Assessing the Challenges of Transitioning to Organic Fertilizers: A Case Study in Mahaweli System-B, Sri Lanka

Mahaweli System-B, spanning the Polonnaruwa and Batticaloa districts of Sri Lanka, underwent a major shift in 2021 with the introduction of a government-mandated organic fertilizer subsidy program. This change aimed to promote eco-friendly farming by replacing inorganic fertilizers that had been used for decades. However, the transition posed significant challenges for farmers, particularly in the Dimbulagala Block, a key agricultural area known for its extensive paddy cultivation. This study investigates the constraints faced by farmers during this transition and evaluates their attitudes toward organic farming. Data were collected through a structured questionnaire survey conducted with 100 randomly selected farmers from six units of the Dimbulagala Block. Results revealed several critical barriers, including difficulties in transporting, storing, and applying organic fertilizers in field conditions. Farmers also expressed concerns about reduced paddy yields when using organic fertilizers, compared to traditional inorganic methods. Despite the availability of organic materials and training opportunities, these logistical and practical challenges significantly hindered adoption. Moreover, the study found variability in farmers’ adaptability based on their age, education level, and farming experience. The findings highlight the urgent need for improved infrastructure, such as better transport and storage solutions, and enhanced farmer support systems, including targeted training and financial incentives. Addressing these limitations could increase the acceptance and effectiveness of organic fertilizers, promoting sustainable agricultural practices in Mahaweli System-B and beyond.
