Vertical Distribution of Topdressed Fertilizer Phosphorus and Potassium in Relation to Yield and Composition of Pasture Herbage1

Yield of grass-legume pasture for 2 years was increased by fertilization with P but not with K. Large amounts of nonexchangeable K were released when crop removal of K exceeded rate of application, but only relatively small amounts of applied K were fixed even when rate of application exceeded crop removal. No movement of P was detected below 3 inches, and no movement of K below 6 inches.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
