Other claims from this paper (9)
- Observation Chlorosis occurred except in the two higher ammonium treatments.
- Intervention effect Increasing Fe supply raised shoot dry matter yield only slightly.
- Intervention effect Ammonium produced higher shoot dry matter yields than nitrate at each Fe level.
- Intervention effect Rhizosphere sand pH fell about 0.5 unit with ammonium.
- Intervention effect Rhizosphere sand pH increased about 0.2 unit with nitrate.
- Intervention effect Ammonium approximately doubled shoot Fe, Zn, Cu and Mn concentrations and uptakes versus nitrate.
- Observation Nitrate fed plants had shoot Fe concentrations around 40 μ g g− 1 dry wt., below the critical deficiency range.
- Observation Mn concentrations of nitrate fed dressed plants were in the deficiency range.
- Recommendation Fe dressing with ammonium fertilization and nitrification inhibition is proposed to avoid early chlorosis.
