Nano-Urea: A solution to presentfertiliser crisis?
By R.S. Dharmakeerthi
Professor in Soil Fertility and Nutrient management

Safeguarding the food security is a prerequisite for ensuring national security. We can produce enough food or generate enough foreign exchange to purchase food to achieve food security. If we fail to secure these two, we will have to abide by the conditions set forth by other countries. Under the current global geopolitical battle to secure safe spaces, the super powers will always look for opportunities that they can capitalise in countries that are strategically important such as Sri Lanka. The current fertiliser crisis in the agriculture sector of Sri Lanka is making us even more vulnerable.
Organic Agriculture Mania
On 27 April, the Cabinet took a bold decision to ban the use of agrochemicals, almost overnight, to provide the nation with safe and healthy food. Recently, Senior Professor Udith Jayasinghe Mudalige, the Secretary to the Ministry of Agriculture, has gone on record admitting that the sudden 100% organic agriculture was based on the wrong advice. If someone can mislead a government on a matter related to national security, then there must be something terribly wrong. The authorities now say a phase-out transition to 100% organic agriculture within a period of 3-5 years could have been the best policy. One could see the determination of the government to go for 100% organic agriculture. There are enough scientific publications that insist that crop yield will be reduced by 20-25% on average in organic agriculture leading to food insecurity of a country. Therefore, not the transition period, but the concept of 100% organic agriculture itself is a threat to national security.
Chemical fertilizer is not poisonous
The government still believes that chemical fertilisers are poisonous and have led to a number of non-communicable diseases including the chronic kidney disease of unknown etiology (CKDu). Those who have a knowledge on soil science reiterate the fact that at rates of fertiliser applied in Sri Lanka, there is only a very low risk on health. For example, a final report of a government-funded research project on CKDu, led by Senior Professor Rohana Chandrajith of the University of Peradeniya can be considered a case in point. According to that report, causes for CKDu have been narrowed down to three reasons; namely fluoride content and magnesium content in drinking water, and low water intake by farmers. None of these causes are related to agrochemicals used in those areas. Even for other health issues highlighted by 100% organic supporters, a cause-effect relationship has not been established by scientific investigations.
Deficit of organic fertiliser
If the governments strive for 100% organic agriculture, they first wanted to produce the required quantities of organic fertilisers within the country and within 3-4 months before the next cropping season (i.e. this Maha season) starts. They failed to achieve this target and farmers are demanding fertilisers. Then without listening to the outcry of scientists not to import organic fertilisers, as it is a threat to our bio-diversity, plant and animal health, the government decided to import an “organic nitrogen fertiliser” from a Chinese Company. At least two sets of randomly drawn samples from these organic fertiliser stocks were found to be contaminated by pathogens and micro-organisms. Later, the government announced that they will not allow this seaweed and manure-based nitrogen fertiliser to enter the country. The Chinese government then issued a press release saying that our test reports were not accurate. Despite all this the ship carrying the fertiliser lot is still sailing, and we will have to wait and see how the Sri Lankan government will handle the pressure from the Chinese government to accept that fertiliser lot.
Produce from agricultural lands is the lifeline and only income source of the farming community. They are in dire need of fertilisers. Some farmer societies have even decided not to accept water from the irrigation tanks until there is an assurance from the government on fertilisers. If fertilisers are not provided on time to farmers, this could lead to another crisis; management of water in irrigation tanks.
Nano-Urea: An illusion
The government has decided to purchase an alternative fertiliser called “Nano-N” from India. Part of this fertiliser was airlifted as the cultivation has already started in some parts of the country and received on 20t October. Again, Secretary to the Ministry of Agriculture was on record saying it was a highly efficient “organic” liquid nitrogen fertilser. One hectare of paddy land requires only 2.5 liters of this Nano-N. This time someone has given the wrong advice to the Ministry of Agriculture and the government.
The patent right for “Nano-N” fertiliser is owned by Indian Farmer Fertiliser Corporations Ltd. (IFFCO) and is produced in a factory owned by IFFCO in Gujarat. They invented this technology in 2019 and released for commercial purposes in June 2021. This suggests that even in India there is a limited experience on the use of this fertiliser. To the best of my knowledge there is no experimental evidence on the use of this product under Sri Lankan conditions. There are some important aspects of this Nano-N that farmers and general public must be aware.
If this is a “organic” fertiliser, as the Secretary to the Ministry of Agriculture states, this must be imported into the country according to the conditions set forth in the Plant Protection Act following proper protocols to avoid another fiasco like the Chinese organic fertiliser issue. But what authorities is hiding from the public is that this “Nano-N” is actually a synthetic fertiliser that cannot be used in organic agriculture. According to the web site of IFFCO, this product is actually called “Nano-Urea” and hence cannot be organic.
