Growers can use TerrAvion imagery to create management zones that correspond to actual plant growth. In this example, the June 15th imagery shows a correlation between plant vigor and soil type, with early-season plant growth being most vigorous in the horseshoe-shaped area of loamy sand (Fb soil-type). The September 20th imagery shows that this pattern is even more pronounced three months later, where the plants in the loamy sand remain vigorous while the remainder of the field starts to decline. Such relative performance of the field across the growing season is very powerful in helping to design effective management zones.
Use vigor maps to create management zones and evaluate real-time performance of your fields and to inform all management actions. While yield maps are a trusted form of data for the end of season crop performance evaluation, they are of limited value as an in-season management tool.
