IoT-based Assessment and Monitoring of NPK Content and Fertility Condition of Soil

Since infertile soil is abundant on Philippine land, farmers need to first know the condition of the soil before planting crops on it. The key to good crop production is providing plants with the proper amount of nutrients at the appropriate time. Farmers who are not exposed to contemporary technologies continue to use traditional methods to enhance yield production, which is no longer a highly productive sort of farming. This study aims to create a system that will help farmers and home gardeners assess and monitor the condition of their crops by checking the variables of the soil such as NPK (Nitrogen, Phosphorus, Potassium) content, moisture level, acidity level, and humidity with the help of Internet-of-Things (IoT), which allows farmers to get fast insights on issues before they happen and make informed decisions on how to avoid them. The system also tells you which crop is best for your soil based on how much NPK it has. This information comes from the result retrieved from sensor that this study will use. The researchers used Evolutionary Prototyping in developing the Sensoil Device for the purpose of making the SAMS (Soil Assessment and Monitoring System) system as user-friendly as possible by implementing what the experts and user respondents wanted. The results show that with the implementation of the device, crop growth becomes healthier and faster, and it increases the potential to have a higher yield production that will boost the income generated from the farmlands while reducing unnecessary fertilizer and water use.
