* - Use Soil Group from soil test report, if available.
** - Y = pounds fertilizer P2O5 or K2O per acre required; X = soil test P or K

 

Comments

For reseeding clover, or clover seed harvest, apply 1 to 1.5 pounds B per acre.

Where legume covers less than one-third of the ground, apply 60 pounds of N each time forage is grazed down or cut for hay.
