RE: Grass and weeds in my clover
Soil tests give very accurate readings on Phosphate and Potash levels and needs. But, and this is seldom explained, it gives a lousy indication on Nitrogen needs. Nitrogen is contained in the organic matter and is released as the OM breaks down. What you should do for N levels is understand Nitrogen removal rates based on the crop planted. A very good sarting point for most food plots would be to assume that you need about 70 pounds of actual N per acre if its a mixed stand of grasses and legumes. Any more is probably wasteful, less down to about 40 pounds would be ok, less than 40 is probably not enough.
