NPK), NPK\u00a0+\u00a0RM, and three no-crop treatments including bare land, mowed fallow, and non-mowed fallow. Methods The biomass and community composition of microbes in this soil were analyzed by phospholipid fatty acid (PLFA) and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) approaches. Results Our results showed that the microbial PLFA concentrations were significantly affected by different land use types, and decreased in the order of non-mowed fallow\u00a0>\u00a0mowed fallow\u00a0>\u00a0four cropping treatments\u00a0>\u00a0bare land. Although no significant difference was observed in the microbial PLFA concentrations among four cropping treatments, we found that manure application promoted microbial growth, while mineral fertilization suppressed it. PCR-DGGE profiles revealed that fungal community structures were more significantly alerted by long-term land use and fertilization than bacterial community. Conclusions Overall, we concluded that different land use types exerted greater impacts on soil microbial biomass and community structures than fertilization regimes in the Luvisol soil. Moreover, the changes of microbial biomass and community structures mainly resulted from differences in soil total C and N contents.", "keywords": ["2.

One land use that is particularly associated with the highest rates of erosion in Spain is extensive vineyards. We examined the effectiveness of two cover crops for improving soil physical properties and reducing erosion in a vineyard located in the Henares River basin southeast of Madrid, Spain. We assessed erosion from three replicate plots of 2\u00a0m 2 each with three treatments that comprised: traditional tillage, permanent cover of Brachypodium distachyon and spring-mown crop of Secale cereale . Erosion plots under traditional tillage yielded substantially more erosion (5.88\u00a0t\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 ) than Brachypodium (0.78\u00a0t\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 ) or Secale (1.27\u00a0t\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 ). While the concentration of SOC in sediments was greater for the cover crops, the mass-corrected loss of SOC was greater under tillage (0.06\u00a0t\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 ) than under Brachypodium or Secale (0.02\u00a0t\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 ). Root biomass was two- to four-times greater under the vegetation treatments. Our measure of aggregate stability for the tillage treatment remained between 7.9 and 5.4 drops over the four years of study and values for both cover crops exceeded that for Tillage by the end of the second year. The vegetation cover treatments increased SOC by 1.2% and intrapedal SOC by 10\u201360% compared with Tillage. By the end of the study, steady-state infiltration in the cover treatments was 45% greater than that under tillage, with the largest increase under Brachypodium . We attribute the greater infiltration on cover treatments to a greater abundance of larger pores on vegetated compared with tilled plots. Our study reinforces the notion that there are considerable benefits of using cover crops in rainfed vineyards, not only for prevention of soil erosion, but to enhance soil condition and potentially reduce the heavy reliance on industrial fertilisers.", "keywords": ["2.

This study evaluates the influences of biochar made from the waste wood of white lead trees (Leucaena leucocephala (Lam.) de Wit) on the physicochemical and biological properties of long-term cultivated, acidic Ultisol. This study used three application rates (0%, 2.5%, and 5% (wt/wt)) of the biochar with an incubation time of 105d for all cases. Soils were collected at 21d, 42d, 63d, 84d and 105d during the incubation period to evaluate changes in soil properties over time. A simulated rainfall event (80mmh\u22121) was performed to estimate soil loss for all treatments at the end of the incubation time. Experimental results indicate that applying biochar improved the physicochemical and biological properties of the highly weathered soils, including significant increases in soil pH from 3.9 to 5.1, cation exchange capacity from 7.41 to 10.8cmol (+) kg\u22121, base cation percentage from 6.40 to 26.0%, and microbial biomass carbon (MBC) from 835 to 1262mgkg\u22121. Compared with the control (i.e., no biochar), biochar application decreased bulk density from 1.4 to 1.1Mgm\u22123, increased Ksat by 1.8 times and increased the mean weight diameter (MWD) of soil aggregates from 2.6cm to 4.0cm. Incorporating biochar into the soil significantly reduced soil loss by 50% and 64% at 2.5% and 5% application rates, respectively, compared with the control. The formation of macroaggregates in the biochar-amended soils is the critical factor to improve soil erosion potential.

