Controlled Release Nitrogen: Another Tool in the Toolbox

With harvest wrapping up this fall our attentions are being drawn to the next growing season already. Now’s the time to choose what seed hybrid to plant, which tillage method to implement, how much fertilizer to apply, and in some cases what source of that fertilizer to use. Controlled release fertilizers (CRF) have been on the market for some time now and have shown good results in certain situations. Before you jump in, consider how a CRFs work and whether it would be a good fit for your operation.
What are the main forms? CRFs fall under a broader group of fertilizers called enhanced efficiency fertilizers (EEFs). This group includes: Controlled release fertilizers. Physical barrier such as a resin or polymer. Release affected mainly by temperature, but also by thickness of the coating, moisture, handling, and placement. Rate of release is fairly consistent. Slow release fertilizers. Microbial or chemical barrier effected by temperature, moisture, soil pH, and microbial activity. R…

Take a proactive approach to managing Palmer amaranth in Minnesota crop production fields

Jeff Gunsolus, Extension weed scientist
Early detection and eradication of Palmer amaranth will pay you dividends in reduced management costs. Differentiating Palmer amaranth from the other common amaranth species is challenging. However, because Palmer amaranth and tall waterhemp are biologically similar, you can approach this challenge with the weed management tactics that you would use for effective tall waterhemp control.

A Look Back at Soybean and Corn Diseases in Minnesota in 2018

Dean Malvick, Extension plant pathologist
This article is a recap of some of the most common and problematic diseases of soybean and corn in Minnesota in 2018. Looking back at diseases that affected crop growth and yield can help explain why yields were not as expected in some areas and help prepare for next year. This reflects a broad overview, although much variation occurred across Minnesota fields based on weather, variety, cropping practices, soil type, and geography.
