Real-time monitoring of soil nutrient analysis using WSN

The agricultural yield primarily depends on soil fertility, the moisture level of soil and use of appropriate fertilisers. In the current scenario, the manual method of measuring the soil nutrients is less accurate because of the time difference of soil sample collected at the field and when it is measured in a laboratory. It becomes necessary to create a smarter agriculture practice through Internet of Things(IoT) to address this challenge. Soil nutrient analysis using wireless sensor networks (WSN) enables various application like remote monitoring of soil fertility, analysis, provide a selection of crop and build irrigation decision support systems. In the proposed system, the wireless sensors measure the macro nutrient of soil and transmit the data to the cloud. The user can view the soil fertility at the convenience on their mobile application. It is possible that the farmer may wish to grow a specific crop based on the economic interest. The software system has the intelligence to recommend the fertiliser that is required to be used to suit the needs of the desired crop, thus improving the quality of the soil and in turn, increase the yield. Overall, the proposed system helps farmers to gather real-time information about various soils, their fertility level, suggest crops and fertilisers at the convenience of the mobile app. Finally, this project effort will help farmers to make the right decision, gain better yield and economic advantage.
