Abstract/ Executive Summary:

The study finds out the requirement of chemical fertilizers and suggests the role of organic fertilizers for sustainable rice production based upon projection of rice production, consumption, demand and supply of fertilizers for the years of 2020, 2030, 2040 and 2050. The total requirement for commonly used three fertilizers, 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 fertilizers in the field level, the research suggests for increased usage of organic fertilizers.

Objectives:

To find out the requirement of chemical fertilizer and suggests the role of organic fertilizer for sustainable rice production based upon projection of rice production, consumption, demand and supply of fertilizers for the years of 2020, 2030, 2040 and 2050.

Methodology:

A number of studies have been conducted on sustainability in agricultural sector in Bangladesh. Most of these studies, however investigated the changes in rice yield under different treatment of fertilizers by various doses in the experiment fields. It is also studied on strategies for developing the fertilizer sector in Bangladesh for sustainable agriculture. The farmers of Bangladesh mostly rely on chemical fertilizers for higher production, without or less application of compost. Such a fertilizer management practice leaves a massive deterioration of soil fertility, resulting loss in organic content.

The present research estimates requirement of chemical fertilizers and focuses on the role of organic fertilizer in sustainable rice production in Bangladesh. The estimation has relied on the different published accounts released by the Bangladesh Bureau of Statistics (BBS) and Ministry of Agriculture (MOA) such as Handbook of Agricultural Statistics and Statistical Year Book of Bangladesh.

Achievement/Findings:

The sustainable increase of crop production for food sufficiency requires efforts to enhance the capacity of production system. All agricultural inputs involved directly or indirectly in crop production need to be adequate and accessible at farmers’ field level during the growing season. Timely supply and availability of fertilizers at reasonable prices at the doorsteps of the hard working farmers in the country is necessary for optimum supply of nutrients to the depleted soils, for successful achievement of the targeted yield. According to the study, a linear correlation is there among the fertilizer application, the cropping intensity and high yielding varieties. In 2008-09, high yielding varieties covered more than 72 percent of the total cultivable land areas in Bangladesh. Similarly, cropping intensity has increased dramatically in the last decades and increased more than 23 percent in the last 15 years. The study also suggests that the demand of chemical fertilizers have become significant which has a negative impact on soil fertility as well as sustainability of crop production. In 1985-86, fertilizer has contributed 36 percent to the total soil fertility whereas in 2002-07, this contribution was 40 percent. Thus, the increasing response of fertilizers over the time indicates the degradation of soil fertility. Therefore, it is urgent to conserve and add nutrients to the soil through the balance application of compost and inorganic fertilizers, which can help, maintain and increase the nutrient reserves of the soil. Moreover, the prices of the imported fertilizers will continue to increase in the upcoming years due to high price of oil in internal market, and shrinking natural resources for fertilizer production. Therefore, mobilization of all organic resources and recycling them into soil fertilization programme can be considered. Besides, government can take some public awareness through media activities and advocacy to influence farmers in using balanced dose of fertilizer and can emphasize on the use of organic fertilizer for a sustainable rice production.
