3 Tips for Preparing a Nutrient Management Plan

Planning for the 2021 season begins this fall, and a good place to focus your efforts is revisiting your nutrient management program. While the season is still fresh in your mind, think about what you’ll need to do ensure that your crops have what they need to thrive next year. Fall soil sampling and nutrient applications are tasks that can be completed after harvest to get a jump-start on the spring. Here are some other tips to fine-tune your nutrient management plan.

 

1. Consider your crop plan

Market uncertainties and environmental conditions may have you second-guessing your plan for next season. As you develop a nutrient management strategy, you’ll need to revisit your crop plan. Will you change your rotations? If so, that could change your fertility program. Consider your seed choices as you make fertilizer decisions as well. Higher-yielding hybrids and varieties require more intense fertilization, and some hybrids are more responsive to nitrogen fertilization than others. Ask your agronomist for fertilization recommendations as you make your seed decisions.

 

2. Sample your soil and your plants

If it’s been several years since you’ve taken a soil test, it’s best to get an updated analysis done. Soil sampling is key to understanding what the baseline nutrient levels are in your soil. It can help build the foundation for an effective fertility plan. If you tissue sampled at critical growth stages this season, be sure to use those findings to inform your nutrient plan for 2021.

 

It’s a good idea to look at past soil and tissue sampling results to help identify trends you may see over time. For example, if one part of a field is deficient in nitrogen every year, there may be things you can do to limit nitrogen loss in those areas. It is also a good time to identify areas in your field where variable rate nutrient application could be an option. Laboratories such as SureTech® provide customized analysis that can make record-keeping easy.

 

3. Stabilize your nitrogen

Fall can be a great time to apply nitrogen if you live in the Upper Midwest or I-states because weather conditions are often more favorable for application. In Ohio, the majority of the state does not fall apply nitrogen due to excessive precipitation. It’s been reported that up to 28% of nitrogen that farmers apply will be lost due to volatility, leaching and denitrification. The average loss in the Upper Mississippi Basin is 39 lbs. per acre.1 Regardless of when or how you apply nitrogen, stabilizers make sense.

 

Not all nitrogen stabilizers work in the same way, so your retailer can recommend the best option based on your preferred application method and whether you apply nitrogen in the fall, spring or in-season. You can also monitor nitrogen levels in-season with the R7® Field Forecasting Tool. The tool can help pinpoint exactly how much nitrogen you should apply and when to improve your return on investment potential.

 

Adequate plant nutrition is a requirement to meet a crop’s yield potential. Now is the time to look ahead to avoid lost opportunities next season. Contact your local WinField United retailer to build a comprehensive nutrient strategy.
