The Indian Institute of Soil Science has developed a web-based system to advise farmers on using the right quantity of fertilizers in soils for a particular type of crop. An official release by the ministry of Agriculture says, the system converts the nutrient data into the quantities of main fertilizers like urea, potash and phosphate used by farmers in fields. The software takes into account the soil type in different districts of the country and available nutrient in the soil. It takes into consideration the crop and cropping season in calculating the nutrient requirement. In some cases, it takes care of even different available varieties of main crops. The software can be accessed on www.iiss.nic.in/stcr/mainform.asp
The system is presently available district-wise in 11 states. The states are Andhra Pradesh, Bihar, Chhattisgarh, Haryana, Himachal Pradesh, Karnataka, Maharashtra, Orissa, Punjab, Tamil Nadu and West Bengal.
