The misleading fallacy of, higher the chemical fertilizer higher the yield therefore, better the income be. Have triggered in an over usage of chemical fertilizer more than the recommend standard. This has created in a self-pressuring situation among farmers in developing countries. This vulnerability occasionally leads into a decision-making situation where both life and death are seen as viable options. Hence in order to safeguard the farmer, with the aims of educating these disobedient farmers, through the process of validating the existing chemical fertilizer standard. This research was carried forth in Sri Lanka, for the paddy farmer. The data were collected in a data triangulation, where a controlled experiment, two series of interviews and two sets of questioners were utilized. Both, quantitative as well as qualitative data and, primary as well as secondary data were collected. Depending on the nature of the data collection instrument, an experiment, thematic, descriptive and a correlation analysis were performed through statistical software applications. Further, a yield and a soil test was performed for the controlled experiment plots. By adjusting the parameters accordingly, this study could be used as a model by other countries, regions or crops. Finally concluding on a policy implication, to eliminate or reducing the chemical fertilizer over usage in developing countries. Further avenues for a managerial implication where the Balance of Payment could be used to positively stimulating a developing countries Gross Domestic Product to achieve sustainable economic growth in the long run are discussed.
