2-YEAR MULTI-LOCATION STARTER FERTILIZER RETURN ON INVESTMENT

In the past, I haven’t recommended using starter fertilizer on soybeans because we typically don’t start planting until later in the year. By then, soils have warmed up and we start seeing active mineralization of organic matter and a more consistent release of nutrients. However, because of the higher yield potential with early planted soybeans, I think the addition of starter fertilizer could have a place in our soybean management. This year, we saw a yield increase in all but one of the treatments over four locations.
