1. Can Kura Clover and Winter Rye Covers Mitigate Nitrate Leaching In Irrigated Sands?Cover crops are gaining more popularity as a mitigation tool to prevent nitrate (NO3--N) leaching from the corn (Zea mays L.) and soybean [Glycine max (L.) merr.] fields of Minnesota. Leaching of NO3--N is not only a monetary loss for growers, but also results in groundwater contamination. Winter rye (Secale cereale), a commonly grown cover crop in Minnesota and kura clover (Trifolium ambiguum), a less... |
2. A Minnesota-Wide Assessment of Critical Pre-Plant and in-Season Soil Nitrate for Adjusting Nitrogen Rate GuidelinesThe pre-plant (PPNT) and pre-sidedress (PSNT) soil nitrate tests are often used as indicators of soil nitrogen (N) availability in Minnesota. The assessment of available soil nitrogen (N) provides corn (Zea mays L.) growers with key information on N credits to adjust their N fertilizer rates. However, current N management recommendations in Minnesota were based on research conducted 40-yr ago and did not specify differences between environments and management. Through a comprehensive...
