Persistence of Subsoil Compaction in a Mollisol

Soil Science Society of America Journal, 1976
Abstract Persistence of subsoil compaction was tested in Nicollet clay loam (a Mollisol) in southwestern Minnesota. Plots were either not packed or packed in 1960 in the bottom of each plow furrow using about 7.5 bars pressure, and were cropped to corn ( Zea mays L.) and ...

Fate of Benfuracarb Insecticide in Mollisols and Brinjal Crop

Bulletin of Environmental Contamination and Toxicology, 2009
The fate of benfuracarb was studied under field conditions in brinjal fruits and soil following foliar spray application at 0.25 and 0.50 microg g(-1) by HPLC. At 0.25 microg g(-1), benfuracarb persisted up to 7 days both in soil and brinjal but at 0.50 microg g(-1), benfuracarb residues persisted up to 10 and 12 days in soil and brinjal fruits ...

Kinetics of sorption‐desorption of benfuracarb insecticide in mollisols

Pest Management Science, 2010
AbstractBACKGROUND: Sorption‐desorption processes govern the movement of pesticides in soil. These processes determine the potential hazard of the pesticide in a given environment for groundwater contamination and need to be investigated.RESULTS: In the present study, sorption‐desorption processes of benfuracarb were investigated using a batch method ...

Long‐Term Changes in Mollisol Organic Carbon and Nitrogen

Journal of Environmental Quality, 2009
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)

The effects of freeze-thaw cycles at different initial soil water contents on soil erodibility in Chinese Mollisol region

, 2020
Freeze-thaw action is a common natural phenomenon in cold regions, which affects soil erodibility by changing soil structure and mechanical properties. However, quantifying the impacts of freeze-thaw cycles (FTCs) at different initial soil water contents

Mollisols properties and changes in Ukraine and China

Chinese Geographical Science, 2011
Soils are the foundation of civilizations and the basis for human food production. Mollisols in Ukraine and Northeast China are two out of the four major Mollisol regions in the world. The natural areas from which Mollisols developed are the prairies and steppes that experience temperate and freezing conditions. This review paper introduces the general

Soluble Organic Carbon in a Biosolids‐Amended Mollisol

Journal of Environmental Quality, 1999
AbstractOrganic matter can be mobilized from many sources and transported in soil by precipitation, snowmelt, and water table fluctuations. Knowledge of the potential fluxes of soluble organic C in different kinds of soil is essential to improve global C budgets.

Variations in the profile distribution and protection mechanisms of organic carbon under long-term fertilization in a Chinese Mollisol.

Science of the Total Environment, 2020
Long term fertilization may have a significant effect on soil organic carbon (SOC) fractions and profile distribution. However, previous research mostly explored the SOC in the topsoil and provided little or no information about its distribution in ...

Effects of maize straw and its biochar application on organic and humic carbon in water-stable aggregates of a Mollisol in Northeast China: A five-year field experiment

Soil & Tillage Research, 2019
In agricultural ecosystems, one optimized crop residue management practice, i.e., incorporating biochar produced from crop residues via pyrolysis to the soil, is considered a promising technology for mitigating climate change and improving soil quality ...
