    IFDC Report, Volume 10, No. 1
    (1985-03) IFDC
    This report highlights the advancements in developing the PHILPHOS beneficiation plant, which aims to utilize indigenous phosphate ore for fertilizer production in the Philippines. The project, initiated in 1981, addresses challenges related to the high magnesium, iron, and aluminium content of the Bantigue phosphate rock, which hinders its use in phosphoric acid production. Through extensive laboratory tests and pilot-scale attrition scrubbing, the quality of the Bantigue rock has been improved, resulting in a concentrate that meets commercial standards. Additionally, tests were conducted to determine the compatibility of the beneficiated Bantigue rock with commercial concentrates for phosphoric acid production. The findings provided the basis for PHILPHOS' decision to establish a large-scale production facility using manual sorting, scrubbing, and desliming. With readily available equipment and a simple process developed by the International Fertilizer Development Center (IFDC), the PHILPHOS beneficiation plant is set to achieve a rapid startup with minimal capital investment.

    IFDC Report, Volume 12, No. 1
    (1987-03) IFDC
    This report provides an overview of the work and progress at the International Fertilizer Development Center (IFDC) as of March 1987. It highlights various aspects of the center's activities, including access to plant germplasm, advances in agricultural technology, breeding materials for genetic control of insects and plant diseases, and training opportunities for scientists. Dr Haldore Hanson, Director-General Emeritus of CIMMYT, presented the Chinese viewpoint on the benefits of technical assistance by international agricultural research centres. The report also discusses the review of the Biological Nitrogen Fixation Project and the development of viable inoculants. Furthermore, it covers Dr John A. Hannah's lifetime achievement award and the establishment of the Travis R. Hignett Fund by the IFDC Century Club. The report concludes with the perspectives of Togolese officials on the IFDC-Africa Center and the annual workshop conducted by the West African Fertilizer Management and Efficiency Network.
