Other claims from this paper (11)
- Intervention effect Growth increased as sulphur supply increased.
- Observation All but highest-sulphur plants showed deficiency symptoms.
- Association More severe sulphur deficiency increased the root share of the plant.
- Association More severe deficiency reduced stem and petiole proportions.
- Observation Lamina proportion fell only slightly under deficiency.
- Association Protein nitrogen percentage rose with sulphur supply.
- Association Total nitrogen percentage rose with sulphur supply.
- Association Protein nitrogen made up more total nitrogen at higher sulphur levels.
- Observation Protein sulphur was the bulk of total sulphur in deficient plants.
- Association Sulphate sulphur increased less as sulphur supply approached adequacy.
- Observation White clover differed from other legumes and non-legumes in the principal accumulated sulphur form.
