Productivity maps overview
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.

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