Research and Development of an Automatic Fertilizer Applicator for Small Four-Wheel Tractors.

Abstract

This research aims to develop an automatic fertilizer applicator for small tractors. In order to apply fertilizer precisely as desired, Reduce fertilizer loss from sowing methods. This ensures the most efficient utilization of fertilizer. Working of the drill bit machine the drill bit machine creates a hole in the ground that is 10 cm wide and roughly 15 cm deep. After drilling the hole, fertilizer from the fertilizer tank flows into a pipe attached to the drilling unit and is released into the hole. Then comes the cover set. The system controls the rate of fertilizer application and distribution. Using a microcontroller to control the speed of a 12 V 250 W DC motor for controlling the fertilizer distribution at the specified rate. We carried out an experiment where we drilled eight holes around the tree's base, applied fertilizer to them, and covered them. It was found that the automatic fertilizer applicatorwas able to apply fertilizer precisely. The fertilizer amount was set at 1 kg plant-1, the fertilizer application rate was 125 g hole-1, the work capacity was 1.07 rai hr-1, the fuel consumption rate was 2.65 L rai-1, the soil moisture was 15.03% w.b., and the dry bulk densities was 2.13 g cm-3.Automatic fertilizerapplicatorsfor small tractors have a break-even point of 420.35 rai year-1.
