摘要

本文提出了发展孟加拉国可持续农业化肥部门的战略方案。根据未来土地利用状况和可能的种植模式,估算了不同肥料(尿素、磷酸二铵、TSP、SSP和MOP)的预期需求量。考虑到该国不同肥料的生产能力以及工厂的条件与估计需求相比,孟加拉国立即需要增加尿素(1122,000吨/年)、SSP(960,000吨/年)、磷酸(226,000吨/年,100%磷酸)、硫酸(100万吨/年)和钾肥(70万吨/年)的额外生产能力。增加这些产能的估计投资将在1860万美元左右。如果不建立这些额外的能力,包括主要谷物在内的各种肥料的进口成本每年将超过1700亿美元(肥料≈9亿美元)。如果设想的增加能力的项目得到实施,这将使农业具有可持续性,减少对化肥进口的依赖。DOI: 10.3329/cerb.v13i2.3126化工研究通报Vol.13 2009 39-46

Strategy for Developing the Fertilizer Sector in Bangladesh for Sustainable Agriculture
A strategic program for developing the fertilizer sector in Bangladesh for sustainable agriculture is presented in this paper. Based on the land utilization and likely cropping patterns in the future, the expected demands for different fertilizers such as urea, diammonium phosphate, TSP, SSP and MOP have been estimated. Considering the production capacities of different fertilizers in the country as well as the conditions of the plants against the estimated demands, Bangladesh immediately requires to add additional production capacities for urea (1122,000 tpy), SSP (960,000 tpy), Phosphoric acid (226,000 tpy, 100% P 2 O5), Sulfuric Acid (1000,000 tpy) and Muriate of Potash (700,000 tpy). The estimated investment for adding these capacities would be around US$ 1860 million. If these additional capacities are not built, the costs for import of different fertilizers including staple cereals would be in excess of US$ 1700 (fertilizer ≈US $ 900) million every year. If the envisaged projects for adding capacities are implemented, this will make the agriculture sustainable and less dependent on import of fertilizers.
