Spatial Changes in Glomalin-Related Soil Protein and Their Correlation with Soil Properties in the Black Soil Region of Northeast China

open access: yesAgronomy, 2022
Glomalin-related soil protein (GRSP), soil nutrients, and soil enzyme activities are closely related to soil fertility and land productivity, which play an important role in indicating soil quality. Little is known about the spatial variation in GRSP and

The Lower Boundary of Selected Mollisols [PDF]

open access: yesSoil Science Society of America Journal, 1967
Abstract Thicknesses of three Mollisols (Tama, Elburn, and Drummer series), developed from Wisconsinan‐age material in a toposequence in Central Illinois, were considerably greater (18 to 68 cm) when their lower boundaries were determined by the depth of rooting of native perennial big bluestem (

No-Tillage Improvement of Nitrogen Absorption and Utilization in a Chinese Mollisol Using 15N-Tracing Method

open access: yesAtmosphere, 2022
To better understand the mechanism of nitrogen (N) distribution, absorption, utilization and loss in fertilizer under different tillage practices, a study was conducted to quantitatively explore the fate of fertilizer N in the soil–plant–atmosphere using

Studies on dissipation of thiamethoxam insecticide in two different soils and its residue in potato crop

open access: yesPlant, Soil and Environment, 2014
The dissipation patterns of thiamethoxam insecticide at two different rates (12.5 and 25 µg/g) in both silty clay loam and loam soils were studied. The half lives of thiamethoxam were in the range of 15.0 to 18.8 days in silty clay loam and 20.1 to 21.5 ...

Water-Covered Depth with the Freeze–Thaw Cycle Influences Fungal Communities on Rice Straw Decomposition

open access: yesAgriculture, 2021
Rice is a staple food for the world’s population. However, the straw produced by rice cultivation is not used sufficiently. Returning rice straw to the field is an effective way to help reduce labor and protect the soil.
