This article provides guidance related to the importance of using the same lab to assess changes in soil health over time, in addition to the importance of sampling at a consistent time of year and depth when collecting samples for soil health evaluation.
In this video, Sam Bibby shares insights from on-farm research exploring the use of camelina as a cover crop compared to rye in corn-soybean rotations.
In this video, Jerry Clark covers variety trials, nitrogen and fungicide management, and quality testing for malting barley to meet craft brewing standards.
In this video, Scott Reuss, regional crops educator, UW–Madison Extension, presents findings from multi-year research trials investigating optimal sulfur application rates for winter wheat in northeastern Wisconsin.
In this video, Dan H. Smith explores practical tips for calculating seed needs, managing storage conditions, and evaluating the economic value of straw and nutrient exports.
Bridgette Mason from the Wisconsin State Climatology Office provides a detailed update on weather conditions across the state as of July 10, 2025.
Cover crops and annual forages provide the perfect opportunity for the synergistic integration of crops and livestock, reducing feed and fertility costs while providing the positive impact of forage crops and livestock grazing on soil health.
Explore 2024 Nitrogen Optimization Pilot Program activities, projects, and program details.
High soil pH does not have to derail your yield goals. With smart fertility planning, informed seed choices, and targeted nutrient management, Wisconsin farmers can manage high pH zones effectively.
An overview of the following soil health indicators: Soil Organic Matter (SOM), Soil Organic Carbon (SOC), Potentially Mineralizable Carbon (MinC), Permanganate Oxidizable Carbon (POXC), Total Nitrogen (TN), Potentially Mineralizable Nitrogen (PMN), Autoclaved Citrate Extractable (ACE) Protein, and Aggregate Stability (AS).
In years of low commodity prices, most farmers think about where they might be able to cut costs. Some might begin to think about alternative crops can fit into row crop production. Enter the sunflower.
In this video, Hava Blair, researcher, UW–Madison Department of Soil and Environmental Sciences, presents an in-depth overview of the Wisconsin Phosphorus Index (P Index), a modeling tool used to estimate phosphorus runoff from agricultural fields to nearby surface waters.
