Abstract
Iron chlorosis is widespread in corn, sorghum and soybeans growing in calcareous soils in Iran. A field experiment was conducted to investigate the effect of Fe, Mn and Zn by corn,sorghum and soybeans. Elemental S (powder sulfur) was incorpoated into the soil before planting with the rates of zero, 100, 200 and 400 Kg/ha. Results showed that elemental S decreased the soil pH and HCo**3 concentration of Iron, and Zn uptake increased while Mn uptake decreased treatments and Iron chlorosis was corrected. Yield increase over control was significant for sorghum and soybeans for all and every teatment. For corn, however yield showed signigicant increase over control only for 200 and 400 Kg elemental S/ha. The results indicated that elemental S treatment was an effective means to alleviate iron chlorosis as well as to increase yield for corn,sorghum and soybeans in calcareous soild.
