Novel Approach towards Controlling and Monitoring Nutrient of Soil in Polyhouse

In modern polyhouse, several sensors are required for its automation. Nowadays soil nutrient problem affects plants growth. In this paper various sensing system have been developed for nutrient testing. This technology combines mapping of PH and electric conductivity for soil nutrient management. In agriculture field water is a main source to increase yield of crop. At present irrigation system is fully automated and controlled by the farmers. The proposed system is controlled and monitored as per soil moisture status. Sensors detect soil moisture, water tank level and depending on that solenoid valve are turned ON/OFF automatically. By using wireless sensor network, all sensors data are stored in database and monitored through local display as well as web service (http client/server)
