Spraying Herbicide

This past week I spent all week spraying Grazon P+D on 300 acres of pasture.  Monday was servicing and calibrating our 1,000 gallon sprayer with 25 spray nozzles.  Tuesday & Wednesday I put out 3 loads (3,000 gallons of mixture).  Thursday I switched to our 200 gallon boom-less sprayer for tighter areas.  Had rain Thursday night so I waited until Saturday to finish applying 3 loads (600 gallons of mixture).
