## STATEMENT  REFERRED  TO  LOK  SABHA  STARRED  QUESTION  NO.  492  FOR 27.03.2026  REGARDING 'Impact of Balanced Nutrient  Application'  TABLED  BY SHRI PRAVEEN PATEL AND SHRI RAJKUMAR CHAHAR:

(a): The Cabinet Committee on Economic Affairs (CCEA), on June 28, 2023, approved the 'PM  Programme  for  Restoration, Awareness  Generation, Nourishment, and Amelioration  of  Mother-Earth  (PM-PRANAM). The initiative  aims  to  support  the mass movement initiated by States and Union Territories (UTs) to preserve the health of Mother Earth  through  the  promotion  of  sustainable  and  balanced  fertilizer  use,  adoption  of alternative  fertilizers,  promotion  of  organic  farming,  and  implementation  of  resource conservation technologies.

All  States/UTs  are  covered  under  the  PM-PRANAM  scheme.  Under  the  PMPRANAM scheme, there is a provision to provide incentives to States/UTs for reduction of consumption of chemical fertilizers (Urea, DAP, NPK, MOP) in a given financial year, compared to the average consumption over the previous three years, equivalent to 50% of the fertilizer subsidy saved. Of the total grant, 95% will be allocated to the State, while provided  to  the  States,  65%  is  for  capital  expenditure  (capex)  projects,  preferably  as contributions  to  Centrally  Sponsored  Schemes, and 30% is untied for other activities, including Information, Education, and Communication (IEC) initiatives.

(b): Department  of  Fertilizers  (DoF)  in  collaboration  with  fertiliser  companies,  has launched Maha Abhiyan to  promote  the  adoption  of Nano DAP across  all  15 Agroclimatic zones of the country through consultations & field-level demonstrations. Under the guidance of Indian Council of Agriculture Research (ICAR) and the supervision of ICAR-Krishi Vigyan Kendras (KVKs), IFFCO had conducted 2,500 Nano DAP Farmer Field Trials during Kharif and Rabi 2024-25 and 2,938 Nano DAP Farmer Field Trials during Kharif and Rabi 2025-26 (till 23.03.2026) across 15 Agro-Climatic Zones (ACZs) of the country.

Additionally, DoF  in  collaboration  with fertiliser  companies,  has  initiated  a nationwide campaign for field-level demonstrations and awareness programmes on Nano Urea Plus in  100  districts.  IFFCO  had  conducted 448 Nano Urea Farmer Field Trials during Kharif and Rabi 2024-25 and 484 Nano Urea Farmer Field Trials during Kharif and Rabi 2025-26 (till 23.03.2026) across 15 Agro-Climatic Zones (ACZs) of the country under the guidance of Indian Council of Agriculture Research (ICAR) and the supervision of ICAR-Krishi Vigyan Kendras (KVKs).

The  State  wise,  Agroclimatic  Zone  (ACZ)  wise,  Nano  Fertilisers  Field  Trials, including Nano Urea and Nano DAP are placed at Annexure I (Kharif, 2024  (April to September-2024)) , Annexure II (Rabi, 2024-25, (Oct-2024 to Mar-2025)) , Annexure III (Kharif, 2025   (April to September-2025)) and Annexure IV (Rabi, 2025-26 (Oct-2025 to Mar-2026, as on 23.03.2026)).

(c) and (d): Karnataka  State  Agriculture  Universities  have  undertaken  2  long  term experiments at University of Agricultural Sciences (UAS), Gandhi Krishi Vigyana Kendra (GKVK), Bangalore, which are as under:

(i)  Long  Term  Fertilizer  Experiments  are  under  progress  since  1986  at  All  India Coordinated  Research  Projects  (AICRP)  on  Long-Term  Fertilizer  Experiments (LTFE), UAS, GKVK, Bangalore to study changes in soil quality, crop productivity and sustainability in Alfisols under finger millet-maize cropping system. The results of the experiments are attached at Annexure V .

