Effect of sulphur upon plant response to phosphate

Abstract

Native sulphur is supplemented by variable additions from rainwater, irrigation water, fertilizers and insecticides. Sulphur d e ficiency, however, still exists in many parts of the w oild and could be overcome for high yields by mixing together elemental and rock phosphate, applying sulphur containing fertilizers, growing clover and grass in sulphur-deficient soils, by presence of soluble salts in fertilizers, applying ammonium sulphate under limed condition and ammonium sulphate with triple superphosphate.
