## ANSWER

## MINISTER OF STATE FOR CHEMICALS & FERTILIZERS

## (SHRI BHAGWANTH KHUBA)

(a) to (c):  The Ministry of Chemicals & Fertilizers does not conduct such type of study. However,  Indian  Council  of  Agriculture  &  Research  (ICAR)  furnished  the  following details:

'The nitrogen  use  efficiency  of  nitrogenous  fertilizers  varies  between  30-50% depending on soil type and crop grown. Remaining nitrogen is lost mainly by way of nitrate leaching (causing nitrate contamination in ground water above the permissible limit of 10 mg NO3-N /L).

Thus, ICAR is recommending soil test based balanced and integrated nutrient management practices through conjunctive use of both inorganic and organic sources (compost,  bio-fertilizers,  green  manure  etc.),  split  application  and   placement  of nitrogenous fertilizers, use of slow releasing N-fertilizers, nitrification inhibitors and use of neem coated urea etc.  to avoid such situation.'

(d): The  details  of  top  five  states  using  maximum  chemical  fertilizers,  i.e.  Urea, DAP, MOP and NPK is as under:

| Top five (5) States using maximum quantity of Chemicals Fertilizers 2022-23 (Upto Feb., 2023.)   | Top five (5) States using maximum quantity of Chemicals Fertilizers 2022-23 (Upto Feb., 2023.)   | Top five (5) States using maximum quantity of Chemicals Fertilizers 2022-23 (Upto Feb., 2023.)   | Top five (5) States using maximum quantity of Chemicals Fertilizers 2022-23 (Upto Feb., 2023.)   | Top five (5) States using maximum quantity of Chemicals Fertilizers 2022-23 (Upto Feb., 2023.)   | Top five (5) States using maximum quantity of Chemicals Fertilizers 2022-23 (Upto Feb., 2023.)   |

(e):   Central Ground Water Board generates ground water quality data on a regional scale during various scientific studies and ground water quality monitoring throughout the  country.    These  studies  indicate  the  Nitrate  contamination  which  can  also  be caused by excessive use of Nitrogenous fertilizers.
