Objectives of these studies were: 1. To determine the effect of various S fertilizers and rates of S application on the yield of both alfalfa and corn grown on sandy soils. 2. To determine the residual effects of a single application of S fertilizer on the production of alfalfa. 3. To measure the influence of S fertilizers and the rate of S applied on the S content of corn and alfalfa tissue and S uptake by these two crops. 4. To develop a soil testing procedure which accurately predicts the requirement for the application of S fertilizers to alfalfa and corn on sandy soils
