Other claims from this paper (10)
- Intervention effect Daily adjustment of iron supply produced vigorous soy bean plants across solutions and compounds.
- Intervention effect Slightly excessive available iron could cause chlorosis.
- Intervention effect Slightly excessive available iron could cause iron toxicity.
- Observation Healthy green plants had lower dry-weight iron percentages than chlorotic plants.
- Observation Healthy green plants had lower dry-weight iron percentages than plants with iron toxicity.
- Observation Iron was uniformly distributed in healthy plant stems and leaves.
- Observation Chlorotic plants had high stem iron and very low leaf iron.
- Observation Plants with iron toxicity had high iron throughout.
- Intervention effect Small additions of iron tended to equalize iron distribution and maintain green plants.
- Recommendation The authors recommended keeping soluble iron as low as possible without inducing chlorosis.
