Portable Soil Fertility Level Detector Based on Electrical Parameter Measurement

The application of the Internet of Things (IoT) represents a significant innovation in implementing Industry 4.0 to support precision agriculture, thereby enhancing production capability and quality. In precision agriculture, a common issue is the difficulty in determining soil fertility levels, which leads to suboptimal responses such as inappropriate fertilization. Traditional methods of measuring soil fertility, which involve taking soil samples to a laboratory, require considerable time and financial resources. Consequently, there is a need to develop a tool that is easy to use, fast, and cost-effective for determining soil fertility. A promising alternative is the approach of measuring electrical parameters, specifically electrical conductivity, to ascertain soil fertility levels. In response to this need, a precise and portable device for measuring soil electrical parameters has been developed. This tool significantly reduces the time required to measure soil fertility levels, as it eliminates the need for laboratory analysis of soil samples, thus making the process more economical.