This “Nano-Urea” contains only 4% nitrogen as against 46% nitrogen in urea granules. If only 2.5 litres of “Nano-Urea” is applied per hectare, rice plants will receive only 100 grams of nitrogen. This is assuming 100% efficiency which we will never achieve in nature. The most important point here is that to produce five tons of paddy harvest from one hectare, plant needs 105 kg of nitrogen of which 50 kilos of nitrogen are in grains. Therefore, anybody can calculate how many liters of “Nano-Urea” is required to produce the expected yield. That is 1,250 liters of “Nano-Urea” per hectare to provide at least the nitrogen that is removed from paddylands with harvest (i.e. 50kg N). Because of this, the limited available Indian research indicates that “Nano-Urea” cannot be applied as the only source of nitrogen but must be used together with at least 50% of nitrogen from other organic and chemical sources. By giving farmers only 2.5 liters of “Nano-Urea”, farmers will definitely reduce productivity. Our research evidence suggests that paddy yield loss due to lack of nitrogen fertilisers could be around 16-60% depending on the site characteristics. Therefore, “Nano-Urea” will endanger our national security as we will have to depend on other countries for our staple food.
According to the IFFCO website, 500ml bottle of “Nano-Urea” costs about Rs.640 (Indian Rs.240). Even if airfreight and other costs are ignored, the cost of one kilo of nitrogen in “Nano-Urea” is Rs.31,000, where as one kilo of nitrogen in granular urea is only Rs.130. No wonder why the government has decided to provide only 2.5 liters of “Nano-Urea” per hectare. What this writer cannot understand is that a much cheaper synthetic fertiliser like urea has been banned in their quest for 100% organic agriculture and then import another type of synthetic urea fertiliser at a price of 240 times higher. The government has ordered 3.1million liters of “Nano-Urea” from IFFCO at a cost of Rs.4,000,000,000 (Rs. four billion according to the figures given above). If farmers need to obtain their expected yields, the government has to provide farmers with additional sources of nitrogen. But the country has not produced enough organic or bio fertilisers to provide at least one-third of nitrogen required by different crop sectors.
The government is creating an illusion that the “Nano-Urea” is a wonder product that can replace 50kg of urea bag with just half a liter of this liquid nano-fertiliser. Of course, they are relying on the information provided by the IFFCO. According to IFFCO, because urea is in “Nano” size particles, plants can absorb nitrogen from this product easily and utilize efficiently. What they probably not aware or hide from the public is that urea is 100% water soluble and they dissolve almost instantaneously disintegrating urea granule into urea molecules. The size of a urea molecule is much smaller (approximately 0.3 to 0.5 Angstrom in different dimensions) than that of a “nano-urea” particle (200 to 500 Angtrom). If the size determines the absorption efficiency, then dissolved urea must get absorbed faster. Therefore, the question is why “Nano-Urea” needs to be produced in the first place. According to the limited literature on “Nano-Urea” this writer reviewed, the IFFCO conducted field experiments do not have a liquid urea only treatment to compare with “Nano-Urea” treatment. This raises some concerns, at least in this writer’s opinion, on the significance of this wonder product.
Nano products are new to the environment and not enough research has been conducted on the long-term effects of nano particles on human health and environment. Therefore, in many organic agriculture certification systems nano fertilisers are not allowed. Therefore, before such new products are introduced, adequate research must be conducted in a given environment to ensure environmental sustainability that is expected from organic agricultural systems.
Finally, if the government is not taking evidence-based advices from their “advisors”, we can only wait and see what will become of our food security and hence the national security vis-à-vis the interests of world powers.

‘The devil is in the details’ in West Asian peace
It is obviously too early for an outpouring of joy over the seeming cessation of hostilities between the main antagonists in West Asia. While the prospect of there being a measure of calm in the region is being welcomed by considerable sections of the international community, what is ‘on the table’ currently is only a Memorandum of Understanding between the US and Iran to give peace a chance. The hard part in the peace effort remains to be achieved.
In the Middle East of today we have one of the most complex conflicts to break out in modern international politics and the observer would be naive in the extreme to expect a facile and early closure to the tangle. Yet, for the sake of the world’s publics who have been hurting badly in the prolonged hostilities one could only hope that the US-Iran MoU that is expected to be signed by the sides on Friday would lead eventually to a substantive peace. The world’s thanks are due to Pakistan in this connection for its sustained support in the peace drive.
While the sides have agreed to a ceasing of hostilities in the most general terms and have reached accord on the facilitation of uninterrupted oil and gas supplies to the rest of the world, for instance, the ‘devil will prove to be in the details’ in an envisaged comprehensive peace settlement. It is these details that would make or break peace if the negotiations go on in earnest.
