  • Based on the the soil survey conducted in the late 1980s, the AA. sampled in the summer of 2007 : 17 sites of the tillage (A) layer soils and 13 sites of soil profiles, including the tillage and subsoil layers from 3 types of arable land soils
  • in Lhasa (alluvial soil, steppe soil, and meadow soil). At the same time, another 55 composite samples and core samples were taken from the grain-crop land, open vegetable land and greenhouse vegetable land of the alluvial soil. Selected soil properties
  • were measured and compared to the soil survey data from the 1980s. The results showed that because of wind erosion and irrigation, the arable soils have become significantly more sandy since the late 1980s. Moreover, because of fertiliser application
  • and acid precipitation, the soil pH and cation exchange capacity are significantly lower than in the late 1980s, thus leading to soil acidification and lower soil fertility. It is suggested that the changes in the soil properties were mainly due

  • To reduce uncertainties from upscaling spatial processes of the DeNitrification-DeComposition (DNDC) model for improving the definition of China's paddy soils SOC stocks (0-30 cm) and their changes from 1980 to 2008, a soil polygon-based modeling
  • method was developed by integrating DNDC with the latest 1:1,000,000 soil database, derived from 1490 paddy soil profiles collected during the Second National Soil Survey of China. There were, however, large regional differences in sequestration outcomes
  • . Increases in paddy soil SOC stocks were found predominantly in South, Eastern and Southwest China. Enhancement in the soil databases with higher resolution inputs should improve the C sequestration estimates of any area of interest.

  • Knowledge of soil water storage (SWS) within soil profiles is crucial when selecting appropriate practices for the restoration of vegetation. To study the temporal stability of SWS and identify representative locations in diverse soil layers
  • , an analysis of temporal stability was performed using Spearman rank correlation coefficients and relative differences. From July 2008 to October 2010, the SWS of 3 soil layers (0-1, 1-2, and 2-3 m) were measured using a neutron probe at 91 locations
  • on a hillslope on the Loess Plateau, China. The results showed that the variability of SWS decreased over time and increased over space with the increase in soil depth. With increasing soil depth, more locations were able to estimate the mean SWS of the area
  • . None, however, represented the mean values for all three soil layers separately.

  • Reflectance anisotropy for measuring soil surface roughness of multiple soil types
  • Aggregate ; Basel ; Cultivated land ; Data processing ; Geostatistics ; Remote sensing ; Roughness ; Soil ; Soil degradation ; Soil properties ; Spectral reflectance ; Switzerland
  • Five soil types with varying biochemical properties were subjected to artificial rainfall, producing a sequence of soil states of progressively declining soil surface roughness. Point laser data (2 mm sample spacing) were geostatistically analysed
  • to give a spatially-distributed measure of surface roughness. Hyperspectral Hemispherical Conical Reflectance Factors (HCRFs) from the soil states were measured using a ground-based hyperspectral spectroradiometer. A directional index (Anisotropy Measure
  • ; AM) was determined, using a ratio between extreme forward-scattered and backscattered HCRFs. Regression analysis of AM against a geostatistically-derived value of soil surface roughness (sill variance) was used to test the ability of the AM
  • for description of surface roughness for all soil types. The results demonstrate the great potential of this approach for compensating for spectral differences between different soil types.

  • This study examined the changes in soil properties and soil quality 30 years after cultivated farmland was restored back to forest land in Loess Plateau, China. Specifically, organic matter, total nitrogen (N) and phosphorus (P), available N, P
  • and Potassium (K) contents and enzyme activities in soils were tested and analyzed. The study showed that after 30 years of restoration, nutrients content in the soil of mixed forest of black locust and amorpha increased significantly. However, nutrients content
  • in the soil of mixed forest of Chinese pine and amorpha decreased. The study also found that the organic matter content was relatively low in the restored soils, compared with not-restored land. This may be caused by the high enzyme activity per unit
  • of organic carbon in the soils of the study area which tends to help decompose and therefore decrease the organic matter in soil.

  • The aim of this study was to elucidate the interrelationship between the spatial variability of soil respiration and the spatial variability of soil redistribution as well as other soil and crop properties. The study was carried out in a small
  • agricultural watershed subjected to water and tillage erosion processes. During three crop cycles (one of sugar beet, two of winter wheat) soil respiration, soil temperature, and soil moisture were measured in situ at least bi-weekly at 20–22 locations. Effects
  • of differences in soil temperature and moisture, erosional and depositional status, plant and soil properties were analysed. The results highlighted that : effects of spatial differences in soil temperature and moisture on soil respiration were marginal
  • ; Differences in median grain size and bulk density had the most consistent effect on soil respiration; During most measuring phases respiration was smaller at erosional compared to depositional sites.

  • In this paper, the AA. characterize the long-term effect of reforestation on the stabilization of soils affected by strong gully erosion in Prietrž village in South-Western Slovakia. Permanent gullies there were reforested a century ago
  • with the black locust (Robinia pseudoacacia). Reforestation measures induced soil profile development on the gully slopes with distinct humus horizons. The overall effect of the observed changes is an increase in the aggregate stability of these reforested gully
  • soils. The values determined for these gully soils do not differ significantly from those in the surrounding non-eroded agricultural soils. The extreme difference in aggregate stability between the topsoils and the parent marl material is responsible

  • Cultivated land ; Eastern United States ; Extreme event ; Precipitation ; Regional analysis ; Soil erosion ; Spatial analysis ; Time series ; United States of America
  • Alternatively, the AA. define extreme events as the largest events sorted by rank, whatever their absolute magnitude. The new approach applied to soil erosion is that, whatever the magnitude of soil eroded, erosion is a time compressed process
  • and the percentage contribution to total soil erosion by the few largest events (regardless of their magnitude) is negatively related to the total number of daily soil erosion events recorded. The AA. present here a geographical analysis of the effects of largest
  • daily event on soil erosion by comparing 594 erosion plots located in agricultural fields under various climatic temperate conditions across the central-east of the USA. It is shown that the n-largest events contribution not differ between regions of USA

  • In this study, the P and organic C content of sediment generated from 2 Devon silts under conventional (CS) and organic (OS) soil management were examined. Artificial rainfall was applied to the soils using 2 rainfall scenarios of differing
  • intensity and kinetic energy to determine the effects on the P and C enrichment in interrill sediment. Interrill soil erodibility was lower on the OS, irrespective of rainfall intensity. Sediment from both soils showed a significant enrichment in P and C
  • compared to the bulk soil. A comparison of soil and sediment properties indicates that crusting, P and C content as well as density and size of eroded aggregate fragments control P and C enrichment. Due to complex and dynamic interactions between P, soil
  • organic carbon (SOC) and interrill erosional processes, the nutrient and C status of sediments cannot be predicted based on soil P content, SOC or interrill erodibility alone.
