Fertile Soils					Decrease application with increasing formulas on fertile soils																					applications
		Increase application with decreasing formulas on lighter and poor soils																Light Soils
For the best soils and lighter feeders in moderate and Northern moist climates reduce application and formula.
For poorest soils, heavy feeders and in Southern dry, hot climates increase application 1 step.
Using cover and green manure crops and mulching brings you 1 step lower in formula or application.
For fruit trees figure out how many trees to the acre, divide the NPK requirements per acre by the number of trees, and you will find how much to give per tree,
according to the requirement of the tree.
