Other claims from this paper (12)
- Intervention effect Weed residues inhibited growth more in silica sand than in soil and sand mixture.
- Intervention effect Incorporated residues inhibited growth 8 to 14% more than surface-applied residues.
- Intervention effect All residues except common ragweed reduced corn dry matter by 6 to 20%.
- Intervention effect All residues except common ragweed reduced soybean dry matter by 2 to 20%.
- Association Residue source, placement and soil texture conditioned N, P and K uptake responses.
- Intervention effect Supplemental N and P did not alleviate crop growth inhibition.
- Intervention effect Added P markedly enhanced P uptake.
- Intervention effect Added P did not affect total dry weight.
- Intervention effect Common ragweed residues increased corn K uptake by 21 to 48%.
- Intervention effect Yellow foxtail residues did not increase soybean K uptake.
- Intervention effect Common ragweed residues did not increase soybean K uptake.
- Mechanism The authors inferred allelopathic growth inhibition independent of N and P nutrition.
