e0“Dressing sorghum seeds with Fe chelates in conjunction with NH4 fertilization supplemented with an inhibitor to prevent nitrification would appear to be a worthwhile approach to ensure an initial source of Fe to the young developing plant in the avoidance of iron-induced chlorosis”

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.
- Intervention effect Increasing Fe seed dressing had little effect on shoot Fe concentration or uptake with 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.
