Soybean response to starter fertilizer containing sulfur
Application timing and placement are other factors that affect nutrient uptake. However since both treatments were within the established S sufficiency range, the effects of any further increases in S uptake on soybean yield is a matter of conjecture at present. Additional information on nutrient sufficiency ranges is found in the Michigan State University Extension Bulletin E-486, “Secondary and micronutrients for vegetables and field crops.”
