3 3 Fertilizers : Catalysts and Derivative of Agricultural Growth-A Symbiotic Relationship

4 Fertiliser Consumption ('000 MT) FERTILIZER CONSUMPTION & FOOD GRAIN PRODUCTION Foodgrains Production ('000 MT) India has accorded high priority to use of fertilizers for achieving selfsufficiency in food-grain production and stipulated growth in other crops Fertilizer consumption (N+P+K) Foodgrain production 4

5 Cereal yield (mt ha-1) Nutrient vs. Yields Globally, Fertilizers account for almost 50% of the crop productivity. Some Countries like USA get much higher crop yields than India at the same 9level of nutrients as N,P and K applications in India are highly imbalanced? Fertilizer policies highly skewed towards N in India US Germany y = x x R² = China India 1 0 * Nutrient consumption are average of * Note that total nutrient application refers to all crops N, P 2 O 5 and K 2 O application (kg ha-1) Source: FAOSTAT for yields; IFA for nutrients (total nutrients to cereal yield is an inaccurate indicator) 5

13 13 LANGUAGES AND CULTURAL Kashmiri & Dogri DIVERSITY India has huge cultural and ethnic diversity. Any Communication Message has to be in more than 25 Languages /dialects to reach every nook & corner of the country

14 Rainfall Pattern and Seasons in India Rainfall Amount Percent of Area Receivin g Rainfall Rainfall Season Duration Dry (0-750mm) 30 Pre-Monsoon March-May 10.4 Medium ( mm) Medium ( mm) Assured (Above 2000mm) India has only about 2% of total global water. However, it has to support about 17% of global population. Rainfed area accounts for 34% of the total cultivated area, hence good monsoon is critical for Indian Agriculture 42 South- west Monsoon June-Sept Post-Monsoon Oct-Dec Winter or N-E Monsoon January- February Percent of Annual Rainfall Total Total

15 15 IRRIGATION IN INDIA BY SOURCES 45 % Irrigated Area by Source Canals Tanks Wells Tubewells Other Sources Due to water scarcity, protective irrigation methods like drip, sprinkler irrigation systems, are becoming popular particularly in Southern and Western states

19 Production, Mtons Potential Impact of Climate Change on Wheat Production in India Present ~96 million t Almost 25% reduction in wheat production expected in next 50 years or so due to temp. rise in winter Year Source: Aggarwal et al. (2002) 19

20 Projected impacts of climate change on Indian agriculture Cereal productivity to decrease by 10-40% by Greater loss expected in Rabi. Every 1 o C increase in temperature reduces wheat production by 4-5 million tons. This is mainly due to poor tillering and grain filling at higher temperatures. Increasing temperature would increase fertilizer requirement for the same production targets as the fertilizer use efficiency is expected to decrease. Gaseous and leaching N losses from urea, etc may increase and so may be the K leaching losses, thus further decreasing the fertilizer use efficiency of N and K fertilizers. However, P use efficiency may slightly improve with rise in temperature, particularly in Rabi season crops. More demand for N and K fertilizers. 20

21 5. Climate Change is a real threat. Crop production technologies need to be modified, accordingly. 21 Thus, Challenges before the Indian Agriculture: 1. Keep pace with increase in population. 2. Provide diverse food for fast urbanization. 3. Increase in food production need to be vertical as little scope for horizontal expansion. 4. Sustain soil and crop health for the future.

30 Fertiliser Use by Crops in India (Kg/ha) K is mostly used in Horticultural and plantation crops and food crops get smaller K doses. While, P is applied to almost all crops equally. Much more N is applied to Food crops. N (kg/ha) P2O5 (kg/ha) K2O (kg/ha) Source: Adapted from All-India Report on Input Survey, , DAC, Agricultural Census Division 30

31 Percent P and K Consumption in India ( )- Regional Variation P K Region P 2 O 5 (kg/ha) North 43 8 East West 26 8 South K 2 O (kg/ha) North East West South In South, more K is used due to the tropical climate, more soils deficient in K and mostly plantation crops like banana, tea, coffee, spices, rice, sugarcane, etc are grown. Use of N is almost similar in all the regions, except the dry-land, rainfed areas 31

32 32 NPK Use in India-Some Key Issues 1. NPK fertilizer use in India is highly imbalanced. Farmers tend to over-apply and misuse Urea, being the cheapest fertilizer. 2. That leads to very low N use efficiency, from <20% in low land rice to 40% in upland crops which leads to severe N losses and environmental pollution issues like Nitrate leaching in water and ammonia and nitrous oxide gaseous pollution of air. 3. P use is many a times limited, however, some farmers also tend to use P in excess, like potato farmers in West Bengal sometimes overuse P through K use is very limited except the rice, plantations, horticultural crops, sugarcane etc. 5. Research trials have proved that N fertilizer use efficiency can be significantly improved with balanced fertilization of P and K.

33 33 Some Emerging Issues Current price policy favors N over P and K - in comparison to the agronomic value of P and K. Wheat, maize and sugarcane need more focus every where while rice in Northern states need more attention for K management as K balances are much more negative here. Continuous K mining may lead to irreversible damages to soil health in the long run. Benefit from the higher nitrogen use efficiency with K use is tremendous-even modest 10% increase will save 1.7 million t N which will further save the environment. Effective and innovative means to reach farmers about the economical, quality and stress resistance benefits of K is need of the hour.

34 34 Innovations and Positive Developments Much greater awareness of the need for addressing the distress of farmers / rural India at the highest level. Doubling Farmers Income a National imperative. Much higher Government outlay on production credit for farmers. Private investment in agriculture increasing with many Corporates going for contract-farming. Much greater emphasis on Water use efficiency Drip Irrigation and Sprinkler Irrigation. Education levels of farmers going up who are taking up cultivation of exotic vegetables & fruits with innovation like Green House, Poly House etc. fetching higher returns / income. Such farmers becoming role models.

39 kg paddy Fertilizer and Paddy Prices- Economics over time in India Now, almost 3 and 1.25 kg paddy required to buy one kg of P and K, respectively while only 0.8 kg required to buy one kg N.

50 Conclusions and Suggestions: India has the potential to grow the consumption of P & K Fertilizers very substantially over the current levels at existing Government recommendations. While there is an effort to limit the growth of N. The Fertiliser recommendations will need to be revised in due course based on Nutrients uptake by crops and their replacement to maintain the soil health. With negligible domestic commercially exploitable sources, the growth in demand of all three Nutrients will have to be met through imports be they raw materials, intermediates or finished fertilizers. 5 0 Indian Fertilizer Subsidy is not elastic and price increases passed on to the farmers, will destroy demand. 50

51 Conclusions and Suggestions: India needs to be treated as an extension of their own home market by large long term players with responsible pricing for sustained growth in demand. Possibilities exist to increase fertilizer use efficiencies across the board. It is possible to get much higher agricultural output with only little increase in fertilizer use but more importantly balanced use. The need for extension & promotional activities in India including basic research, will always be there more so for P & K. Fertilizer producers / exporters with long term stake in India should share this responsibility
