Update on Soil Profile Nitrate Concentrations
Carrie Laboski, Extension Soil Fertility/Nutrient Management Specialist
The soil nitrate monitoring network website was just updated with soil profile nitrate concentrations for 26 sites throughout Wisconsin. The results are not unlike two weeks ago. Some sites had large losses of nitrate over the winter while others had moderate or typical losses. Nitrate in the soil profile remains high in some locations. Follow guidelines in articles on May 2 and April 25. You can see all of the data at: http://uwlab.soils.wisc.edu/soilnitratemonitoring/. The website will be updated again next week.
