Banning fertilizer imports
By Dr. C. S. Weeraratna
csweera@sltnet.lk
According to recent news, import of fertilizers is going to be banned. The President at a recent meeting highlighted the importance of shifting towards organic fertilizers by gradually decreasing the usage of chemical/inorganic fertilizers. According to the National Fertilizer Secretariat, in 2020, we imported around 580,000 MT of inorganic fertilizers costing Rs. 36 billion. Of this amount around 50% is used for paddy and the balance for planation crops and field crops.
In 2019 around Rs 300 billion worth of food has been imported. Among the imported food are green gram, red onions, big onions, maize, etc., which can be locally produced. If we are to reduce our expenditure on food imports it is essential that the local food production is increased. For effectively addressing this issue several inputs are important. Among these are good quality seeds/planting material, and use of appropriate technology. In this regard judicious use of fertilizers is important. .
There are two types of fertilizers. Inorganic fertilizers (IF) such as ammonium sulphate, urea, Triple Super Phosphate and muriate of potash which supply nutrients nitrogen, phosphorus and potassium respectively and are called macronutrients. Plants need them to grow and produce. Several research studies conducted in Sri Lanka and elsewhere indicate that the application of IF tends to increase growth and yields of crops.
Organic fertilizers such as compost, animal residues contain very small amounts of macronutrients, but some essential plant nutrients such as iron, manganese, copper, etc, called micronutrients which are not present in inorganic fertilizers.
Effects of banning fertilizers
Except for Eppawela Apatite Inorganic fertilizers are not manufactured locally. If the import of IF is going to be banned, and organic fertilizers (OF) used instead, it is likely that yields of all crops will decrease. As indicated research studies conducted in Sri Lanka and elsewhere indicate that application of IF tend to increase growth and yields of crops. Currently, the average paddy production in Sri Lanka is about 4 t/ha and this is likely to be reduced if inorganic fertilizers are not applied. The same will apply to other crops including tea as well which has a positive effect on the economy of the country. Already paddy farmers in some areas are complaining that basal fertilizers are not available for the Yala crop. If IFs are not available, llocal crop production will decrease causing food imports such as rice, pulses, etc.,to increase and reducing exports of plantation crops exacerbating the present economic and social problems. Thus, the final effect of banning fertilizer imports will be on the economy of the country which is already in a dire status.
If the imports of these IFs is going to be banned it is essential that alternatives are available as plants need nutrients to grow and produce. Organic fertilizers such as compost which is considered to be an alternative does not supply these macronutrients in adequate amounts unless large quantities of OFs are used. For example, to supply nitrogen in 100 kg of urea (urea has 46% N) a farmer has to apply around 2 tons of compost (only 2% N). OF are not alternatives to IF but supplementary.
Based on Central Bank reports, in 2019, expenditure on food and beverages is around Rs 300 Billion. The expenditure in 2021 on food imports is likely to be even more due to the depreciation of SL rupee. Banning IF will reduce our expenditure on imports by app. Rs. 36 billion but at the same time it will reduce local food production and increase our annual expenditure on food imports which at present is around Rs. 300 billion. It will also have an adverse impact on food security.
Alternatives:
If import of Inorganic fertilizers is to be banned, it is necessary to resort to alternative methods of supplying nutrients required by plants. Biological nitrogen fixation (BNF) if used will tend to reduce our N fertilizer imports to some extent. BNF is a process carried out by various groups of microorganisms. Studies on BNF have been conducted in Sri Lanka for almost three decades by scientists such as Prof. S. A. Kulasuriya. Results of these studies show that nitrogen-fixation by organisms such as azolla, blue-green algae and rhizobia can be used to supplement inorganic nitrogen fertilizers. BNF is used profitably by farmers in many other countries such as India, China, Vietnam etc. It is necessary to implement an integrated plan to promote the use of Biological Nitrogen Fixation in crop production.
Organic fertilizers can be used to supplement IF as OF supply micronutrients which are not present in inorganic fertilizers. OF production units, in each village, would maximise utilization of resources and provide employment on a large scale. Any type of organic material is not suitable to be applied to crops. For example, those made from city wastes may contain toxic elements such as heavy metals. OF can be used in intensive agricultural systems but in crops such as paddy, and planation crops which are cultivated extensively, compost is not effective enough to supply plant nutrients required by plants.
