Is there a place for using a starter fertilizer when planting soybeans? Farmers often think of using starter fertilizers when planting corn for various reasons. These can include: giving roots early access to plant nutrients, to stimulate early plant growth, to improve stand uniformity, to add micronutrients, and hopefully to increase yield.
Kurt Steinke, associate professor, Soil Fertility and Nutrient Management Specialist for Michigan State University Extension has looked at research conducted when using starter fertilizer applied as a 2×2 when planting soybeans in 30 inch rows.
“The first thing to consider when thinking about using a starter fertilizer on soybeans, it what are your soil test concentrations,” Steinke said. “What are the P and K levels? If the K levels are not deficient, then a farmer can probably go without K in the starter.”
