Microbial Community Composition as Affected by Dryland Cropping Systems and Tillage in a Semiarid Sandy Soil
This study evaluated microbial communities of soil (0–10 cm) as affected by dryland cropping systems under different tillage practices after 5 years. The soil type was an Olton sandy loam with an average of 16.4% clay, 67.6% sand and 0.65 g kg of organic matter (OM). The cropping systems evaluated were grain sorghum (Sorghum bicolor L.)— cotton (Gossypium hirsutum) (Srg-Ct), cotton-winter rye (...
متن کاملInteractions of tillage and soil depth on ̄uometuron degradation in a Dundee silt loam soil
Fluometuron (N,N-dimethyl-N0-[3-(tri ̄uoromethyl)phenyl]urea) is the most widely used soil applied herbicide in cotton (Gossypium hirsutum) production in the Southeastern United States. Thus, there is a need to understand the persistence of this herbicide under various crop management systems in regards to both herbicide ef®ciency and environmental fate. The effects of long-term no-tillage pract...
متن کاملTillage effects on soil organic carbon distribution and storage in a silt loam soil in Illinois
Interest in tillage impacts on sequestration of soil organic carbon (SOC) has increased greatly during recent years. The use of reduced and no-tillage (NT) practices generally increases the SOC concentration in surface few centimeters when compared to conventionally tilled soils. However, use of conservation tillage does not always result in increased SOC storage overall. The effects of sample ...
متن کاملQuantifying hysteresis of atrazine desorption from a sandy loam soil.
Batch experiments were carried out to investigate the effects of initial atrazine concentrations and consecutive desorption steps on the desorption characteristics of atrazine from a sandy loam soil. As initial atrazine concentration increased, the average percentage of atrazine desorption on the sandy loam soil ranged gradually from 23.1% to 38.5% after five consecutive desorption steps. The v...
متن کاملAssessment of chromium fixation capacity of sandy loam soil
The adsorption of chromium species in soils has received much attention because of its toxicity and bioavailabilities, which are adsorption depended. There are very little studies on adsorption of chromium in sandy loam soil. Hence, this paper presents the Cr adsorption capacity of sandy loam soil under chromium spiked condition. A batch technique was used to perform cr adsorption studies. Soil...
