Development of Intelligent Sensor Based System for Monitoring and Control of Nutrient Supply in Root Crops

In today's era, Agriculture plays an important role in the economic progress of any country. The soil fertility and moisture level will have a major impact on the crop yield. Normally, fertilizers are suggested based on the nutrients present in the soil. Manually measuring the soil nutrients in the soil is a time consuming. Usually most of the farmers avoid soil testing in the laboratory and encourages to promote the same crop in the field continuously, so as a result the fertility of the soil will be lost. For the benefits of farmers, a precise agriculture method system has been introduced with the help of wireless sensor networks, the benefit of this system is remotely monitoring the soil nutrients, which are available in the soil, that is the three main nutrients, nitrogen, phosphorus and potassium which contributes to major nutrients of the soil and other parameters namely moisture level of the soil, pH of soil, humidity of soil, sunlight, temperature and TDS. pH level accounts for the stability of the growth of the plant. TDS value determines the purity of water supplied to the root crops. Sunlight is an essential parameter in the growth of the plant which is monitored in this system. This data is copied and transmitted to the cloud server so the noted values of the nutrients are displayed in the mobile application server. The proposed Internet of things (IoT) software system has the intelligence to suggest the amount of water and fertilizer that will enhance the soil's quality and guarantee the best possible crop development.