Application of inorganic fertilizers with organic fertilizers would give higher yields. Hence, it is necessary to implement a concerted plan to promote application of organic fertilizers. It is extremely important that the advantages and disadvantages of banning inorganic fertilizers need to be carefully considered by relevant authorities before deciding to ban these fertilizers.
Issues associated with IF
It has been reported that some farmers, apply phosphatic and potasic fertilizers more than what is required. Hence it would be desirable if the amounts of fertilizers to be applied are based on soil tests. There is a need for improving on-farm nutrient management using an integrated nutrient management approach, combining inorganic and organic fertilizers. In most of the annual cropping systems managed with IF, the application of organic fertilizer as a supplement is essential. Insufficient organic matter levels in soils would lead to leaching of the inorganic fertilizers added to soil. Around 40% of N in urea applied to soil tends to get lost due to volatilization and leaching. The total benefits of inorganic fertilizers can be realized only by having adequate organic matter levels in the soils by applying OF.
Although highly debated, some are of the opinion that fertilizers is one of the cause of increased incidents of chronic kidney disease with unknown aetiology (CKDU) in the country. An international expert consultation on CKDu was held in Colombo in April 2016. It was organized by the Presidential Task Force for Prevention of Chronic Kidney Disease and the Sri Lanka country office of the World Health Organization (WHO). The consultation concluded that there was no conclusive evidence to indicate that there was any relationship between CKDU and fertilizers.

Nilanthi Jayasinghe – An Appreciation
It was with shock that I realized that the article in the Sunday Island of April 5 about the winsome graduate gazing serenely at her surroundings was, in fact, an obituary about Nilanthi Jayasinghe, a former colleague who I had held in high esteem. I had lost touch with Nilanthi since my retirement and this news that she had passed away, saddened me deeply
I knew and had worked with Nilanthi – Mrs Jayasinghe as we used to call her – at the Open University of Sri Lanka in the 1990s. As Director, Operations, she was a figure that we as heads of academic departments, relied on; a central bastion of the complex structure that underpinned academic activities at Sri Lanka’s major distance education provider. Few people realize what it takes to provide distance education in an environment not geared to this form of teaching/learning – the volume of Information that has to be created, printed and delivered; the variety of timetables that have to be scheduled; the massive amount of continuous assessment assignments and tests that have to be prepared and sent out; the organization of a multitude of face-to face teaching sessions; the complex scheduling of examinations and tests – all this needed to be attended to for a student population of more than 20,000 and for 23 centres of study dotted across Sri Lanka.
It was an unenviable task but Nilanthi Jayasinghe with her flair for organization, handled it all with aplomb and a deep sense of commitment. If there were delays and inconclusive action on our part, she never reprimanded but would work with us to sort things out. Her work as Director, Operations brought her into contact with staff across the spectrum-from the Vice-Chancellor to the apprentice in the Open University’s Printing Press. Nilanthi treated everyone with dignity and as a result, was respected by all at the university. She was sensitive, kind-hearted, a good friend who would readily share problems and help to solve them. The year NIlanthi retired, I was out of the island. When I came back to the Open University, I felt bereft without the steadfast support of her stalwart presence .
The article in the ‘Sunday Island’ describes her life after retirement, looking after family members and enjoying the presence of a granddaughter.
After a lifetime of commitment to others, Nilanthi Jayasinghe truly deserved this happiness.
May she be blessed with peace.

James Selvanathan Mather
James Mather (Selvan to all of us) who passed away recently at the age of 95 was one of the leading Chartered Accountants in the country. He was the senior partner of Ernst and Young for long years, and the mentor for a generation of chartered accountants. He was confidante and adviser to many of the leading businessmen of his time. His career spanned over six decades. A man who never sought the limelight, he was very influential in Ceylon/Sri Lanka’s business world.
Selvan Mather was born in 1930 to a well-known Christian family in Jaffna. His father, Rev. James Mather was Head of the Methodist Church in Ceylon. Selvan was educated at Trinity College Kandy, and he had a life-long connection with the school. He entered the University of Ceylon in the late 1940s, at a time when Ivor Jennings was Vice-Chancellor.
