northwestern middle tn | Checking Dry Fertilizer Rates (U.S. Measurement)
To check the exact number of lb. of fertilizer that will actually be delivered for 30 in. row spacing, proceed as follows:
Remove one hose from either fertilizer hopper and attach a plastic bag or other suitable container, under the opening in the hopper. Engage the fertilizer attachment and drive forward for 174 ft. Weigh the amount of fertilizer caught in the container (in lb.) and multiply that amount by 100. The result will be the lb. of fertilizer delivered per acre when planting in 30 in. rows.
NOTE: For 36 in. rows, drive 145 ft. For 38 in. rows, drive 138 ft.
This is the most surefire way of getting the rate you want applied. The charts cannot take into account different densities of the different fertilize mixes we all use.
