An IoT Based Soil Analysis System for Variable Rate Application

Abstract

Variable Rate Application is a method by which the farming inputs are dynamically calibrated to match the optimum soil conditions. This method has the potential to increase agricultural productivity, reduce input costs and make agriculture more sustainable. In this paper, a study has been presented in which variable rate application method has been compared to common rate application method in terms of yields and inputs utilized. The study used an IoT based soil analysis system that was used to obtain real time measurements of soil moisture, temperature and nutrient content to enable data based modifications of input rates and implementation of variable rate application method.
