Future Fertiliser Demand and Role of Organic Fertiliser for Sustainable Rice Production in Bangladesh

摘要

The study finds out the requirement of chemical fertilisers and suggests the role of organic fertilisers for sustainable rice production based upon projection of rice production, consumption, demand and supply of fertilisers for the years of 2020, 2030, 2040 and 2050. The total requirement for commonly used three fertilisers, Urea, Triple Supper Phosphate (TSP) and Muriate of Potash (MP) may increase significantly due to compulsions for growing increased amount of crop outputs in small fragmented parcels of land in the context of diminishing cultivable lands in Bangladesh, negatively impacting on soil fertility as well as sustainability of crop production. Since sustainable yield of crop considerably depends on balanced application of both chemical and organic fertilisers in the field level, the research suggests for increased usage of organic fertilisers.
