ONE type of investigation of crop responses to commercial fertilizers employes an initial application of the relatively large amounts of fertilizer required to bring the plow layer to specified fertility levels as determined by chemical tests. Such an experiment has been under way on Almena silt loam of central Wisconsin for a period of 4 years (io). The purpose of the present paper is to summarize the influence of the various soil fertility levels established in this experiment on the botanical composition and the associated mineral content and balance in the vegetative tissue of the legumes which survived.
