An important consideration regarding the application of a grain protectant with a grain auger is calibration. The illustration below shows the correct position in which to place an applicator. The correct amount of chemical must be applied to the grain mass to achieve the best results. The following procedure will give an estimated starting point for both commercial and homemade applicators of the flow drip type.
Refer to the owner’s manual for the auger capacity or determine the capacity by recording the amount of material augered over a specific time period. The accompanying table can also be used to estimate auger capacity if the auger size and speed is known. Find the auger capacity and locate the number of ounces of liquid delivered per minute at the desired application rate. Setting the applicator to deliver this amount of liquid in a 1-minute time period will establish a starting setting. Check the amount applied per 1,000 bushels throughout the application operation to ensure correct rates.
