Phosphorus and micronutrients (zinc, copper, iron and manganese) are the essential nutrients which are required for normal plant growth. Phosphorus and all micronutrient cations are mutually antagonistic in certain circumstances which can cause yield reductions in many crops due to their deficiencies. Deficiencies typically happen when a nutrient is available in small amounts. In this phenomenon, the nutrient is present in marginal to normal levels but the antagonizing nutrient is available in such a large amount that it induces the deficiency of the other. The effect of phosphorus application on the availability of micronutrients showed that the application of phosphorus decreases the concentrations of Fe, Zn, Cu and Mn in the soils which indicate negative interactions between P and micronutrient cations while the concentration of Mn increases in some cases indicating synergistic as well antagonistic effect of P application on Mn availability in soils to plants.
