Concentrated swine production has increased the manure supply and requires more management options. Soybean is a high nitrogen (N) accumulator and a good complement to corn for management of manure N surpluses. Soybean has shown to accumulate more N with swine manure applications, and improved grain N removal rates. Project objectives include determining the differences in N uptake and grain N removal between the crops; evaluating the changes in soil N and soil fertility and the associated effects on nutrient uptake of the rotated crops and ultimately grain yield and grain N removal; and developing manure management options for hog producers while investigating nonconventional practices to increase soybean production goals and profitability.
