Persistence of Subsoil Compaction in a Mollisol
Soil Science Society of America Journal, 1976Abstract 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 ...

Key factors influencing on vegetation restoration in the gullies of the Mollisols
Journal of Environmental Management, 2021Natural vegetation restoration (NVR) highly relates to the development of gully erosion, and is mainly determined by both the soil properties and species competition in the gullies. However, it is still not clear what are the key factors influencing on the vegetation restoration in the gullies with the poor soil properties (e.g. low soil organic matter

Fate of Benfuracarb Insecticide in Mollisols and Brinjal Crop
Bulletin of Environmental Contamination and Toxicology, 2009The 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, 2010AbstractBACKGROUND: 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 ...

Physical properties of a Mollisol, an Oxisol and an Inceptisol
Soil and Tillage Research, 1990Abstract An Inceptisol (Andept) from Ecuador, an OOxisol (Ustox) from Columbia and a Mollisol (Udoll) from the U.S.A. were studied. The clay in the Andept was >85% amorphous with allophane being predominant. The Ustox contained sesqui-oxides of iron and aluminum and kaolinite, while the Udoll contained hydrous mica, quartz and kaolinite in the clay ...

Fractionation of Phosphorus in a Mollisol Amended with Biosolids
Soil Science Society of America Journal, 1999Information about soil P fractions is useful to predict the bioavailability of P in soil as well as to predict the likelihood of its transport. In this study, we used a sequential fractionation procedure to investigate the forms of P in a Mollisol amended at the soil surface with biosolids (i.e., anaerobically digested sewage ...

Hydric Soil Indicators in Mollisol Landscapes
2000Mollisols are mineral soils that usually develop under prairie vegetation. They are characterized by relatively thick, dark surface horizons resulting from an increased organic matter content, which can present problems for hydric soil identification due to the lack of visible iron-based redoximorphic features (Chapters 7 and 8) in the upper part of ...

Publisher Summary Mollisols are mineral soils that have a mollic epipedon (dark-colored surface horizon with greater than 50 % base saturation as determined by the ammonium-acetate method) or have a surface horizon that after mixing to a depth of 18 cm meets all requirements for a mollic epipedon except thickness. It also has an upper subhorizon that

Long‐Term Changes in Mollisol Organic Carbon and Nitrogen
Journal of Environmental Quality, 2009Conversions 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)

Soluble Organic Carbon in a Biosolids‐Amended Mollisol
Journal of Environmental Quality, 1999AbstractOrganic 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.
