Quantify the effect of a comprehensive fertility program including MicroEssentials® SZ® (12-40-0-10S-1Zn) + Aspire® (0-0-58-0.5B) compared to a conventional fertility program of MAP (11-52-0) + MOP (0-0-60) or MAP Only in a four-year cropping system.
Evaluate the yield response of fertilizing soybeans in a corn-soybean rotation using Aspire® with Boron (0-0-58-0.5B) and MOP (0-0-60).
Researchers strive to refine double-crop systems for top-profit production. Year- round land use allows soil protection during winter months, recapture of some previous crop-use nutrients, improved cash flow, added market opportunities, improved use of labor and equipment, and more.
Some growers are considering a shift from a corn and soybeans rotation to continuous corn. More nitrogen (N) will be needed since soybeans will no longer provide some residual N. Other nutrient needs will also change, especially phosphorus (P). Corn, unlike soybeans, is planted early in soils that are more likely to be cool, moist and with a heavier residue cover. These conditions can suppress the uptake of P by corn and increase the likelihood of crop response to fertilizer P. Research shows that P, with some N, applied in a band two inches to the side and below the seed, boosts seedling access to a readily available supply of P.
