BACKGROUND Physico-chemical sorption onto soil minerals is one of the major processes of dissolved organic carbon (OC) stabilization in deeper soils. The interaction of DOC on soil solids is related to the reactivity of soil minerals, the chemistry of sorbate functional groups, and the stability of sorbate to microbial degradation. This study was conducted to examine the sorption of diverse OC ...

Artificial ecological corridors (AECs) are internationally approved restoration and climate mitigation strategies. The width recovery time indices of AECs directly affect the efficiency degraded soil nutrients. However, there is a lack comprehensive quantitative evaluation research on construction factors from perspective fertility improvement. This aimed to examine critical corridor affecting ...

BACKGROUND Understanding the nitrogen (N) mineralization process and applying appropriate model simulation are key factors in evaluating N mineralization. However, there are few studies of the N mineralization characteristics of paddy soils in Mollisols area of Northeast China. MATERIALS AND METHODS The soils were sampled from the counties of Qingan and Huachuan, which were located in Molliso...

the present study was carried out in kharkeh research station, kurdestan province, western iran to investigate the effects of the change in land use on the degradation of mol-lisols, their organic carbon content, clay mineralogy and k+ status. the study area was partly under cultivation (for over 40 years) and partly preserved as rangelands. the re-sults revealed that mollisols are the dominant...

Abstract The study was based on the distribution of soil carbon and nitrogen orders in a dryland farming system Aceh Besar District, Indonesia. Soil samples were taken to represent 6 (six) drylands Besar, namely: Andisols, Entisols, Inceptisols, Mollisols, Oxisols, Ultisols. For each order, 5 observation profiles made, profile sampled at 7 (seven) depths from 0-100 cm, 0-0.05 m; 0.05-0.10 0.10-...

Conversions of Mollisols from prairie to cropland and subsequent changes in crop production practices in the Midwestern USA have resulted in changes in soil organic matter. Few studies have used archived samples, long-term resampling of soils to a depth of 1 m, and space for time studies to document these changes. We resampled soils by depth (0-100 cm) in fields at 19 locations in central Illin...

In the highly fertile and productive soils of Pampa Region Argentina, constraints on soil water regime as a consequence decline in aggregates stability development platy structures, are observed. Most agricultural plots this region, even under no tillage, subjected to simplification crop sequences (low cropping intensity) with predominance soybean. On contrary, some farmers intensifying crops s...
