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.
The third Focus on Forage webinar in the 2024 series, Focus on Annual Forages, features discussions around annual forage crops for Wisconsin farms, the nutritive value of and strategies around feeding annual forages on dairy farms, the nitrogen demand of cereal forages, and nitrogen carryover and rate planning considerations for 2024.
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.
Both karst and Silurian are terms related to geological features and formations that have had a significant impact on Wisconsin’s surface and subsurface geology and hydrology. Both Karst and Silurian bedrock are connected to sedimentary processes.
There is a lot of solar being sited in Wisconsin with some projects reaching a pretty massive scale. The traditional narrative has been hello solar, goodbye agriculture, however a new crop of farmers, researchers, and solar companies are thinking differently: how can we continue to farm this land between, under, and around solar panels?
In the increasing discussions about how to address climate change there are conflicting claims about the need to address methane (CH4) emissions. Some people argue that methane emitted by cows is a primary cause of climate change.
