Today we had Howard's fertilizer spread our per-emerge fertilizer . The analysis is 12-0-20 with barricade. The truck spreads about 85 acres and we spread the other 15 that the truck can not get to. This will give us 3/4 lb of nitrogen and about 1 lb of potassium. This will prevent crabgrass from germinating on the golf course. Our next big spread of fertilizer will be in the fall when we will try to get 2 pounds of nitrogen out between September and November.
