Abstract

Peanut (Arachis hypogea cv. Shulamit) grown on very high calcium carbonate (CaCO₃) content soils is showing iron (Fe) chlorosis symptoms. Supplying the plant with ammonium sulphate ((NH4)2SO4) in the presence of nitrapyrin (N-Serv) for preventing nitrification reduced Fe chlorosis. Nitrate (NO3) developed in the soil with time, even with nitrapyrin present. When ammonium (NH₄) was even less than 20% of the total mineral N in the soil, no Fe-stress could be observed, suggesting that the NH₄ uptake by the plant and the consequence of hydrogen (H⁺) efflux occurs from the root to the rhizosphere, resulting in a decrease of redox potential near the root, and solubilizing enough Fe near the root to overcome the chlorosis.
