Abstract An experiment including a factorial combination of 4 rates of S and 3 rates of Mo fertilization was conducted on a low‐S, low‐Mo soil to evaluate the effects of soil S level on the absorption and utilization of Mo by peas. The uptake of soil and fertilizer Mo was markedly reduced by applications of sulfate fertilizer. The higher rates of S fertilization also reduced the apparent efficiency of utilization of Mo by the plant. Higher plant Mo levels were required for maximum yield and N fixation as the SO 4 ‐S content of the plant tissue was increased by S fertilization. Correlation coefficients of 0.78 and 0.94 were obtained with response surface equations for seed yield and vine N content as functions of the Mo and SO 4 ‐S contents of the plant tissues. Maximum pea yields were associated with plant tissue Mo contents of 0.3 to 1.0 ppm. and 200 to 600 ppm. of SO 4 ‐S.