(ii)Long  Term  Fertilizer  Experiments  are  under  progress  since  1978  at  All  India Coordinated  Research  Projects  (AICRP)  on  Dry  land  Agriculture,  UAS,  GKVK, Bangalore to study the changes in soil quality, crop productivity and sustainability under finger millet monocropping and finger millet-groundnut crop rotation.

In  addition  to  this,  long-term  studies  conducted  by  Indian  Council  of  Agricultural Research  (ICAR)  at  various  locations  across  diverse  agro-ecological  regions  of  the country demonstrate the impact of balanced nutrient application on soil health and crop productivity.  The  findings  indicate  that  recommended  NPK  application  (100%  NPK) improves crop yields by about 20-30 per cent over nitrogen-only use, while integrated nutrient management (100% NPK + farmyard manure) further enhances productivity by 30-50 per cent over control plots. Soil organic carbon is highest under integrated nutrient management, improving by about 0.1-0.3 percentage points over long-term nitrogen-only treatments, indicating  better  soil  health.  Microbial  biomass  carbon  is  also  significantly higher, by 20-40 per cent, under integrated nutrient management compared to chemical fertilizers alone. In contrast, continuous nitrogen-only application leads to declining yields and deterioration of soil properties over time.

Further, under All India Coordinated Research Project on Soil Test Crop Response (AICRP-STCR),  soil  test-based  balanced  fertilizer  prescription  equations  have  been developed for major crops to enable site-specific nutrient management  based on soil fertility  and  farmers'  resources.  Coordinated  programmes  also  promote  balanced fertilization  and integrated nutrient management through training, demonstrations, and awareness activities. Overall, balanced and integrated nutrient application is essential for sustaining soil fertility, improving crop productivity, and ensuring environmental sustainability.

(e): The farmers can purchase their required amount of subsidized fertilizers based on the recommendation of Soil Health Card received by them through any fertilizers retail shop/ Pradhan Mantri Kisan Samridhi Kendra (PMKSK). The subject matter of Soil Health Card falls in the purview of Department of Agriculture & Farmer's Welfare and no such proposal of integrate Soil Health Card recommendations with fertilizers supply plan has yet been received from the administrative Ministry.

(f): Under  the  'Promotion  of  Bulk  Drug  Parks'  scheme,  one  bulk  drug  park  in Jambusar, Bharuch, and Gujarat was approved in FY 2022-23. Financial assistance from the Central Government is provided for creation of Common Infrastructure Facilities (CIF), subject to a maximum of ₹1,000 crore per park, or 70% of the project cost, whichever is lower.

- (a)  Total project cost: ₹2,507.02 crore
- (i) CIF  project  cost:  ₹1,457.01  crore  (₹1,000  crore  is  grant  from  the  Central Government)
- (ii) Physical infrastructure cost (other than CIF): ₹1,050.01 crore
- (b) Area: 2,015.02 acres, at Jambusar, Bharuch District, Gujarat
- (c) Major CIF being developed under the scheme includes steam generation and supply, common effluent treatment plant, centre of excellence, solvent recovery facility, treatment, storage and disposal facilities, raw water supply and effluent collection pipeline, infrastructure of roads and internal  drains.  Common infrastructure of marine discharge and power infrastructure are being executed with state funds.

## Financial & Physical Status:

The  State  Implementing  Agency,  Gujarat  Industrial  Development  Corporation,  as  on 28.02.2026, has utilised ₹341.44 crore out of the two instalments of ₹300 crore each received  as  Central  Grant-in-Aid,  and  ₹206.92  crore  out  of  ₹274.20  crore  from  State funds, towards the development of CIF.

