Of all the factors that contribute to production costs and yield, nitrogen has one of the largest impacts. Small improvements to nitrogen (N) utilization can boost profitability. 360 Yield Center offers new tools that allow you to measure and supply the right amount of N when the plant is ready to use it.

Why Our Approach Is Different

The golden days of one-and-done N application are over. With today’s tight margins, you want to be sure you’re making the most of your N application. Up until now, you may have put down 200 lbs. of N early and let it run its course. But, as little as one big rain could leach it away. And, that could be the difference between a good year and a great year. Why risk it?

360 Yield Center is giving you control with new tools to help you precisely manage N availability by testing mid-season and applying more N where and when it’s needed. It’s called the base-plus approach. We’ve conducted side-by-side trials across the Corn Belt that demonstrate how taking a base-plus nitrogen management approach improves yields and profits when compared to a one-and-done approach.

We Call it the base-plus approach
And this is how it works
BUILD
MEASURE
APPLY

Build A Nitrogen Base

Apply a base rate of N in the fall or spring — whether through anhydrous or weed and feed at planting — to ensure your corn gets off to a great start, but save some of your N supply for later in the season. Your corn uses almost 75% of its overall N needs after V10 — so if you run out of N after pollination, growth will shut down, ears will be shorter and grain fill will suffer. Instead of putting all your N out early when it’s vulnerable to loss, save some and let Mother Nature show her hand. Then, test your soil to find out how much N you’ve used, lost or gained through mineralization, and refuel the crop to get to the finish line.

Measure how much nitrogen is left

Understanding in-season N availability can be a real guessing game. Before you make mid-season N application decisions, it is important to know exactly how much nitrate N is present through real-time measurement. Use 360 SOILSCAN to test N availability — and soil pH — in the field with the accuracy of a soil lab. Knowing how much N is left and how much you need are two different things. 360 SOILSCAN has a Corn Nitrogen Need Calculator to build an N recommendation based on yield goal, corn growth stage and soil organic matter. So, now you can build N application plans instantly after measuring your soil.

Apply at the tight time and place

Mid-season N application is key to feeding your crop later in the season when your corn needs N most to reach its yield potential. The sidedress window is now so wide you can split-apply N with more confidence. 360 Y‑DROP provides flexibility and control for timing midseason N application anywhere from V6 to tassel — a window of more than 30 days. And, where N is applied is just as important as when it is applied. A corn plant acquires more than 60% of its N from a horizontal radius of about 7 inches from the stalk base. 360 Y‑DROP places liquid N at the base of the stalk, where even modest dew pushes N to the root zone for rapid uptake.

+29.5 bu/A: Southern Illinois

This trial compared eight different application plans with 16 total passes in the field and compared the yield impact of mid-season nitrogen application with a one-and-done approach.

Split nitrogen application in this trial improved yield as compared to the control (200 lb. of N applied preplant). The trial also showed that the addition of 360 Y‑DROP N application increased yield by an average of 29.5 bu/A. In low ground areas where heavy rain had a large impact through ponding, 360 Y‑DROP boosted yield by 35 bu/A.

+32 bu/A: Central Illinois

This trial compared several different nitrogen application plans, including a prescription determined through in-season nitrate nitrogen measurement with 360 SOILSCAN.

By using in-field soil testing equipment, the farmer knew exactly how much N was needed to finish the season and the yield results paid off. In the strip where 150 lb. of nitrogen was applied at V9 per the 360 SOILSCAN recommendation, the yield was 212 bu/A — the largest yield of the entire trial.

By trying a split-nitrogen application – where 125 pounds was applied pre-plant and 100 pounds was applied at V9 with 360 Y-DROP — this grower experienced an advantage of 32 bu/A when compared with a one-and-done application of 225 pounds of AMS preplant.

+47 bu/A: Central Illinois

This side-by-side central Illinois trial compared N timing and placement with 360 Y‑DROP versus a coulter. The coulter application was done at V6 (early June) and the 360 Y‑DROP application at V16 (early July). Both sidedress applications were 150 lb. of N after 100 lb. of N was applied as a base on the whole field, including 30 lb. with the planter (2x2) and 70 lb. of weed and feed worked in with a vertical tillage tool just prior to planting. This yield map shows actual harvest data and yield results.

+56.3 bu/A: Southern Michigan

This side-by-side trial in Southern Michigan aimed to compare yield impacts of traditional sidedress applications at V6 with a coulter bar with a mid-season N application at V10 with 360 Y‑DROP. The same amount of nitrogen was used for both applications — timing and placement were the only variables.

Historical rainfall totals early in the growing season put much of the N applied at V6 at risk of loss in the environment. In contrast, the V10 application of N with 360 Y‑DROP repositioned N when the corn's needs were larger.
