GIS Based Soil Fertility Maps Prepared for 19 States

Indian Institute of Soil Science has developed GIS based soil fertility maps of 19 states using data of different soil testing laboratories in the country. The assessment revealed that about 59, 49 and 9% 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’.

The 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, biofertilizers 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 biofertilizer 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.

This information was given today by Dr. Sanjeev Kumar Balyan, Minister of State for Agriculture and Food Processing Industries in a written reply to Rajya Sabha questions.