He read economics and passed out with an honours degree. For short periods he was in the Department of Income Tax and with the newly established Central Bank of Ceylon. The Central Bank facilitated him to go to England to qualify as a chartered accountant. His two referees, when seeking admission to an accountancy firm in the U.K. were M.D.H. Jayawardena, then Minister of Finance and the Auditor General of Ceylon, L.A. Weerasinghe. Being a chartered accountant was a rare event those days.
On his return from England, his career was with Ernst and Young where he became senior partner. He was close advisor and confidante to many of the leading businessmen. He was admitted to its Hall of Fame by the Institute of Chartered Accountants.
To strike a personal note, I got to know him 50 years ago when he applied for a fellowship given by the Asian Productivity Organisation (APO) in Tokyo. I was in the Ministry of Planning and Economic Affairs at the time, and the Ministry was handling APO affairs in Colombo. He told me later that he enjoyed his time in Tokyo. From that time, we kept up a friendship with him and Nelun, which lasted 50 years.
My wife, Rukmal, and I lived in Windsor England, for about 25 years. During that time, Nelun and Selvan were regular visitors to England. I remember taking him for long walks in Windsor Great Park, and on the grounds of Eton College which were nearby. We went on long car tours in England covering the Cotswolds, the Peak districts and the Potteries. I remember celebrating Selvan’s 70th birthday in London at a Greek restaurant, along with his great friends, Nihal and Doreen Vitarana. Memories remain, although Selvan is no more.
In the last decades of his life we saw Nelun and him often. A few of us, Manik de Silva, Nihal and Srima Seneviratne and a few others met regulsrly for lunch. We will all miss Selvan who was mine of his life and times very much.
Selvan leaves his wife Nelun and three children and their husbands – Rohan, Shyamala and Indi, and Rehana and Akram. It was a close-knit family and they will miss him.

War with Iran and unravelling of the global order – II
Broader Strategic Consequences
One of the most significant strategic consequences of the war is the accelerated erosion of U.S. political and moral hegemony. This is not a sudden phenomenon precipitated solely by the present conflict; rather, the war has served to illuminate an already evolving global reality—that the era of uncontested U.S. dominance is in decline. The resurgence of Donald Trump and the reassertion of his “America First” doctrine reflect deep-seated domestic economic and political challenges within the United States. These internal pressures have, in turn, shaped a more unilateral and inward-looking foreign policy posture, further constraining Washington’s capacity to exercise global leadership.
Moreover, the conduct of the war has significantly undermined the political and moral authority of the United States. Perceived violations of international humanitarian law, coupled with the selective application of international norms, have weakened the credibility of U.S. advocacy for a “rules-based international order.” Such inconsistencies have reinforced perceptions of double standards, particularly among states in the Global South. Skepticism toward Western normative leadership is expected to deepen, contributing to the gradual fragmentation of the international system. In this broader context, the ongoing crisis can be seen as symptomatic of a more fundamental transformation: the progressive waning of a global order historically anchored in U.S. hegemony and the emergence of a more contested and pluralistic international landscape.
The regional implications of the crisis are likely to be profound, particularly given the centrality of the Persian Gulf to the global political economy. As a critical hub of energy production and maritime trade, instability in this region carries systemic consequences that extend far beyond its immediate geography. Whatever may be the outcome, whether through the decisive weakening of Iran or the inability of external powers to dismantle its leadership and strategic capabilities, the post-conflict regional order will differ markedly from its pre-war configuration. In this evolving context, traditional power hierarchies, alliance structures, and deterrence dynamics are likely to undergo significant recalibration.
