Influence of lime on nitrogen fixation by tropical and temperate legumes

Abstract

A nitrogen deficient Oxisol which had been fertilized with P, K, Zn and Mo received CaCO3 at rates which increased continuously from zero to 22 tons/ha. Liming produced a range of pH in the saturation paste from 4.7 to 7.1; a range of calcium in the saturation extract from 0.3 to 3 meq/l; and a significant decline in available manganese. Responses of 9… (More)
