The Soil Fertility/Nutrient Management program at MSU focuses on the processes that affect nutrient cycling so that they can be managed more sustainably. Soil testing can detect low nutrient levels that lead to possible crop nutrient deficiencies. In addition, soil testing allows for timely adjustments in fertilizer applications, reducing input costs. Understanding the economics of fertilizing, yield goals, and crop quality, along with soil fertility management can assist the producer in meeting profit goals. Currently, the effects of cropping systems and tillage systems on nitrogen and phosphorus availability are being investigated. Research conducted at MSU, the Agricultural Research Centers, and throughout the region, are synthesized into fact sheets, modules, and presentations geared toward extension agents, crop advisers, farmers, ranchers, and/or homeowners.
