360 Y-DROP®

Overview

Corn uses 75% of its nitrogen after V10. Make sure it has enough nitrogen to finish the season strong with 360 Y-DROP. 360 Y-DROP allows you to apply nitrogen exactly where it’s needed — as late as VT, giving you the widest sidedress window ever, for more flexibility and bigger yields.

KEY FEATURES

  • Late-season nitrogen application
  • Precision nitrogen placement
  • Variable rate nitrogen application

NITROGEN WHERE YOU NEED IT

A corn plant acquires more than 60% of its nitrogen from a horizontal radius of about 7 inches from the stalk base. Traditional sidedress methods apply nitrogen in the middle of the crop row — nearly 15 inches away. With 360 Y-DROP, you can apply nitrogen within 2 to 3 inches of the stalk base — that means nearly 80% of the root mass is in the application zone. The funneling effect of corn leaves then pushes the nitrogen to the root mass for rapid uptake, even with modest precipitation or dew.

MORE FLEXIBILITY, MORE CONTROL

Never before has the sidedress window been so wide. Y-DROP gives you the flexibility to extend the midseason application window from V6 to VT — more than 30 days — for more control over when and how your nitrogen is applied.

  • New narrow-row design with four-position adjustable arms allows precision placement in 15-inch to 36-inch rows
  • Variable rate nozzles are available for customizing the rate, time and placement of nitrogen
  • New breakaway mounting brackets allow for easier navigation across hills and uneven terrain
  • Newly designed shield keeps leaves from wrapping around the riser or hoses

FAST MOUNTING FOR EFFECTIVE APPLICATION

360 Y-DROP is available in 20-inch to 30-inch row spacing. You can install and remove it easily on most sprayers, including:

  • Self-propelled sprayers
  • Pull-behind sprayers
  • High-clearance sprayers

+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.