The present status of progress of the CIF under Gujarat bulk drug park is as under:

-  The environmental clearance was granted to the Gujarat Bulk Drug Park in February 2024. All  the  common  infrastructure  facilities  related  civil  tenders,  such  as  road, drainage, water infrastructure, effluent collection and rack system are awarded and approximately most of the work has been completed on site.
-  CIF Utility tenders like Common Effluent Treatment Plant (CETP), Solvent Recovery, Treatment Storage & Disposal Facilities, have also been awarded and a small portion of  the  work  has  been  completed on  site. Tender  of  parking  has been  awarded  in November, 2025.
-  Tender of Steam Generation is released and which is under evaluation.
-  In  addition  to  above  CIF  work,  State  Implementing Agency  (SIA)  has  completed construction of an approach road of 4 km and has initiated the installation of a water pipeline to draw surface water from the Narmada Canal, located approximately 40 km from the Bulk Drug Park site.

## Results of Experiment

1. Incorporation of FYM along with optimal dose of NPK, improved soil physical properties (Soil aggregates, bulk density, total porosity and hydraulic conductivity).

2. The practice of applying only fertilizers has resulted in considerable drop down in soil pH, especially with higher levels of NPK and N alone.

3. Application of FYM as soil amendment is more effective than lime as former has not only moderating effect but also supplies nutrients like N, P, K and other micronutrients.

4. Buildup of available phosphorus is recorded in plots treated with 100% and 150% dose of P while, marginal buildup of K is recorded in plots that received 100% potassium.

5. Reduced level of phosphorus application (50% P) would be beneficial in terms of saving fertilizers as well as sustaining the crop productivity in P buildup soils.

6.  Available S  content in soil markedly increased when SSP fertilizer was given as P source but decreased when treated with DAP. Sulphur deficiency was observed due to continuous application DAP fertilizer as P source.

7. There was a marginal decline of Ca content in soil in all treatments except those treated with lime and FYM.

8. Deficiency of micronutrients is not found as the balanced application of nutrients using organic manure is taking care of micronutrients by mobilization from the reserve source of residual bio-mass added to soil.

9.  Balanced  and  integrated  use  of  nutrients  improved  soil  organic  carbon  status,  the beneficial microbiological population and enzyme activities in soil.

10. The minimum amount (threshold) of carbon required to maintain initial carbon level in soil is dependent on initial content of carbon in soil and climate and it was found to be 3600 kg/ ha/year.

11. Integrated use of inorganic fertilizers and organic manures not only sustained the soil productivity on long term basis but also improved the nutrient use efficiency.

12. The sustainable yield index (SYI) of maize and finger millet over the years is found highest in the plots which received NPK+FYM+lime and 150% NPK, respectively.

13.  Higher  Soil  Quality  Index  is  recorded  in  T10  (NPK+FYM+  lime)  followed  by  T8 (NPK+FYM) treatments and lower SQI is recorded in control and imbalanced treatments.
14. Soil pH, K, Ca, Mg and microbial biomass carbon are important soil indicators to be taken care of for improving soil quality. Practical Significance: Applying the optimal dose of fertilizers integrated with organic sources such as FYM is essential for sustaining crop productivity  and  improving  long-term  soil  health.  Indiscriminate  or  imbalanced  use  of nitrogenous fertilizers drastically reduces yield and leads to significant deterioration of soil health.  Farmers  should  be  discouraged  from  applying  only  nitrogen  and  phosphorus fertilizers (such as DAP and urea) for finger millet. The inclusion of potassium, along with recommended  doses  of  nitrogen  and  phosphorus,  is  crucial  for  achieving  sustained higher yields. The commonly used high-analysis fertilizer DAP should be supplemented with  secondary  nutrients,  as  continuous  reliance  on  DAP  alone  has  contributed  to widespread secondary nutrient deficiencies. Continuous application of the recommended dose  of  phosphorus  has  been  observed  to  cause  soil  phosphorus  buildup.  In  such situations,  applying  half  the  recommended  phosphorus  dose  is sufficient  to  meet  the crop's needs without compromising yield.
