To an applause from the audience that comprised of high officials, His Excellency the President determinedly declared that import of inorganic Fertilizers will be “banned” in the near future to “protect” Sri Lankans from the adverse effects of such chemicals on the “health” of the larger population. That was on 22nd April 2021. Cabinet of Ministers approved the proposal of the President to ban all imports of inorganic fertilizers and going one step further, agrochemicals, with immediate effect on 26th April. President reconfirmed the ban at another meeting on the 29th April and appointed a committee to carry out his decision. Finally, the Prime Minister as the Minister of Finance, published a gazette notification on the 6th May legalizing the imposed ban. This sealed the fate of agriculture in Sri Lanka that can have devastating consequences on the food security while all other nations in the world are increasing domestic production of food during the pandemic.
President further stated that Organic/Carbonic Fertilizers will be made available to the farming community under the fertilizer subsidy scheme and any crop losses by adopting organic agriculture will be monetarily compensated with the savings from chemical fertilizer import ban estimated at 80 billion rupees. Well said! On page 39 of the manifesto “Vistas of Prosperity and Splendor”, it was stated that the entire Sri Lankan agriculture will be promoted to use organic fertilizers during the next ten years. It is now fast-tracked and a complete ban on import of inorganic fertilizers and agrochemicals is imposed with immediate effect. The first country in the world to do so and the President seems to be proud of this “achievement”!
What is Organic Agriculture?
“Organic agriculture is a holistic production management system which promotes and enhances agro-ecosystem health, including biodiversity, biological cycles, and soil biological activity. It emphasises the use of management practices in preference to the use of off-farm inputs, taking into account that regional conditions require locally adapted systems. This is accomplished by using, where possible, agronomic, biological, and mechanical methods, as opposed to using synthetic materials, to fulfil any specific function within the system.” (FAO/WHO Codex Alimentarius Commission, 1999).
Above is the definition of Organic Agriculture well-described by the Food and Agriculture Organization of the United Nations.
Organic share in the world agriculture and the targets in Sri Lanka
IFOAM Organics International published in February 2020 states that 71.5 million hectares of worldwide farmland are organic. This is a mere 1.5% of global farmland. The countries with the largest organic share are Liechtenstein (38.5 percent), a tiny 160 square kilometer country with a population of less than 40,000 and a per capita GDP (Gross Domestic Product) of US$ 98,500, Samoa (34.5 percent), landmass of 2,842 square kilometers with a population of little over 200,000 and a per capita GDP of nearly US$ 6,000 and Austria (24.7 percent), 83,879 square kilometer country with nearly 9 million people and a per capita GDP of over US$ 50,000. In sixteen countries worldwide including the above three, 10 per cent or more of all agricultural land is organic. This is the result of the hard work done by those governments and organizations such as IFOAM in the past 3 to 4 decades. (IFOAM was established in 1972.) In the United States, extent of organic farms is less than 1%.
Can Sri Lanka with a population of nearly 22 million and a landmass of 65,000 square kilometers and a per capita GDP of less than US$ 4,000 be 100% organic overnight? A question to which the promoters of “Be Organic, Ban Chemical Fertilizers and Agrochemicals” campaign should provide an answer.
Organic Agriculture and its overall impact on crop yields
In 2019, Professor Holger Kirchmann of Swedish University of Agricultural Sciences in Uppsala wrote in his paper “Why organic farming is not the way forward”, that yields of organically cropped legumes were 20% and nonlegumes 40% lower than those of conventionally grown crops. Over all crops, the organic yield gap was 35%. Based on the Swedish statistical data, the condition to compensate for a 35% yield gap would mean increasing the arable land by about 50%.
The above statistics are from a research conducted in Sweden, a temperate country where relative humidity and temperature are much lower than those of tropical Sri Lanka that provides a comfortable breeding ground for pests and diseases due to yearlong high temperature and relative humidity. Unless the so-called organic crops are given a dose of inorganic fertilizers and agrochemicals “during the nights”, the overall impact on yield in Sri Lanka could be 50% or more. Can Sri Lanka double the cultivated land extent of 2.3 million hectares to compensate for the loss of 50% yield by going totally organic overnight? In contrast, a pest attack can have devastating results of even a 100% yield loss. As the President suggested, the farmers will be monetarily compensated for yield loss. But what about the food security? Will the country have sufficient food to feed 22 million? Would the saved 80 billion rupees be sufficient to import food and pay compensation to farmers? Professionals have predicted a bill of 800 billion rupees to import food to meet the gap.
