Y = 100 - 3.28X
2
Y = 100 - 0.56X
4
Y = 100 - 1.40X

Y = 100 - 0.42X

4
Y = 110 - 0.41X
* - 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.