Earthworms are among the most important soil dwelling invertebrates. Their activity affects both biotic and abiotic soil properties, in turn affecting plant growth. Yet, studies on the effect of earthworm presence on crop yields have not been quantitatively synthesized. Here we show, using meta-analysis, that on average earthworm presence in agroecosystems leads to a 25% increase in crop yield and a 23% increase in aboveground biomass. The magnitude of these effects depends on presence of crop residue, earthworm density and type and rate of fertilization. The positive effects of earthworms become larger when more residue is returned to the soil, but disappear when soil nitrogen availability is high. This suggests that earthworms stimulate plant growth predominantly through releasing nitrogen locked away in residue and soil organic matter.

In this report, we explored conversion of water hyacinth (Eichornia crassipes) to biochar as a sustainable weed management strategy, as it also has potential for improving soil quality. Eichornia biomass samples were carbonised with limited supply of air in a muffle furnace at varied temperature (200 to 500\u00a0\u00b0C) and residence time (30 to 120\u00a0min). The biochar yield decreased with temperature and time, but biochar carbon stability increased with temperature.

TGA and FTIR studies showed that EBC has increased aromaticity and carbon stability compared to the starting biomass. Impact of the EBC on soil quality was studied using a red soil, from Dhanbad, India. Soil biochemical properties (dehydrogenase, fluorescein hydrolases, catalase, respiration, active microbial biomass) and maize seedling growth were used to investigate the effects of biochar addition to the soil. Maize seedling vigour index increased from 1.0 at control to 1.61 in 20\u00a0g/kg EBC treatment. The maximum increase in soil enzymes like acid phosphatase activity (+\u00a032%), alkaline phosphatase activity (+\u00a022.8%), and fluorescein hydrolases activity (50%) occurred at the EBC dose of 20\u00a0g/kg. EBC significantly enhanced the soil biological activity particularly the active microbial biomass which has increased by 3 times and soil respiration by 1.9 times.

Both MOC C sequestration efficiency (CES) and C sequestration distribution (CSD) were the highest among the C fractions for all the treatments. Significantly positive linear correlations were observed between accumulated C sequestrations in all fractions with gross C input and both maize and wheat yields.

We made assessments of selected soil properties according to the data during the sowing\u2013germination period of winter wheat only in 2012 autumn. Therefore, the number of germinated seedlings of winter wheat was also evaluated. The data of this study carried out in three replications were statistically analyzed using the ANOVA and the regression technique. The results indicated that the tillage treatments affected soil properties and wheat germination. The highest values in all examined parameters except for total porosity were obtained under the no-till practice for top soil layer of 30\u00a0cm. As was expected, the no-till treatment had the highest bulk density and provided the lowest total porosity. Generally, the plots tilled by conventional practice had the lowest values. Similar results were obtained for the top soil layer of 0\u201310\u00a0cm, which is seedbed. The penetration resistance measured to a depth of 30\u00a0cm in 5\u00a0cm increments increased as polynomial with increasing the soil depth in all treatments. The infiltration rate decreases as a function of elapsed time could be described by the Kostiakov equation. Also, significant linear relationships were obtained for penetration resistance\u2013bulk density, field capacity\u2013bulk density and field capacity\u2013penetration resistance. Although no-till treatment improved the hydraulic properties of soil, it had no positive effect on the soil physical properties. However, the linear relations with high correlation coefficients between penetration resistance and bulk density with field capacity at the no-till showed that soil physical and hydraulic properties revealed that they are connected to each other. According to the results of our study it could be concluded that the no-till practice increased winter wheat germination due to higher water content.", "keywords": ["2.

