Importance of Phosphorus to Plants. Phosphorus is a component of the complex nucleic acid structure of plants, which regulates protein synthesis. Phosphorus is, therefore, important in cell division and development of new tissue. Phosphorus is also associated with complex energy transformations in the plant. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity.
The P in NPK on a fertilizer bag stands for phosphorus. It corresponds to the second number on the fertilizer's label. Phosphorus is essential for many aspects of healthy, attractive plants, including flower formation, root development and fruit production. trip to a garden center will leave you facing shelves of fertilizer, or plant food, choices. Although they have different uses, each plant food should have the nitrogen, phosphorus and potassium (NPK) content on its label as a series of three numbers, such as 10-10-10.
