Heard about the Haney test and want to learn more about how it might be used in Wisconsin? Listen in while we chat with leading UW researchers and outreach specialists Chris Bandura, John Jones, and Andrew Stammer on this topic. We dive in deep discussing how the Haney test can be used practically on-farm, how it calculates fertility recommendations differently than other soil tests, and what that means for Wisconsin cropping systems.

Interest in biological products that aim to provide nitrogen to nonlegume crops by fixing atmospheric nitrogen for non-legume grain crops has increased in recent years. University of Wisconsin–Madison conducted field trials to examine if a popular gene-edited asymbiotic nitrogen fixer bacterial product, PROVEN 40, affected corn grain yield or corn grain yield response to nitrogen fertilizer.

A common misconception about livestock manure is that it is simply a waste product of the farm. However, manure is rich in many nutrients and is a valuable resource when applied back onto fields that can benefit from manure application. Research has demonstrated positive impacts to soil quality/health, crop production, and overall farm management when manure is managed effectively.

Karst topography and Silurian bedrock are areas that are more susceptible to water contamination due to shallow soils and increased number direct conduits to groundwater, such as sinkholes. When farming in these areas, and especially spreading manure, it is important to follow all rules and regulations.
