A Design of an Automated Fertigation System Using IoT

Abstract

In Sudan, unfortunately, farmers still use traditional methods of farming management leading to inputs wastages and low production due inaccurate types and amount of fertilizers applied to the field which depends upon soil analysis and plant yield. And the process of determining the type of fertilizers according to the soil analysis results takes a long time. The main objective of this paper is to overcome the above-mentioned problems by designing an automated fertigation system based on the internet of things (IoT). Water use efficiency (WUE) is achieved and controlled by using moisture sensor when the soil moisture drops below 30% is opened and closes when it reaches 70% (preset data according to plant needs). The fertilization control is the process of adjusting the potential of Hydrogen (pH) and soil electrical conductivity (EC) as in preset database and thereby acidity and alkalinity. In addition to that, the plant root zone is controlled as required. When the system is applied, it improves water and fertilizer use efficiencies and thus saves effort, money, time, energy, increases production, and productivity.
