The efficient use of resources is critical in all aspects of field-crop production. Multiple studies at Northwest ARS focus on effective management of crop fertility inputs. Current projects examine both the input level needed to achieve maximum yield, and the level that allows for maximum economic return. Other research studies are designed to compare various nutrient sources, both organic and inorganic, along with a variety of application timings. The station's location within the Maumee River Watershed allows it to contribute to the water quality work of CFAES to reduce nutrient pollution in the western Lake Erie Basin. 

Because of their high clay content, northwest Ohio's soils do not lend themselves to no-till production, a practice widely used elsewhere in the state. Instead, scientists concentrate here on reduced tillage, which has long been utilized in American agriculture and contributes to production efficiency and soil quality. Northwest ARS has been a pioneer in the study of varying levels of tillage, with long-term plots examining tillage and rotation variables since 1964. These plots have served as a resource for countless scientists in Ohio and around the world studying soil carbon sequestration. 

Studies related to both insect and disease management are an important part of Northwest ARS's research program. Flat, high-clay soils drain slowly, providing and optimum breeding ground for soil-borne diseases. As a result, management of these diseases is vital to profitable crop production in northwest Ohio. Researchers continue to examine treatment and management alternatives through resistant varieties, seed treatments, and fungicide applications; they also work to identify new disease strains that develop over time. Research involving insect management continues to evolve to include seed treatments, crops with genetically modified traits, and other control measures.
