How nutrient-deficient are Indian soils?



Facet 1: CSE report flags lousy point out of natural fertilisers, biofertilisers sector in India


Most Indian soils are poor in natural carbon and macronutrients, flagged a brand new report. This signifies that concentrations of natural and pure carbon and macronutrients are each ‘very low’, ‘low’ or ‘medium’ for many soils in India, in accordance with the report by Delhi-based principally environmental think-tank the Centre for Science and Environment.

Further than 50 million soil samples from all through India have been analyzed in the middle of 2015-16 to 2018-19 within the govt-permitted laboratories to appreciate the state of the nation’s soils. 

The Level out of Biofertilizers and Pure and natural Fertilizers in India flagged poor standing of soil total well being and elevating use of chemical fertilizers in India. 

About 85 for each cent of the samples ended up noticed to be poor in pure and natural carbon 97 per cent samples have been poor in accessible nitrogen 83 for every cent have been poor in phosphorus and 71 for every cent in potassium, confirmed the Situation of Biofertilizers and Pure and natural Fertilizers in India

Soils have been poor in micronutrients as properly: About 47 for every cent, 39 per cent, 37 for each cent and 36 for every cent soil samples have been poor in boron, zinc, iron and sulphur respectively. 

How poor are Indian soils in natural and pure carbon, macronutrients and micronutrients?

Natural and pure carbon deficiency is in style all through the state. A minimum of 50 % of the soil samples in 24 states and Union territories have been poor in pure and natural carbon. Of them, seven states have further than 90 for each cent poor samples. Haryana’s soils are essentially the most poor in natural carbon, adopted by people of Punjab, Uttar Pradesh, Rajasthan, Tamil Nadu, Mizoram and Andaman and Nicobar Islands, in that purchase. 

Pure carbon deficiency in soils of states and UTs

Nitrogen, phosphorus and potassium deficiencies have been recorded in at minimal half the samples in 32 states and UTs. 

As a number of as  27 states and UTs recorded nitrogen deficiency in additional than 90 for every cent samples 15 skilled nitrogen deficiency in virtually all (99-100 for every cent) of their samples. These are Andaman & Nicobar Islands, Bihar, Dadra and Nagar Haveli and Daman and Diu, Delhi, Haryana, Kerala, Madhya Pradesh, Manipur, Mizoram, Odisha, Puducherry, Rajasthan, Tamil Nadu, Uttarakhand and Uttar Pradesh. 

Available nitrogen deficiency in soils of states and UTs

As numerous as 19 states and UTs have phosphorus deficiency in further than 90 per cent samples. 

Accessible phosphorus deficiency in soils of states and UTs

As fairly a couple of as eight states and UTs had potassium deficiency in in extra of 90 for each cent samples. 

Obtainable potassium deficiency in soils of states and UTs

That is the second publish in a set on India’s non-chemical fertiliser sector.
