Soil Microbial Indicators within Rotations and Tillage Systems

Long-term tillage effects on the distribution patterns of microbial biomass and activities within soil aggregates

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 (...

Soil Microbial Substrate Properties and Microbial Community Responses under Irrigated Organic and Reduced-Tillage Crop and Forage Production Systems

Changes in soil microbiotic properties such as microbial biomass and community structure in response to alternative management systems are driven by microbial substrate quality and substrate utilization. We evaluated irrigated crop and forage production in two separate four-year experiments for differences in microbial substrate quality, microbial biomass and community structure, and microbial ...

Tillage and crop residue effects on soil carbon and carbon dioxide emission in corn-soybean rotations.

Soil C change and CO2 emission due to different tillage systems need to be evaluated to encourage the adoption of conservation practices to sustain soil productivity and protect the environment. We hypothesize that soil C storage and CO2 emission respond to conservation tillage differently from conventional tillage because of their differential effects on soil properties. This study was conduct...
