INSFFER [International Network on Soil Fertility and Fertilizers Evaluation for Rice] promoted research and cooperation to increase fertilizer use efficiency and to improve and maintain soil fertility levels that will sustain high rice yields. National program scientists, IRRI [International Rice Research Institute], and the International Fertilizer Development Center (IFDC) collaborate in research trials, training and site visit tours. Twelve collaborative research trials dealt with topics that include fertilizer efficiency, long-term fertility, P sources, acid soils, azolla and integrated use of inorganic and organic fertilizers.
