How to Correct the Nitrogen Loss
Nitrogen loss will be a big concern in 2019 given all the wet weather. As such and for good reason, there have been many questions regarding how much N may have been lost and what we can do to go about correcting these N loss problems. To address these concerns and questions I have made a video discussing these various issues. As you will learn in this video I will produce a second video with PSNT soil test results and nitrogen model estimations of N loss which may refine my initial thoughts and recommendations. 2019 is off to a rough start, but the more in-the-know you are, the better your yield.
- If you had more than 10 inches of rain since N was applied its advised that you recommend applying more. Nitrate soil tests are confirming this.
- N models don’t seem to be aligning very well with the nitrate nitrogen tests that I took and some general knowledge about what we know regarding rain fall amounts and precipitation.
Bottom line, N models may be valuable, but they don’t replace good sound experience and agronomic advise. Follow recommendations from N models with caution.