After 372\u00a0days, the incubated soils were analyzed for total organic C (TOC), potassium permanganate oxidizable C (POXC), light fraction organic C (LFOC), water soluble organic C (WSC), hot-water extractable C (HWC) and microbial biomass C (MBC), macroaggregates (>\u00a00.25\u00a0mm), dehydrogenase, \u03b2-glucosidase and urease. The highest macroaggregates, POXC, LFOC, HWC, MBC and enzyme activities were measured in the lowest rates (W 0.5 and B 0.5 ). MBC positively correlated with all labile organic C and macroaggregates, indicating that microbial activities result in mineralization of organic matter (OM) and contribute on bonding agent for macroaggregation. The C/N of the experimental soil negatively correlated with most of labile organic carbons and macroaggregates, which could be the effect of limited N availability on labile organic carbon fraction and aggregation. As compared to the control, lability index (LI) (changes in the lability of soil carbon) increased in W 0.5 and B 0.5 by 4 and 6%, respectively, whereas the carbon management index (CMI) (changes of the total carbon in the soil and its lability) increased by ranges of 50 to 286% in the treatments, and implies sequestration of organic C in soil. The high CMI is largely caused by high C sequestration and low lability differences between the treatments. Our results suggest that biochar application increases total organic carbon, stimulates microbial activities, in turn increases macroaggregation, and thus soil quality.", "keywords": ["2.

Documentation of ash layer characteristics, specifically ash sorptivity and hydraulic conductivity, is instrumental to understanding and modeling post-fire environments and infiltration response. The aim of this study was to evaluate laboratory methodologies for determining ash hydraulic conductivity and sorptivity based on established methodologies from soil measurements. A series of field and laboratory tests were conducted on ash from 13 high severity wildfires within western North America to evaluate; i) a non-destructive method for the rapid assessment of saturated hydraulic conductivity in the laboratory, ii) a method for directly measuring ash sorptivity in the laboratory and iii) compare these laboratory methods, conducted on disturbed samples, to field measurements taken in-situ. The air permeametry method and the use of a sorptivity probe are viable methodologies for obtaining ash saturated hydraulic conductivity and sorptivity values respectively in the laboratory. Air permeametry was non-destructive, allowing ash samples to be further processed, while the sorptivity probe provided a direct measurement of sorptivity as values were collected with no gravitational component. Results were consistent between laboratory- and field-based methodologies, indicating that disturbed laboratory readings are a viable substitute for in-situ field measurements when pertaining to ash sorptivity and hydraulic conductivity.

Few studies have examined harvest impacts on soil chemistry in conifer forests which have not been significantly affected by acid deposition, as found on the Canadian West Coast. This study investigates the effects of conventional clear-cutting on soil chemistry in Podzols of Roberts Creek Study Forest (southwestern Canada). We measured forest floor composition, soil pH and salt-extractable ions concentrations in undisturbed forested stands (control plots), stands harvested 2 to 5\u00a0years prior to sampling (cleared plots) and stands harvested 8 to 15\u00a0years prior to sampling (regenerating plots). We focused on the effects of forest harvest both on mean (differences in average values) and dispersion parameters (differences in variance between treatments). We found that forest floors of harvested plots had lower phosphorus and potassium concentrations than control plots. In the mineral subsoil, exchangeable K was however higher in harvested than in control plots. This suggests that some of the K lost from the forest floor was preferentially retained in mineral horizons, possibly due to sorption to poorly crystalline and free aluminum and iron mineral phases. The subsoil of harvested plots was slightly more acidic than control plots. In contrast to classic studies of forest harvest impacts conducted in the U.S. Northwest, we did not measure pronounced acidification, a loss of base cations or an increase in exchangeable Al, most likely due to the much lower prior acid deposition load at our sites. The most notable harvest effect was a large increase in the variability of inorganic N concentration. This suggests an increase in micro-heterogeneity of post-harvest nutrient availability which has implications for the nutrition of regenerating vegetation, nutrient leaching potential as well as our ability to detect harvest-induced changes.", "keywords": ["0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.

Rich (Lebanon cedar) on bare land in the semi-arid Nigde Akkaya dam watershed for erosion control and green belt creation. Soil samples were collected from three land use types (Black Pine planted, Lebanon cedar planted area and bare land) at two soil depths (0\u201310\u00a0cm and 10\u201320\u00a0cm) and replicated three times.

Generally, soil organic carbon was observed to increase after afforestation. Soil organic carbon (SOC) values were 1.09% and 1.13% in Black Pine and the Cedar area, respectively. These values were significantly higher than the values for the bare land soils (0.54%). For all types of land use, the amount of SOC in the soils decreased with depth.
