Don’t Short Micronutrients in Your Plant Nutrition Plan

Sprayer
Micronutrients are a critical part of an effective fertility plan. Even though they’re used in a more nuanced way than macronutrients, they still play a significant role in plant growth and development, which can help you achieve greater ROI and yield potential in your corn and soybeans. As you finalize your inputs for next season, consider how micronutrients should factor into your overall nutrient strategy.

Don’t have the perfect soil? You still need a plan

On acres with suboptimal yield potential, you may be more conservative with your inputs but it’s still important to invest in micronutrients. With marginal-producing acres, I recommend doing a baseline nutrient application for crop removal using production history or any past in-season indicators such as imagery from the R7® Tool. Success with these types of acres isn’t about putting a flat layer of nutrients over them and calling it good. It’s about dialing in to the performance of each acre to help optimize ROI potential. Discover zones within each field to set the stage using macronutrients as primary components. Then, dial in opportunities through crop scouting and tissue sampling to use micronutrients for optimizing overall yield potential.

Get nutrient application timing right

All 17 macronutrients and micronutrients are essential to crop growth and production. But remember that the right nutrient needs to be used on the right crop at the right time. Work with your agronomist to prepare a comprehensive nutrient plan that allows you to target nutrient applications when the plant can use it the most.

Get the right micronutrients to the target

According to WinField® United tissue sampling reports, the micronutrients that proved to be most beneficial to farmers this season in terms of yield response were zinc in V8 corn, boron and manganese in VT corn and sulfur and manganese in R2 and R3 soybeans. Nutrient deficiencies can limit a crop’s ability to develop to its full potential but holes in your crop’s nutrition may be mitigated by proactively developing a plan for next season.
 
After reviewing in-season tissue sampling and end-of-year soil sampling results with your trusted advisor, find the right micronutrient products to correct any deficiencies on your priority acres. WinField United offers three key micronutrient product lines to address your plant nutrition needs.
  • Lignosulfonates: These are dry products that can be applied in a broadcast, strip till or sidedress manner. Lignosulfonates are naturally occurring compounds derived from plant material. Micronutrients are complexed with lignosulfonates to create a granular product for soil application that helps improve mobilization and nutrient uptake for the plants.
  • MAX-IN® micronutrients: These foliar-applied products are used for in-season nutrient management and can be tank mixed with herbicides, insecticides and fungicides. MAX-IN Ultra ZMB® with zinc, manganese and boron, MAX-IN Zinc and MAX-IN for Beans are just a few of the products in the portfolio. MAX-IN products contain patented CornSorb® technology to greatly increase the movement of micronutrients through the leaf cuticle and into internal structures.
  • Liquid chelated products: These are typically used for in-furrow or liquid sidedress applications to help increase nutrient efficiency and availability to crops. WinField United offers Citri-Che® micronutrients, which are chelated with citric acid and EDTA, and Ultra-Che® micronutrients, which are fully chelated with EDTA or HEDTA. The chelators in Ultra-Che micronutrients help provide strong, reliable protection against micronutrient soil tie-up.
Products in the WinField United micronutrient portfolio have been tested through the Answer Plot® program as well as on-farm, which together provide WinField United with the best opportunity to position the proper product on your acres. Testing at the WinField United Innovation Center also offers assurance of product integrity and favorable tank mixability, as well as greenhouse analysis of performance.

What to do in the spring

If you took tissue samples this season, review test results with your agronomist to determine what nutrient needs you may have to tackle in 2022 and when. If you don’t have tissue samples from your farm, talk with your local retailer about accessing a tissue sample data set from your area to find out what micronutrient deficiencies might be evident in your geography.
