Tillsonburg Ont
From my 2 years with a Greenseeker I like going into field and setting highs and lows from crop on first time across field.Then cap highs and lows so rates don't get out of control.
Example NDVI of .8 and above might all get 8 ga/ac (min pump setting) while .7-14ga, .6-20 ga .5-25 ga, .4 and lower would max at 25 ga/ac.As you go through field I will tweak the settings a bit.This way if a farmer wants 20ga/ac overall I can put it where best suited as long nothing crazy is going on in his soil.This way if the grower can have a $ amount in mind for cost.
