BEFORE intelligent recommendations can be made regarding applications of fertilizer for certain crops, an understanding is needed of the relation that normally exists between the yields of these crops and the levels of available phosphorus and potassium in the soils on which they were grown. It was for the purpose of obtaining more information on this relation that experiments were started in 1942-43 on Spencer and Antigo silt loams in northwestern Wisconsin. Because of frequent failure and low yields of alfalfa and clover in this area, special attention was given to the relation that these levels bear to yield and survival of these legumes.
