Title

Other claims from this paper (8)
- Intervention effect Without added iron, zero nitrogen produced no chlorosis symptoms.
- Intervention effect Without added iron, chlorosis symptoms became more pronounced as nitrogen increased.
- Intervention effect High nitrogen induced true iron deficiency in soybean leaves.
- Intervention effect High nitrogen increased leaf phosphorus, copper, and aluminium alongside iron deficiency.
- Intervention effect With iron applied, vegetative yield was highest at 100 μg N/g soil.
- Observation Zero, 200, and 400 μg N/g soil gave closely similar soybean yields when iron was applied.
- Intervention effect Nitrogen increased soybean iron uptake when iron was supplied as a chelate.
- Intervention effect Leaf mineral analyses differed between soybean plants supplied and not supplied with iron.
