Data: Chemical Fertilizer consumption increased by about 16% in the last six years

0

Data shared by the government recently indicates that the consumption of chemical fertilizers has increased by around 16% between 2015-16 & 2020-21. From about 510 LMT in 2015-16, the consumption increased to 590 LMT as per provisional figures for 2020-21. Even the consumption of chemical pesticides has increased during this period. 

Recently, fertilizer manufacturers in India including the Indian Farmers Fertilizers Cooperative Ltd. (IFFCO) announced a steep hike in the price of agricultural inputs such as di-ammonium phosphate (DAP) as a result of increased prices of raw materials in the international market. In the past few months, the prices of potash, DAP, phosphoric acid, etc. have also increased significantly forcing the fertilizer makers to hike the prices of the de-controlled nutrients. However, the Minister of State for Chemical and Fertilisers, Mansukh Mandaviya announced that the manufacturers have been asked not to increase the prices of all fertilizers. IFFCO has also clarified that there is enough material with old rates which will be sold at the old rates to farmers. Further, IFFCO has stated that the new prices are only tentative and yet to be finalized by companies. 

Multiple factors determine fertilizer usage 

Consumption of fertilizers and pesticides is determined by multiple factors such as area of land under cultivation, the type of crop, cropping pattern and cropping intensity, soil type and its condition, agro-climatic conditions, the ability of farmers to purchase, irrigation, and others. The Department of Agriculture & Co-operation and farmers Welfare also carries out assessments to determine the requirement of chemical fertilizers- Urea (Nitrogen), DAP, MOP (Muriate of Potash), and NPKs (contains major nutrients- Nitrogen, Phosphorous, and Potassium) on a season-to-season basis, taking into consideration the above-mentioned factors and finalizes the requirement of for each season in consultation with the states. Bi-annual zonal conferences are held before the beginning of each cropping season i.e., Kharif (April to September) and Rabi (October to March). The allocation of fertilizers to states is an outcome of this process. 

Urea is the most consumed fertilizer 

On average, India consumed about 500 LMT of fertilizer per year in the last 10 years. The government recently provided year-wise consumption data in the Rajya Sabha, showing the trend in the quantity of chemical fertilizers used in India since 2015-16. As per the data shared, Urea is the most consumed fertilizer with around 300 Lakh Metric Tonnes (LMT) being consumed each year, accounting for 55 to 60% of the chemical fertilizer consumption in the country. Between 2016-17 and 2019-20, there has been a steady increase in the consumption of Urea, DAP, and NPKs. The data for 2020-21 is provisional and is available up to February 2021. 

Even though the data is only up to February 2021, the consumption of DAP and NPKs is already the highest in 2020-21 in the six-year period from 2015-16 to 2020-21. The final quantity of urea consumed in 2020-21 might also cross the 2019-20 levels making the consumption highest in 2020-21. 

India’s average chemical fertilizers consumption has increased

A five-year trend in the average per hectare consumption of fertilizers across states (in kg/hectare – kg/ha) was also presented in the Rajya Sabha by the government. According to this data, the average consumption of major chemical fertilizers at the national level was 135.76 kg/ha in 2015-16 which dropped to 123.41 kg/ha in 2016-17. However, since then, the consumption has gradually risen to 133.44 kg/ha in 2019-20 at the national level. 

Fertilizer Consumption: Bihar consumed most while Kerala least in 2019-20

Bihar (245.25 kg) topped the list in 2019-20 with respect to the per hectare consumption of fertilizers, closely followed by Puducherry (244.77) in spite of its small size. Punjab, Haryana, and Telangana are among the top five states/UTs which have all reported consumption of more than 200 kg/ha in 2019-20. These five states/UTs have also consistently reported consumption of more than 200 kg/ha in the five-year period from 2015-16 to 2019-20. Puducherry had consumed nearly 406 kg/ha of fertilizers 2015-16. These five states constitute the top five in no particular order since 2017-18.  

On the other hand, Kerala and Jammu & Kashmir are among the major states/UTs that have the least fertilizer consumption. Both these states/UTs have reported a significant drop in the average usage of fertilizers in the five years. Kerala reported a decline from 87 kg/ha in 2015-16 to 36.49 kg/ha in 2019-20 while Jammu and Kashmir reported a decline from 105.49 kg/ha to 40.85 kg/ha during the same period. Maharashtra, Madhya Pradesh, Chhattisgarh, and Jharkhand are major states which have consistently reported fertilizer usage below the national average during this five-year period. Madhya Pradesh, Uttar Pradesh, and Delhi are among those states/UTs that have witnessed a steady increase in average fertilizer consumption in these five years. 

