Indian Agri Institute Develops GIS Based Soil Fertility Maps for 19 States29 July 2014
INDIA - Bhopal based Indian Institute of Soil Science (IISS) has developed Geographic Information Systems (GIS) based soil fertility maps of 19 states using data of different soil testing laboratories in the country.
The institute is part of Indian Council for Agricultural Research (ICAR) based in New Delhi, said that the assessment revealed that about 59 per cent, 49 per cent and nine per cent soils are low in available nitrogen, phosphorus and potassium respectively.
The extent of micronutrient deficiency in soil (state-wise) was studied under the All India Coordinated Research Project on ‘Micro and Secondary Nutrients and Pollutant Elements in Soils and Plants’, Dr. Sanjeev Kumar Balyan, Indian minister of state for agriculture and food processing industries said in a statement recently.
The minister said that government through the National Project on Management of Soil Health & Fertility and National Project on Organic Farming promotes soil test based balanced and integrated nutrient management and use of organics (manure/composts, bio fertilisers etc.) to prevent decline in fertility of agricultural land and to improve soil fertility.
The Government uses science and technology, namely, Geo-referenced soil sampling technique, GIS based software for soil fertility mapping, prescription equations for soil test based fertilizer recommendation, liquid bio fertilizer formulations, soil genomics, bio-enriched composting/vermicomposting, fertigation and Resource Conservation Technologies (RCTs) for improving fertility of soils. Besides, nano technology application is also being explored, the minister adds.
However, the minister did not revealed the name of the states that has been mapped by the IISS.
