Other claims from this paper (10)
- Intervention effect Tillage only did not suppress couch grass.
- Intervention effect Tillage only produced low barley nitrogen and phosphorus uptake.
- Intervention effect More nitrogen was immobilized in couch grass and microbial biomass under tillage only than under comparable herbicide rotations.
- Intervention effect Tillage plus herbicide suppressed couch grass.
- Intervention effect Tillage plus herbicide enabled barley competition for soil nitrogen.
- Recommendation Both spring and autumn tillage were required for weed control.
- Intervention effect Fallow reduced soil and microbial carbon and nitrogen.
- Intervention effect Fallow produced barley yields similar to continuous cropping with chemical control.
- Intervention effect Red clover green manure enhanced soil quality indicators.
- Intervention effect Red clover green manure did not increase barley yield compared with continuous grain cropping.
