IIT Kharagpur Innovates DGPS-Enabled Soil Mapping Tech for Effective Fertilization

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…

Ammonia Hotspot Trends in India – First-time observations from India

Indo-Gangetic Plain an atmospheric ammonia hotspot but India‚Äôs overall trends look promising Agro fertilizers containing high levels of ammonia have long been designated as a hazardous material for human health. For the first time in India, the seasonal and inter-annual variability of atmospheric ammonia emitted by the agricultural sector has been analyzed by researchers from IIT Kharagpur in collaboration with IITM Pune and European researchers. And the results are in agreement with the long-held apprehension of global environmentalists - the Indo-Gangetic Plain (IGP) is indeed the global hot-spot of atmospheric ammonia (NH3) due to intense agricultural activities and fertilizer production…
