Other claims from this paper (11)
- Intervention effect Increasing soil oxygen had little effect on rye Ca or Mg content.
- Intervention effect Increasing soil oxygen raised rye K from 2 to 5%.
- Intervention effect Increasing soil oxygen raised rye K/(Ca+Mg) above 4.
- Association Uptake of K, Ca and Mg was generally lower at 12 than 16 C.
- Intervention effect Ryegrass K, Ca and Mg contents were higher with increasing soil oxygen.
- Association Ryegrass K, Ca and Mg concentrations were lower at 12 than 16 C.
- Intervention effect Soil oxygen had little effect on arrowleaf clover forage composition.
- Intervention effect Arrowleaf clover K increased slightly with soil oxygen.
- Association Ryegrass on poorly drained soil was inferred to be more tetany prone.
- Association Rye on well drained soil was inferred to be more tetany prone.
- Recommendation High clover Mg was judged valuable for balancing tetany prone grass forage.