Nevertheless, the details would need to be worked out consensually in a spirit of compromise with an eye to the greater good of the world community. Realpolitik or a narrow focus on solely the national interest among the protagonists, for example, would need to give way to a measure of humanity that would encompass within it a consideration of the overall well being of the world. In other words, it is statesmanship that would crucially matter.
The next few weeks would establish whether humanists are ‘asking for far too much’ when they broach the questions at issue in these terms. Yet it is essentially self interest and national security considerations of the first importance that drove the conflict from even prior to February this year and these questions would need to be taken up and resolved to the satisfaction of the US and Iran in the main if some headway is to be made towards a durable settlement.
The nuclear issue would prove to be the proverbial Gordian Knot. From a realistic viewpoint, Iran could not be expected to be without a potential nuclear deterrent in the face of perceived nuclear threats emanating for it from the West and Israel. In the short term, Iran would need to possess this deterrent to a measure, within a mutually agreed international legal framework maybe, until wide agreement is reached on the nuclear tangle. Specifically, Iran’s immediate threat perceptions with regard to her nuclear-powered rivals would need to be defused during initial negotiations.
Ideally it is a world free of nuclear weapons that must be aimed at but since this goal cannot be achieved in the near or medium terms, unfolding negotiations would need to ensure Iran’s absolute security in a world of powers that continue to swear by the nuclear deterrent, if it is to give up the suspected latter capability.
However, it is to the degree to which the present nuclear powers divest themselves of this capability that Iran could be put at ease on this score. Accordingly, it is nothing short of a complete elimination of nuclear weapons from the world that could dissuade keenly security conscious states from developing nuclear weapons of their own with a mass destruction capability.
This is the number one dilemma the international community needs to grapple with going forward and it is to the extent to which it resolves it that a nuclear weapons free world could be envisaged. No doubt, an uphill challenge.
Compelling Israel to support the present negotiatory process constitutes another grueling challenge for the US. Currently the Iranian position essentially is that a Middle East peace is inseparable from a normalization of the security situation in Lebanon. That is, the present Israeli attacks on the Hezbollah presence in Lebanon must cease if a comprehensive peace is to be realized in West Asia.
However, Israel is showing no signs of drawing back from its attacks on Hezbollah strongholds in Lebanon since the security of the Israeli state is being seen as threatened by the militant group. Co-opting Israel into the negotiatory effort therefore would turn out to be a matter of paramount concern for the US.
Moreover, elements in the rightist administration in Israel are seeing the current peace efforts as a ‘sell out’ to the enemies of Israel. They would have none of it. It is left to be seen how the US would be managing these virtual storm centres in the diplomatic process that could very well bring down the overall purported peace drive.
A recent pronouncement by US Vice President J.D. Vance points to yet another problem area in the US’ current peace overtures. He said that, ‘Regional peace and stability includes stopping the funding of terrorist organizations.’ He was obviously referring to the support extended by Iran to Hezbollah when he mentioned ‘terrorist organizations’ but he has given fresh life to the age-old conundrum of ‘Who is a terrorist?’ by these words.
To the Netanyahu government the Hezbollah and other militant organizations fighting Israel are ‘terrorists’ but from the viewpoint of the Iranian regime they are ‘freedom fighters’. This seemingly insurmountable definitional issue would not only stubbornly bedevil the peace effort but could even figure in bringing about its collapse, unless judiciously handled.
Thus, it’s the thorny details that need to be watched to keep the West Asian peace process afloat, once it gets going in earnest. There is no doubt that US President Trump would be receiving a considerable amount of support from the G7 in this historic peace undertaking and his personal appeals to the grouping currently meeting in France for continuous support are likely to elicit a positive response from it.
Likewise, Trump would need to appeal to also the BRICS countries if almost total global support is to be garnered for the peace drive in West Asia. BRICS’ solidarity with the US and the West is likely to carry considerable weight with Iran and other Eastern actors who are key to a sustained peace drive in the Middle East.

Sri Lanka’s elephant paradox: Govt. counts tourism dollars while playing a dangerous numbers game: Expert
At a time when Sri Lanka is enjoying a resurgence in wildlife tourism, with elephants remaining the undisputed stars of the country’s national parks and one of its most marketable natural assets, elephant conservationist Supun Lahiru Prakash has sounded a stark warning: the nation is in danger of losing the very species that helps attract millions of tourism dollars while sustaining some of the island’s most important ecosystems.
Supun says repeated claims by authorities that Sri Lanka’s elephant population is increasing, despite the absence of a final survey report and amid continuing elephant deaths, risk creating a misleading narrative that could undermine conservation efforts and encourage retaliation against elephants.
According to Supun, the issue is not merely about numbers. It is about political priorities, scientific credibility and the future of one of Sri Lanka’s most iconic species.
