The report highlights ongoing pilot-plant studies conducted by IFDC researchers in collaboration with Behn, Meyer & Company (Pte) Ltd., based in Singapore. The aim is to develop a process for granulating multi-nutrient-N, P, and K-fertilizers using raw materials available to Behn, Meyer. The researchers focus on producing homogeneous granular NP, NK, and NPK products utilizing prilled urea, phosphate rock, and potassium chloride as primary nutrient sources. Pilot-plant tests are underway to validate the feasibility of granulating different fertilizer grades, determine equipment requirements, and establish optimal operating parameters. Additionally, the report addresses the challenge of inoculating nitrogen-fixing bacteria to enhance soil fertility in leguminous crops. IFDC, in collaboration with scientists from Mississippi State University, is researching innovative approaches to improve the survival of bacteria when applied alongside fertilizers. Preliminary work has shown promising results, demonstrating that nitrogen-fixing bacteria can survive in fertilizer granules containing phosphate and potash when specific biological safe carriers are incorporated. Furthermore, the report discusses IFDC's involvement in technical assistance programs worldwide. Examples include the collaboration with PT PUSRI in Indonesia to provide engineering input for the design of a granulation unit and the partnership with the Bangladesh Agricultural Development Corporation (BADC) to enhance fertilizer distribution and marketing. These initiatives aim to alleviate constraints and promote the equitable and efficient use of fertilizers in agricultural practices. Lastly, the report provides an overview of the global fertilizer situation, highlighting the expected supply of nitrogen and phosphate fertilizers until 1985. While the supply of nitrogen and phosphate is projected to be sufficient, concerns arise regarding potential future shortages of potash. The study emphasizes the need for developing countries to increase their domestic fertilizer production to meet growing demand, which is anticipated to rise to over 135 million tons by 1985.
