Synopsis

Synopsis

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.
