Fertilizer supply shortages are a chronic problem in Nepal, where thousands of farmers are often unable to access the required quantities on time. This is particularly common during the cultivation of rice — the major staple food crop for the country.

Some of the critical challenges to meeting fertilizer demand include limitations to import mechanisms and budget allocation for fertilizer subsidies by the Government of Nepal. Additionally, the successive COVID-19-induced lockdowns and Russia-Ukraine war have further deepened the crisis in the past two years by significantly delaying imports and increasing fertilizer prices. This continuous gap in supply has compelled farmers to buy fertilizers from the country’s unofficial or “gray” markets.

To address these shortcomings, researchers on the Nepal Seed and Fertilizer (NSAF) project, implemented by the International Maize and Wheat Improvement Center (CIMMYT), have been supporting the Fertilizer Association of Nepal (FAN) and the Ministry of Agriculture and Livestock Development (MOALD) to resolve policy issues that will enhance fertilizer distribution efficiency.

On 23 September 2022, the NSAF project team joined representatives from the International Fertilizer Development Center (IFDC) and FAN to organize a policy dialogue around improving the country’s fertilizer supply system. Held in Kathmandu, the event brought together concerned public and private sector stakeholders to discuss existing challenges and propose different policy alternatives that ensure the timely availability of fertilizers in the required quantities.

Representatives from FAN presented the key issues and challenges in the sector while NSAF project coordinator Dyutiman Choudhary presented the findings of different fertilizer policy studies conducted jointly with local partners. The results showed that involving the private sector in distribution improved farmers’ access to fertilizers compared to distribution carried out solely by cooperatives. The study also indicated a potential to reduce fertilizer subsidies and increase import volume to help meet demand.

Improving national supply systems

The event featured a panel discussion, where participants shared their experiences and outlined the issues faced by private sector importers, logistic service providers and retailers, and policymakers from federal and provincial governments while engaging in their respective functions. The panel members also suggested a number of different ways to improve national fertilizer supply systems, such as:

  1. Restructuring fertilizer subsidy programs, i.e. reducing the current subsidy by 20-30% (a recommendation from the NSAF assessment) and using budget savings to increase imports and allocate subsidies based on fertilizer demand.
  2. Making a procurement process timeline to ensure timely fertilizer supply for three major crops — rice, wheat, and maize — and importing about 30% of the total fertilizer through Government-to-Government (G2G) agreement.
  3. Implementing a crisis management strategy by maintaining buffer stocks (20% of the demand).
  4. Ensuring a level playing field for the private sector in the import and distribution of the fertilizers.

The dialogue concluded with mutual agreement by stakeholders from the public and private sectors to improve local fertilizer distribution through private sector engagement. They agreed to revise some clauses specified in the Nepal Fertilizer Distribution Directive 2020 related to profit margins, volumes, classification of fertilizer distributors and selling fertilizers. Govinda Prasad Sharma, secretary of MOALD, informed attendees that the ministry has already started planning fertilizer procurement based on actual demand and gave assurances about G2G agreements with neighboring countries such as India to bring in fertilizers for distribution during times of peak demand. Sharma also agreed to continue supporting the private sector in capacity building to import fertilizers and to revise subsidies to make more fertilizers available.

“It is our great pleasure to see all fertilizer-related stakeholders in a common platform, which is critical to bring out key issues and cooperation between the public and private sector,” said Lynn Schneider, deputy director of the Economic Growth Office at USAID Nepal. Schneider also emphasized the importance of generating efficiency in estimating fertilizer demand and supply and fertilizer types by using Nepal’s digital soil map, working in close coordination with provincial and local governments, and increasing the role of the private sector to ensure fertilizer supply to meet crop requirements in the peak season.

The Nepal Seed and Fertilizer project is supported by the United States Agency for International Development (USAID) and is a flagship project in Nepal. It aims to build competitive and synergistic seed and fertilizer systems for inclusive and sustainable growth in agricultural productivity, business development and income generation in Nepal.

Nepal Government endorses new site-specific fertilizer recommendations for rice

After four decades, new site-specific fertilizer recommendations for rice have been introduced in Nepal that will help farmers increase the crop’s productivity by 10-30%, compared to their current practices.

The Ministry of Agriculture and Livestock Development (MoALD) endorsed the new fertilizer recommendations for rice crop at a consultative workshop in July 2022 held in Kathmandu. Developed by the International Maize and Wheat Improvement Center (CIMMYT), in close collaboration with the Nepal Agriculture Research Council’s (NARC) National Soil Science Research Center (NSSRC) and International Fertilizer Development Center (IFDC), the new regime replaces the existing blanket approach of recommendations to help increase crop yields and fertilizer use efficiency.

The blanket approach assumed the whole country as one domain despite the heterogeneity in soils, other biophysical conditions and agronomic management practices, including crop varieties. As a result, fertilizers were under-utilized in low fertile soils or overused in farms with high soil fertility status, thereby farmers were not able to obtain the achievable yield.

