The KGP Chronicle (February 21, 2021)

Geospatial mapping is a buzzword today with the Govt. of India liberalizing the sector. There is another side of mapping that could transform the food security program of India; soil maps which could be accessed using differential GPS, developed by researchers at IIT Kharagpur for a variable rate of fertilization application in farmlands. The novel technology is aimed towards efficient use of Nitrogen, Phosphorous and Potash for automated soil nutrition management by bypassing both manual labour based operations or sensor-based fertilization technologies which are still under development.
Spatial variations in soil type and mineral content in large agricultural tracts are a common phenomenon that leads to a dynamic need for resources such as fertilizers, pesticides, herbicides and even water. Farmers have been collecting information on these variations through soil tests by local bodies or installing sensors to collect the data in real-time. However, the proximity of the applicator vehicle to the sensor hinders real-time sensor-based data processing and fertilizer application. (Read More)
