We're utilizing satellite technology or remote-sensing technology to do bio-vegetation index maps. We take soil samples based on the zones that are in those bio-vegetation index maps. Satellites give us the maps. We go into the field and soil-test, and then agronomists like me will make recommendations based on the amount of fertilizer that we want to hit, based on the yield target. We put these into air seeders, and as the air seeders go across the field with GPS guidance, they regulate the amount of fertilizer to hit the target yield.
