Title

Other claims from this paper (6)
- Mechanism Iron humate provided available iron through a chelate shuttle mechanism with slight synergy.
- Observation The contribution of chelates to iron nutrition decreased substantially after a few days.
- Observation The most efficient mixture had two parts iron humate and one part iron chelate.
- Observation HBED/Fe 3+ was the most suitable iron chelate because its lasting effect matched the long term humate effect.
- Intervention effect The mixture increased soluble soil iron.
- Intervention effect The mixture improved shoot to root iron translocation.