“Repeatedly claiming that the elephant population is increasing appears to be an attempt to hide the Government’s inability to manage the rising annual elephant death rate and the complications of human-elephant conflict,” Supun said.
For decades, the Sri Lankan elephant has been a symbol of the country’s rich natural heritage. It is the centrepiece of wildlife tourism, drawing visitors from across the globe to national parks such as Yala, Udawalawe, Minneriya, Kaudulla and Wilpattu. International wildlife documentaries, tourism campaigns and social media promotions frequently place elephants at the heart of Sri Lanka’s nature tourism brand.
Yet, according to Supun, the country’s conservation policies do not reflect the value of the species.
“On one hand, the Government is enjoying increasing tourism revenue, and elephants remain one of Sri Lanka’s most important wildlife attractions. On the other hand, narratives are being promoted that could encourage retaliation against the very species that contributes significantly to the country’s tourism industry,” Supun said.
According to the First Countrywide National Survey of Elephants conducted in 2011, Sri Lanka had 5,879 elephants. However, official statistics show that 4,167 elephants died between 2012 and 2024.
Supun stressed that these figures represent only the deaths officially recorded by the Department of Wildlife Conservation.
“In a context where more than 70 percent of the country’s elephant population reported in 2011 has died within 13 years, it is difficult to accept claims that the population has increased,” Supun said.
The conservationist pointed out that elephants have the longest gestation period among land mammals and that scientific studies have reported increasing interbirth intervals among female elephants together with high calf mortality.
“When such biological realities are taken into consideration, claims of a dramatic increase in elephant numbers become difficult to understand,” Supun said.
Supun believes that repeated references to increasing elephant populations risk fuelling public hostility towards elephants, particularly among farming communities already affected by crop raids and property damage.
“Such claims can create the impression that elephant populations are exploding and thereby promote retaliation against elephants as well,” Supun said.
According to Supun, Sri Lanka’s elephant crisis cannot be understood solely through population estimates. The real issue lies in the country’s failure to address human-elephant conflict through long-term, science-based solutions.
Sri Lanka continues to record among the highest levels of human-elephant conflict in the world. Every year, hundreds of elephants and dozens of people lose their lives as competition for land and resources intensifies.
Despite the scale of the crisis, Supun says authorities continue to rely on strategies that have repeatedly failed.

Lahiru Prakash
These include driving elephants into protected areas, strengthening electric fences to confine them there and allocating additional manpower to maintain fencing systems.
Supun was also critical of several proposals that emerged from district-level discussions on conflict mitigation, including the sowing of paddy and corn using Air Force drones and the planting of fruit orchards within protected areas.
“Such proposals fail to address the real ecological and social dimensions of the conflict,” Supun said.
While welcoming reports that the Government intends appointing a national-level mechanism to tackle human-elephant conflict, Supun said the challenge required intervention at the highest level of government.
“Given the gravity, complexity and geographical spread of human-elephant conflict, appointing any committee other than a Presidential Task Force is not useful,” Supun said.
He argued that a Presidential Task Force chaired by either the President or the Secretary to the President would be better positioned to overcome the bureaucratic delays and institutional fragmentation that have hindered previous efforts.
Supun also stressed the urgent need to restore and protect elephant corridors and home ranges that allow elephants to move safely across landscapes.
He cited the Koholankala elephant corridor in Hambantota as one example where removing obstacles could help reduce conflict while improving habitat connectivity.
At the same time, Supun questioned policies that permit the allocation of forest lands in areas identified by environmental assessments as crucial elephant ranges and movement corridors.
“The opening of elephant corridors and the protection of elephant home ranges must be carried out scientifically and consistently if they are to succeed,” Supun said.
Beyond tourism, Supun emphasised the ecological importance of elephants.
“Elephants are ecosystem engineers. Through their feeding habits and movements, they help maintain habitats that support numerous other species. In many ways, they create safer and healthier environments for wildlife,” Supun said.
According to Supun, protecting elephants means protecting entire ecosystems and the biodiversity upon which Sri Lanka’s wildlife tourism industry depends.
“By protecting elephants, we are also protecting the biodiversity that makes Sri Lanka one of the world’s premier wildlife tourism destinations,” Supun said.
As Sri Lanka seeks to expand tourism earnings and strengthen its reputation as a wildlife destination, Supun believes the country faces a defining choice: continue with policies that have failed to stem elephant deaths and human-elephant conflict, or embrace a science-based conservation strategy that safeguards both people and wildlife.
Without a fundamental shift in policy and political will, Supun warned, Sri Lanka risks losing not only one of its most iconic species but also the ecological and economic benefits that elephants continue to provide.
“The suffering of both farmers and elephants will only intensify unless meaningful action replaces rhetoric,” Supun said.
