DGPS based technology to Improve fertilizer application

DGPS based technology to Improve fertilizer application

Geospatial mapping is a buzzword now with the Govt. of India liberalizing the industry. There's another facet of mapping which may transform the food safety program of India; dirt maps, which might be obtained using differential GPS (DGPS), developed by investigators in IIT, Kharagpur for a varying rate of fertilization program in farmlands.

Spatial variations in soil type and mineral material in big agricultural tracts are a frequent occurrence that contributes to a dynamic demand for sources like fertilizers, pesticides, pesticides as well as water. Farmers are collecting data on those variants through soil evaluation by local bodies or installing detectors to collect the information in real time. On the other hand, the closeness of this applicator automobile to the detector hinders real-time sensor-based information processing and compost program.

The publication technologies, developed by researchers in IIT, Kharagpur, is targeted towards efficient utilization of Nitrogen, Phosphorous and Potash (NPK) for automatic soil nourishment management by bypassing both manual labor based surgeries or sensor-based fertilization technology that are still under development, say investigators.

The soil map could be reproduced for agricultural plots according to soil tests that could be carried out at district management levels or from private labs. This information when fed to the DGPS module will soon be available to farms utilizing the GUI installed-applicator.

Explaining the procedure Prof. Tewari stated, "We split one hectare of land into 36 grids together with the nutrient need of every grid fed from the dirt map. The compost applicator vehicle, fitted using a DGPS module also GUI allowed Microprocessor cum Microcontroller, can get this map and calculate in real time the varying speeds in the fertilizer program operate." He added remarking how this technology may reduce the price of fertilizer program by enhancing the efficacy of this project and reducing manual labor.

"The machine can detect the area grids in real time using a length-wise precision of 16 cm towards the east and also breadth-wise precision of 20 cm towards the north. Application of these desirable amount of NPK exactly at a particular place will improve crop production and prevent environmental degradation. This technology would have the ability to reduce 30 percent of fertilizers used in manual approaches thus ensuring considerable economies in source software," explained Prof. Tewari.
