The Landus Cooperative Complete Zone Map is a top-tier zone management system which includes up to 12 management zones. These 12 management zones are developed from three layers of data, which include:
- Electrical Conductivity Data gathered by a Veris 3150 EC Cart
- RTK Elevation
- Yield Potential Layer developed from historical satellite imagery or raw yield data.
This top-tier zone management option allows your Landus Cooperative Field Sales Agronomist to uncover both excess and deficient nutrient carryover levels that often have a direct carryover to historical yield. Through the Complete Zone Map, you will be better able to place your inputs, such as fertilizer and seed, in the right zone, therefore, maximizing your return on investment on each acre of your farm.
Once the field is properly zoned, we can better manage the inputs on each specific zone, to maximize its production and profitability, while minimizing the cost.
As you can see, each layer is represented well on the zone map. You can see that the really heavy and light soils (dark blue and red on EC map) across the field tended to have less yield potential, while the moderate soils (green on EC map) have the highest yield potential. Also, you can see the highest point on the field in the top center of the map, that the crop tends to burn up. When you look at these layers closely you can see exactly how the zones were derived.
Once the zones were created, we went out into the field to verify our information. The results were the right one. As you look at the drone photo you can see the zones perfectly outlined by the crop.
From walking the field, it was easy to tell what zone we were in by looking at stalk quality, as well as ear size.
