              Potassium application rate (lb K2O/acre)  
    *For grass pastures, split the total nitrogen rate into two or three separate applications. Apply one third to one half of the nitrogen in early spring, one third to one half in June, and the remainder in late August. For alfalfa-grass pasture systems, apply two thirds of the nitrogen in early spring and one third after the hay crop is removed.                 
          Sulfate application rate (lb SO4-S/acre)  
                   
          Boron application rate (lb B/acre) -  
                   
    *Applying Nitrogen at rates of 160 lb/acre or higher at one time to a pasture can cause nitrate toxicity issues in cattle.