A key lesson underscored by the war is the deep interconnectivity of the contemporary global economic order. In an era of highly integrated production networks and supply chains, disruptions in a single strategic node can generate cascading effects across the global system. As such, regional conflicts increasingly assume global significance. The structural realities of globalisation make it difficult to contain economic and strategic shocks within regional boundaries, as impacts rapidly transmit through trade, energy, and financial networks. In this context, peace and stability are no longer purely regional concerns but global public goods, essential to the functioning and resilience of the international system
The conflict highlights the emergence of a new paradigm of warfare shaped by the integration of artificial intelligence, cyber capabilities, and unmanned systems. The extensive use of unmanned combat aerial vehicles (UCAVs)—a trend previously demonstrated in the Russia–Ukraine War—has been further validated in this theatre. However, unlike the Ukraine conflict, where Western powers have provided sustained military, technological, and financial backing, the present confrontation reflects a more direct asymmetry between a dominant global hegemon and a Global South state. Iran’s deployment of drone swarms and AI-enabled targeting systems illustrates that key elements of Fourth Industrial Revolution (4IR) warfare are no longer confined to technologically advanced Western states. These capabilities are increasingly accessible to Global South actors, lowering barriers to entry and significantly enhancing their capacity to wage effective asymmetric warfare. In this evolving context, technological diffusion is reshaping the strategic landscape, challenging traditional military hierarchies and altering the balance between conventional superiority and innovative, cost-effective combat strategies.
The war further exposed and deepened the weakening of global governance institutions, particularly the United Nations. Many of these institutions were established in 1945, reflecting the balance of power and geopolitical realities of the immediate post-Second World War era. However, the profound transformations in the international system since then have rendered aspects of this institutional architecture increasingly outdated and less effective.
The war has underscored the urgent need for comprehensive international governance reforms to ensure that international institutions remain credible, representative, and capable of addressing contemporary security challenges. The perceived ineffectiveness of UN human rights mechanisms in responding to violations of international humanitarian law—particularly in contexts such as the West Bank and the Gaza Strip, and more recently in Iran—has amplified calls for institutional renewal or the development of alternative frameworks for maintaining international peace and security. Moreover, the selective enforcement of international law and the persistent paralysis in conflict resolution mechanisms risk accelerating the fragmentation of global norms. If sustained, this trajectory would signal not merely the weakening but the possible demise of the so-called liberal international order, accelerating the erosion of both the legitimacy and the effective authority of existing multilateral institutions, and deepening the crisis of global governance.
Historically, major wars have often served as harbingers of new eras in international politics, marking painful yet decisive transitions from one order to another. Periods of systemic decline are typically accompanied by instability, uncertainty, and profound disruption; yet, it is through such crises that the contours of an emerging order begin to take shape. The present conflict appears to reflect such a moment of transition, where the strains within the existing global system are becoming increasingly visible.
Notably, key European powers are exhibiting a gradual shift away from exclusive reliance on the U.S. security umbrella, seeking instead a more autonomous and assertive role in global affairs. At the same time, the war is likely to create strategic space for China to expand its influence. As the United States becomes more deeply entangled militarily and politically, China may consolidate its position as a stabilising economic actor and an alternative strategic partner. This could be reflected in intensified energy diplomacy, expanded infrastructure investments, and a more proactive role in regional conflict management, advancing Beijing’s long-term objective of reshaping global governance structures.
However, this transition does not imply a simple replacement of Pax Americana with Pax Sinica. Rather, the emerging global order is likely to be more diffuse, pluralistic, and multilateral in character. In this sense, the ongoing transformation aligns with broader narratives of an “Asian Century,” in which power is redistributed across multiple centers rather than concentrated in a single hegemon. The war, therefore, may ultimately be understood not merely as a geopolitical crisis, but as a defining inflection point in the reconfiguration of the global order.
Conclusion: A New Era on the Horizon
History shows that major wars often signal the birth of new eras—painful, disruptive, yet transformative. The present conflict is no exception. It has exposed the vulnerabilities of the existing world order, challenged U.S. dominance, and revealed the limits of established global governance.
European powers are beginning to chart a more independent course, reducing reliance on the U.S. security umbrella, while China is poised to expand its influence as an economic stabiliser and strategic partner. Through energy diplomacy, infrastructure investments, and active engagement in regional conflicts, Beijing is quietly shaping the contours of a more multipolar world. Yet this is not the rise of Pax Sinica replacing Pax Americana. The emerging order is likely to be multilateral, fluid, and competitive—a world in which multiple powers, old and new, share the stage. The war, in all its turbulence, may therefore mark the dawn of a genuinely new global era, one where uncertainty coexists with opportunity, and where the next chapter of international politics is being written before our eyes.