Where is the actual problem?
Sri Lanka spends nearly 60 billion rupees on fertilizer subsidy and import of conventional first-generation fertilizers such as urea, triple super phosphate and muriate of potash costs the country nearly 300 million US Dollars annually. But the quality assured second or third generation fertilizers such as compound, slow release and controlled release types are hardly being imported to the country. Nearly a million metric tons of first-generation fertilizers are imported to the country while a mere 35,000 Metric Tons are imported from the second and third generation fertilizers. Moreover, most of the first-generation fertilizers are imported through tender procedures and cheapest and lowest quality fertilizers are supplied to the farming community under the subsidy scheme. Second and third generation fertilizers do not come under the subsidy scheme and therefore, a credible comparison of high-quality fertilizers and conventional types cannot be done. In contrast, world agriculture is fast moving away from conventional fertilizers and embracing hi-tech second and third generation fertilizers.
There is no doubt that the farmers are using excessive volumes of fertilizers due to two reasons. Firstly, because it is given at a highly subsidized price and secondly because the supplied fertilizers are of very poor quality. This has pushed us to use 287.2 Kilograms of fertilizers per hectare of cultivated land, the highest in the region. Problem lies here, not in the use of inorganic fertilizers.
In the case of agrochemicals, the environmental pollution due to excessive usage takes place due to lack of knowledge due to extremely poor agricultural extension service in the country. The farmer’s “extension agent” is the retailer of agrochemicals who either recommends a cocktail of products or sells the product that gives him the highest sales commission.
Can organic/carbonic fertilizers totally replace inorganic fertilizers?
So-called organic fertilizers are defined as organic manure due to their very low nutrient contents. A kilogram of urea contains 460 grams of nitrogen or 46% whereas a kilogram of compost contains 30 grams of nitrogen unless the manufacturer “adds” urea solution during the manufacturing process. Farmer has to add 15 times more manure to obtain the same quantity of nitrogen that is given by urea. Moreover, only 3% of the nitrogen applied by way of compost is readily available to the plant. The balance 97% will have to be broken down by soil microorganisms and will be available within 12-18 months. Same scenario prevails with the other major nutrients, phosphorous and potassium. The best compost manure can have a NPK ratio of 3 : 2.5 : 1.5 unless inorganic fertilizers are added.
Can a farmer apply around 5 to 6 Metric Tons of organic manure to every hectare? Assuming it is done, the total annual requirement of organic manure in the country will be a massive 11.5 million metric tons. Can this be supplied? The State Ministry in charge of fertilizers assure to “import” organic manure in case of a shortfall. What about the pathogens coming along with imported organic manure? Yet another “disaster” in the making. Another pertinent question would be the inapplicability of organic manure in modern hi-tech such as protected agriculture, drip irrigation etc. that were “promised” to be promoted through “Vistas of Prosperity and Splendor”.
Major portion of conventional fertilizers applied to crops is lost due to leaching, evaporation, runoff etc. that pollutes the environment. In developed and many developing countries, the impact of inorganic fertilizers on the environment is arrested by introducing quality assured second and third generation fertilizers along with advanced technologies such as fertigation (fertilizing through drip irrigation systems), using artificial intelligence and drone technology to spot pests diseases and deficiencies of crops to minimize the use of fertilizers and agrochemicals by spot applications.
Therefore, the solution to avert environmental impact and health hazards to the farming community and the general public from inorganic fertilizers and agrochemicals is not an arbitrary, sudden and mischievous ban but the introduction of high quality second and third generation fertilizers replacing the first generation fertilizers through the private and public sector organizations and streamlining the agricultural extension service to promote judicious use of agrochemicals, perhaps as a public private partnership with the like-minded private sector companies and institutions.
Going 100% organic is a populist idea and such a decision will get instantaneous and sensational support from the general public who are not conversant about the short, medium and long term effects of such a decision. While no country has achieved 100% organic status, small number of nations (16) that have got over 10% of their arable lands under organic agriculture have taken decades to achieve such status.
The decision to immediately ban imports will have devastating repercussions and inevitable food security issues in a few seasons, perhaps leading to a famine in the country. Pundits who promoted this would not be there to answer the public when it happens, and the government will solely be answerable for its decision.
