- Intervention effect Vanadium failed to reverse established iron chlorosis and caused toxic symptoms.
- Intervention effect Reducing iron supply accentuated vanadium toxicity in soybean.
- Intervention effect Reducing iron supply accentuated vanadium toxicity in flax.
- Intervention effect A similar phosphorus reduction did not change vanadium toxicity in soybean and flax.
- Intervention effect Lowering phosphorus to one tenth increased pea toxicity when iron was high.
- Intervention effect Raising iron to 20 or 30 p.p.m. counteracted molybdenum toxicity.
- Intervention effect Raising iron to 20 or 30 p.p.m. counteracted vanadium toxicity.
- Intervention effect Small repeated iron doses were less effective against molybdenum or vanadium excess than fewer large doses.
- Intervention effect Varying iron had little effect when the three metals were low.
- Intervention effect Higher iron reduced shoot manganese and vanadium contents when it relieved chlorosis.
- Intervention effect High iron lowered shoot molybdenum only at non-toxic molybdenum combined with excess manganese.
- Intervention effect Shoot iron content changed little with iron supply.
- Intervention effect High manganese, molybdenum or vanadium generally reduced shoot iron content.
- Intervention effect At low iron, vanadium generally reduced shoot phosphorus in soybean and peas.
- Intervention effect At low iron, vanadium increased shoot phosphorus in flax.
- Association Soybean and flax yield data suggested manganese interacted with molybdenum and vanadium when iron was low.
- Association Yield data showed no interaction between molybdenum and vanadium.
- Observation The three metals had additive effects with respect to iron.
