Situation
Sri Lanka’s tea sector, a major contributor to national export income and rural livelihoods, faces persistent challenges related to soil fertility decline, dependency on synthetic fertilisers, and limited access to timely and affordable soil-testing services. These challenges compromise both productivity and environmental sustainability. This project addresses these constraints by evaluating the suitability of rapid soil diagnostic tools and by testing integrated nutrient management (INM) approaches that combine mineral fertilisers with organic amendments and biostimulants. The project implements coordinated on-station and on-farm trials to (i) assess the accuracy and reliability of portable soil scanners compared to accredited laboratory analyses, and (ii) determine the agronomic and economic impacts of INM relative to current farmer practices. Simultaneously a farmer survey will be conducted to capture knowledge gaps, decision-making processes, and adoption potential of soil diagnostic tools.
