Other claims from this paper (14)
- Intervention effect Undersown companion crops captured 31 to 42 kg/ha nitrate nitrogen and covered soil after maize harvest.
- Intervention effect Undersowing perennial ryegrass at 25 kg/ha reduced soil erosion by 13%.
- Intervention effect Undersowing perennial ryegrass at 50 kg/ha reduced soil erosion by 54%.
- Recommendation Red fescue appeared preferable as an early sown companion crop with limited maize competition.
- Recommendation Authors advise avoiding rape, field bean, pea and smooth-stalked meadowgrass as undersown species.
- Intervention effect Cover crops provided soil coverage before maize sowing.
- Intervention effect Cover crop residues slowed early-season soil warming.
- Association Younger cover crops were easier to destroy.
- Association Earlier cover crop destruction eased maize sowing.
- Intervention effect With early cover crop destruction, maize yields did not decrease.
- Observation Mixed ryegrass and radish cover crops were harder to destroy.
- Intervention effect Cover crops captured 40 to 70 kg/ha nitrate nitrogen between crops.
- Recommendation The authors advise adjusting subsequent mineral fertilizer dressings for cover crop organic matter.
- Intervention effect Side dressing allowed 35 to 45 kg N/ha less broadcast nitrogen without reduced yield, provisionally.
