# Multi-Year Zones

Historical (multi-year) management zones provide insights about every spot in the field.

Historical (multi-year) management zones are built based on 30+ years of the archive of satellite imagery. Images with peak vegetation during every season are automatically selected as inputs for analytics. Otherwise, every such image represents a potential yield file for the related year.

The field crop development pattern helps to know the agricultural area better and to apply the right decision with the right input rates in the right spots. Historical management zones could be used as a blueprint for prescription (Rx) files for seeding, fertilization, zones based soil sampling.
