Other claims from this paper (19)
- Association Including cover crops in the cropping system may alter soil enzyme activities and the richness of the soil microbial community, depending on the duration of the cover crop.
- Intervention effect Long-term (20-year) winter rye cover crop increased water-extractable C and N content, B-glucosidase and urease relative to no cover crop.
- Intervention effect Long-term (20-year) winter rye cover crop increased acid phosphatase, alkaline phosphatase and arylsulfatase activities relative to no cover crop.
- Intervention effect Long-term (20-year) winter rye cover crop increased fluorescein diacetate activity and soil bacterial community abundance relative to no cover crop.
- Intervention effect Short-term winter rye, legume and brassica mixtures did not differ from no cover crop in soil microbial community abundance.
- Intervention effect Short-term (3-year) legume and grass cover crop mixture increased B-glucosidase, acid phosphatase and alkaline phosphatase activities relative to no cover crop.
- Intervention effect Short-term (3-year) legume and grass cover crop mixture increased arylsulfatase, FDA and total phospholipid fatty acid concentration relative to no cover crop.
- Intervention effect Diverse crop rotations had significant effects on corn root distribution and corn yield compared with the 2-year corn-soybean rotation.
- Intervention effect The CSSwP rotation had lower corn root biomass, corn root length density and total root length density at anthesis than other rotations.
- Intervention effect The CSSwP rotation gave greater corn yield than other rotations.
- Intervention effect The CS rotation had lower corn yield than the other diverse crop rotations.
- Intervention effect The CS rotation had lower soybean yield than the other diverse crop rotations.
- Intervention effect Crop rotation showed no evidence of influencing crop grain nutrient storage.
- Intervention effect Crop rotation produced a slight difference in crop biomass.
- Intervention effect Diverse crop rotations provided more benefits in crop production and economic return than the CS rotation.
- Intervention effect The CS rotation required greater total input cost than the diverse crop rotations.
- Intervention effect Diverse crop rotations did not significantly increase corn yield compared with the CS rotation.
- Intervention effect The CS rotation significantly reduced soybean yield compared with the diverse crop rotations.
- Intervention effect The CS rotation was less resilient than diverse crop rotations in gross and net revenue when nitrogen fertilizer was applied below the rate needed for maximum yield.
