Other claims from this paper (15)
- Intervention effect Sulfur fertilization raised alfalfa sulfur concentration.
- Intervention effect Sulfur fertilization lowered alfalfa N:S ratio.
- Intervention effect Sulfur fertilization did not change corn grain or silage nutritive value.
- Intervention effect 134 kg S/ha increased alfalfa sulfur concentration.
- Intervention effect 134 kg S/ha decreased alfalfa N:S ratio approximately 9%.
- Intervention effect Sulfur fertilization did not change protein content in either crop.
- Intervention effect Sulfur fertilization did not change dry matter digestibility in either crop.
- Observation Sulfur sources generally did not differ significantly.
- Observation FBM was an effective sulfur source and contained 33% CaO.
- Intervention effect Alfalfa yield increases were significant only in year three at two locations.
- Intervention effect Year-three sulfur fertilization raised alfalfa yield up to 14% at Landisville.
- Intervention effect Alfalfa yield was lower at Rector and did not increase with sulfur.
- Intervention effect Sulfur fertilization did not improve corn grain yield.
- Intervention effect Sulfur fertilization did not improve corn silage yield.
- Association No sulfur by nitrogen interaction was found for corn yield.
