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.”
This study was funded by the Michigan Soybean Promotion Committee. The author wishes to thank Will Willson, soybean producer from Perry, Mich.; Brian Martindale, Agro-Culture Liquid Fertilizer dealer in St. Johns, Mich; and Mike Staton, senior MSU Extension educator, for their support and collaboration in this study.
