Productivity maps

Productivity maps are derived from crop production history and remote sensing, and is used to determine variability and make site specific management decisions. 

Variability is analyzed through evaluation of Normalized Differential Vegetation Index in past crop seasons, given it's high correlation with yields in key dates. The result is a Productivity Map, which divides the field in classes, from very low to very high productivity polygons. In this section //put link, analyzes in more detail how Productivity Maps are generated.

Why is it important to recognize variability

//put picture of field w/variability Two areas in a field are different environmental zones if the same crop, with the same treatment, presents marked differences in its yields.

How it works

How it's used → recognize – caracterize – take management decisions → go to how are MP used? ↔ relate with zones & templates.
