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).
