For more accurate fertilizer recommendations, use the equations below for your soil group:

Fertilizer Recommendation Formula
P2O5		K2O
Soil Group*	Equation**	Soil Group*	Equation**
1 & 2	Y = 180 - 1.91X	1	Y = 190 - 1.08X
3	Y = 180 - 3.16X	2	Y = 190 - 0.98X
4	Y = 180 - 1.33X	3	Y = 190 - 0.53X
		4	Y = 200 - 0.52X

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

K requirement level	2		N rate	100
Lime code no.	2		PK code no.	18
Mg code no.	2
