** - Y = pounds fertilizer P2O5 or K2O per acre required; X = soil test P or K

 

Comments

For burmuda hay, apply N, P, and K as recommended before growth begins and an additional 100 pounds N after each cutting up to September 1. Loss of stand is sometimes due to K deficiency. Where large yields of hay are removed, apply 50 pounds K2O per ton of hay removed the previous season.