Unlike the generic recommendations, the site-specific fertilizer management will help farmers to determine the crop’s fertilizer requirements based on soil fertility status of a particular farm, attainable yield target of the selected crop variety, crop’s yield response to fertilizers and agronomic management practices, such as irrigation, cropping systems etc. In other words, this new regime allows farmers to produce more with less fertilizers through a balanced application of fertilizers based on available soil properties.

Old is not always gold

Generally, soil fertility status changes every 3-5 years when there is continuous nutrient removal from soils due to an intensive cropping system with the adoption of high nutrient demanding improved and hybrid varieties. Thus, soil fertility management recommendations should be updated periodically but the existing recommendations were not updated since 1976.

Realizing the limitations, CIMMYT through the Nepal Seed and Fertilizer (NSAF) project, supported by USAID, worked with NSSRC and IFDC to formulate fertilizer recommendations for major cereal crops and vegetables for specific domains of the country.

Under NSSRC’s leadership, a ‘Fertilizer Recommendation Committee’ comprising of a dedicated team of soil scientists within NSSRC and NSAF experts was formed to develop site-specific fertilizer recommendations using the Soil-SMART framework for delivering balanced fertilizers to farmers. Based on soil fertility status, agro-climate, irrigation regimes and geography, the country was divided into six soil fertility domains — four in the Terai region (Eastern, Central, Western and Far-western), one in inner Terai and one in the hills. Under each domain, recommendations were based on the attainable yield, crop variety, and irrigation regime.

This approach was first tested for rice crop.

Formulating new recommendations for rice

Three fundamental steps were used to develop site-specific fertilizer recommendations, which included: i) selection of yield goal, ii) estimation of crop nutrient requirement, and iii) estimation of indigenous nutrient supplies. To collect this information, NSAF and the committee designed field trials on nutrient omission and nutrient rates to determine the yield limiting nutrients and their optimum rate, respectively. Data from fertilizer trials conducted by different research institutes and universities, including trials from the project sites were collected and analyzed by the team to see the crop’s yield response to fertilizers. A modeling approach called Quantitative Evaluation of fertility of the tropical soils (QUEFTS) was also used to estimate the indigenous nutrient supply and attainable yield target of rice for different soil fertility domains. This model was applied as an alternate to extrapolate recommendations in areas where field data were not available, considering large financial and human resources required otherwise to conduct numerous field trials across different soil types and agro ecological zones. The model was validated with field trial data before making extrapolation of the recommendations. The QUEFTS model used soil properties from Nepal’s first digital soil map to identify nutrient status and deficiency.

In addition to agronomic optimum rate, an economic analysis was also conducted to see economic variability of the recommendations.

The newly developed recommendations provide guidance for balanced fertilization as it includes micronutrients zinc and boron, and organic inputs in addition to three major nutrients —Nitrogen, Potassium and Phosphorous (NPK). Results from field trials suggested that the new recommendation could increase rice productivity by 10-30% compared to existing farmers’ practice.

Advocating for endorsement

A three-day workshop was organized by CIMMYT and NSSRC to primarily share and approve the recommended fertilizer dose for rice crop as well as its relevance to achieve potential yield at farm level. Rajendra Mishra, joint secretary of MoALD inaugurated the event that was chaired by the Director of NARC’s Crop and Horticulture Research. Workshop attendees included MoALD, NARC, Department of Agriculture, USAID Nepal, secretaries from the Province Ministry of Land Management, soil scientists, university professors, agronomists and other high-level government officials.

During the workshop, NSAF explained the application of QUEFTS model with reference to the case of rice based on the field trial data for domain specific fertilizer recommendations. Shree Prasad Vista, soil scientist at NSSRC, summarized the results for rice as the approach and facilitated its approval from MoALD. The participants also discussed on strategies to link with the extension system to reach a large number of farmers through the three-tier governments. Fourteen research papers on nutrient management for major cereal crops were also reviewed at the event.

“I congratulate NARC for this historical work on updating the fertilizer recommendations after 46 years. Now, we are moving towards sustainable soil fertility management by adopting site-specific fertilizer recommendations,” said MoALD Secretary Govinda Prasad Sharma.

Although the recommendation for rice was a significant output of the workshop, fertilizer recommendations for other major crops will be carried out following a similar process.

NARC’s Executive Director Deepak Bhandari commented, “It is our pleasure to move from a blanket approach to site-specific approach. This is a milestone for agricultural research in the country and I would like to thank all the scientists, NSAF project and USAID’s support for this notable achievement.”

Similarly, speaking at the event, Jason Seuc, Director of Economic Growth Office at USAID Nepal, emphasized the importance of soil fertility management for achieving food security targets set by the Government of Nepal. Seuc remarked that a sustainable soil fertility management is critical not only for food security but also for reducing the environmental pollution.
