After Nitrogen, Phosphorus is the second most frequently limiting macronutrient for plant growth.
Phosphorus plays a major role in the growth of new tissue and division of cells. It stimulates early root, plant growth, flower setting and hastens maturity. Plants perform complex energy transmissions, a function that requires phosphorus. It is linked to a plant’s ability to use and store energy, including the process of photosynthesis.
The amount of phosphorus fertilization depends on the amount of plant available phosphorus in the soil, the pH of the soil and the requirement of the crop.
