Microwave remote sensing and Irrigation management

With the increase in population, demand for food is also increasing.The critical challenges in attaining food security include the conversion of agricultural land to built-up land and diminishing agricultural yield due to several factors such as shortage of water, pests and other diseases, forms some of the critical challenges in attaining food security. These issues can be solved to a great extent using proper irrigation. Farmers should be able to identify the factors affecting yield in near real-time so that it can be rectified before the situation gets worse.

Many times, the spatial-temporal variation of yield is observed in the same agriculture land because of the spatiotemporal variation of soil structure and properties. As water remains one of the limiting factors in Indian agriculture, calculating irrigation requirement of the soil types spatiotemporally would be advantageous. Proper usage of water can increase the yield and crop health. Precision irrigation is the practice of irrigating the crops with the optimal amount of water.

High-resolution soil moisture data calculated using the innovative algorithm developed by Satyukt Analytics Pvt Ltd is used to determine the optimal amount of water required for each crop based on the soil type and properties. Irrigation requirement varies with time and hence near real-time monitoring of the soil moisture, soil type and other agro-hydrological parameters such as evapotranspiration, rainfall, vegetation index etc would help to determine the amount of irrigation required at various seasons.
