Phosphorus is one of the essential nutrients needed for plant growth and development.  It is considered a macro nutrient, meaning that it is required in large amounts.  In the attached article, Dr. Larry Oldham, Extension Professor Soil Health, Soil Fertility, Nutrient Management, and Soil Conservation and Management discusses different forms of P in the soil, how it is taken up by plants, proper nutrient management, and fertilization of crops, as well as some environmental concerns associated with P use.  This article will give the reader a better understanding of the role of P in crop production, and how to manage its use.
