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.

Key Takeaways

  • 360 SOILSCAN allowed the grower to measure in season and adjust nitrogen rates.
  • 360 Y-DROP allowed the grower to make an additional application later in the growing season when the crop needed it most.
  • An additional application with 360 Y-DROP resulted in an average of an additional 15bu/A.

The grower ran a comparison of pre-plant followed by sidedress applications versus pre-plant, sidedress and an additional 360 Y-DROP application with less N applied overall.

+ BASE PLUS APPROACH VS. PRE-PLANT PROGRAM

Key Takeaways

  • Less nitrogen was applied overall when following the Base Plus Program, thus resulting in input savings.
  • The Base Plus Program resulted in an average of 11 bu/A more than the Pre-plant Program.
  • The Base Plus Program allows the grower to wait and adjust the amount of nitrogen applied until later in the season.

The grower, Brenton Peters, ran a comparison of an all pre-plant nitrogen program versus a base plus program with 360 Y-DROP.

+ 360 Y-DROP VS. COULTER

Key Takeaways

  • 360 SOILSCAN allowed the grower to measure in season and adjust nitrogen rates.
  • The Base Plus approach allowed the grower to make an additional application later in the growing season when the crop needed it most.
  • Placement of nitrogen with 360 Y-DROP resulted in an average of 5 bu/A more than coulter.

In this trial the grower compared other management strategies to 360’s Base Plus approach.

Coulter applications were made at V8 as that was the latest time the grower could get into the field with the coulter bar. With a dry June and high mineralization rates, nitrogen wasn’t needed at that time. An application with 360 Y-DROP was also made at V8 to compare placement of N as well.

360 SOILSCAN was used to pull nitrates until results got below 10 ppm at V12 at which point the grower decided to apply additional N with 360 Y-DROP.
