Franklinton, LA | I would suggest measuring the total spread of the material with the aircraft flying into the wind. You will have the most even coverage if the swath width is 40 - 50% of the total spread. This overlap will reduce the problems caused by variations in flying height, fertilizer not flowing evenly out of both sides of aircraft metering gate, changes in velocity of cross wind and numerous other variables.
The total spread will be reduced if the fertilizer is moist or sticky. You will get a wider spread if the fertilizer is dry.
Opening the aircraft metering gate will increase the amount of fertilizer flowing into the spreader. Increasing the amount of fertilizer in the spreader will reduce the velocity of the air in the spreader. The maximum spread will be reduced as the air velocity is reduced and the fertilizer flow rate increases. In other words the swath should be reduced as the application rate increases.
