Abstract

All cropping systems require fertilizer inputs in order to maintain crop yields. Farmers continue to search for ways to increase soybean yields, such as applying micronutrients and using foliar applications of fertilizer. Although micronutrients are just as essential to plant growth as macronutrients, past research has indicated most Iowa soils can supply the micronutrient needs of soybeans.