Maharashtra and UP top the list of pesticide consumption in the last five years

The consumption of chemical pesticides has also been on a rise in India. Between 2015-16 and 2019-20, there has been a growth of 8.78% in the overall consumption of pesticides in the country, from 56,720 metric tonnes (MT) to 61,702 MT.  Maharashtra and Uttar Pradesh are the major consumers of chemical pesticides in the country over the last five years. The consumption in Maharashtra increased from 11,665 MT in 2015-16 to 12,783 MT in 2019-20. The consumption in Uttar Pradesh had also increased from 10,457 MT to 12,217 MT during the same period. Together, the two states accounted for 40% of the total consumption reported at the national level. Punjab had the third-highest consumption with an average of 5,592 MT consumed every year. UP and Telangana reported a steady increase in pesticide consumption in contrast to Andhra Pradesh, where the pesticide consumption has decreased by almost 40% in these five years. 

The lowest usage of pesticides was in the small states. Goa had the least consumption with 30 MT in 2019-20 as compared to 48 MT in 2015-16. Puducherry too had low consumption with 40 to 43 MT consumed each year. The northeastern states of Meghalaya and Sikkim were marked as ‘Organic States’ in the response provided in the parliament.

Bio-pesticides usage is on the rise with Maharashtra being highest consumer

The government is promoting the use of bio-pesticides through various schemes. However, the increase in consumption has not been dramatic. The consumption of bio-pesticides at the national level stood at 8,847 MT in 2019-20 as against 6,148 MT in 2015-16. Though there has been a continuous increase in biopesticide consumption, the quantity is still very less compared to conventional chemical pesticides. 

Data shows that Maharashtra was the major consumer of bio-pesticides during the last five years. But the state’s consumption has declined since 2016-17. It had consumed 1,454 MT in 2016-17 accounting for one-fifth of the consumption at the national level. However, consumption came down to 1,082 MT in 2019-20, accounting for 12% of the total national consumption. Other major consumers of biopesticides are West Bengal, Tamil Nadu, Kerala, and Chhattisgarh. Rajasthan, reported an almost 100 times increase in the consumption of biopesticides in 2019-20, as compared to the previous years. The annual consumption was below 15 MT between 2015-16 to 2018-19 and jumped to 929 MT in 2019-20.

The Central Government has taken measures to check the usage of chemical fertilizers

The Indian Council of Medical Research (ICMR) under the Ministry of Health & Family Welfare has initiated a multi-centric study to assess exposure & the health effects of pesticides. Furthermore, under ‘Sub-Mission on Plant Protection and Plant Quarantine’,  training is being imparted to state extension officers and farmers on ‘Integrated Pest Management’ where judicious use of chemical pesticide as a last resort, safety in the use of pesticides, alternate tools for pest management viz; cultural, physical, mechanical methods of pest control as well as the use of bio-pesticides and bio-control agents, effects of pesticides on natural enemies of pests, do’s and don’ts of a pesticide including proper application equipment and the technique are highlighted.  

All India Coordinated Research Project on ‘Long Term Fertilizer Experiments’ over five decades at fixed sites revealed that continuous use of nitrogenous fertilizer alone had a deleterious effect on soil health and crop productivity showing deficiencies of other major and micro-nutrients. Even with recommended doses of NPK and more, deficiency of micro and secondary nutrients has become yield-limiting factors over the years. Following this, the ICMR has recommended soil test-based, balanced and integrated nutrient management through conjunctive use of both inorganic and organic sources of plant nutrients to prevent damage to natural resources. The government is also advocating the concept of balanced and judicious use of fertilizers in conjunction with biofertilizers, organic fertilizers, farmyard manure, etc. 

Studies have emphasized on the excessive usage of nitrogen fertilizers in India

According to the Impact Study of Soil Health Card Scheme conducted by MANAGE, Hyderabad, India consumes about 25.6 million tonnes of fertilizers, mostly Nitrogen (17 million tonnes) followed by Phosphorous (6 million tonnes) and Potassium (2.5 million tonnes). The current NPK ratio is 6.7:2.4:1, which is highly skewed towards Nitrogen as against the ideal ratio of 4:2:1. The variation in usage across states is also huge, as observed in this story. Furthermore, India spends about ₹ 1 lakh crore on fertilizer subsidies every year. The subsidy amount is about ₹ 6,500/ha of the net cropped area and about ₹ 7,000/farmer which has resulted in excessive use of fertilizers, especially nitrogen, at the cost of micro-nutrients and manure. This excessive and imbalanced usage has also resulted in the decline in the amount of food grain produced per kg of fertilizer applied from 13 kg in the 1970s to just 4 kg in 2010, as per the MANAGE report. 

Similar observations about farmers favouring a particular group of nutrients more were made by a standing committee report on fertilizer consumption tabled in 2020 which stressed the need for educating farmers for using soil-specific fertilizers. The committee suspected that the skewed usage was because of inappropriate marketing of certain fertilizers which fetch them a higher subsidy.
