N2 - Preliminary experiments indicate that potassium fertilization at a rate of 270 mg K/kg soil ameliorates iron deficiencies in peanuts grown in an extremely calcareous soil (63% CaCO3). Amelioration was greater with the application of KC1 than with that of KNO3 or K2HPO4, indicating that the cation:anion balance of roct uptake is involved. Potassium chloride application caused a 73% increase in the chlorophyll content; this value is 90% of that of the FeEDDHA treatment. Manipulation of the cation: anion balance of macronutrients may prove to be an effective means of controlling lime-induced chlorosis.
