Adjustment of Iron Supply to Requirements of Soy Bean in Solution Culture

R. P. Marsh; J. W. Shive Botanical Gazette 1925. doi:10.1086/333436

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 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.
Recommendation The authors considered fixed-interval iron applications impracticable because plant environment changes iron requirements.
