SynopsisGrass yields responded strongly to yearly applications of up to 400 pounds of K per acre and at a slower rate to even higher applications. With 800 pounds of K, exchangeable soil K content was maintained and two-thirds of the applied K was recovered in the forage. At the 1600-pound rate, recovery in the forage was reduced but exchangeable soil K content was increased. K content of the forage increased with rates and with yields.
