The papers presented in this volume represent the proceedings of the Soil Fertility Meeting at Tel Hadya held during 19-23 November 1995. That meeting was, in essence, a continuation of the previous Soil Test Calibration workshops held in Aleppo, Syria (1988), Ankara, Turkey (1987), Amman, Jordan (1988), and Agadir, Morocco (1991). The meeting was a turning point in the WANA dryland soil fertility research. The participants reviewed and took stock of what had been accomplished in soil fertility research, and looked to the future and assessed what needs to be done. The meeting agenda represented a large degree of success in both endeavors. New issues to be addressed included a holistic concept of soil fertility as reflected in rotation trials; the use of N-15 to elucidate the dynamics of supplemental irrigation; the use of P in rangelands; assessment of micronutrient stress in terms of deficiency and toxicity; breeding to adapt crops to nutrient stresses, assessment of soil tests and laboratory management, practical considerations for soil fertility trials; aspects of soil fertility education; and economic assessment of fertilizer use policy. The meeting differed from previous ones in that a considerable part of the program was devoted to group discussion. The meeting was also characterized by the diversity of participants. In addition to a cross-section of ICARDA scientists from several programs and representatives of Syrian institutions and 13 other WANA countries including Ministries of Agriculture and universities, the meeting attracted several international institutes: Food and Agriculture Organization, International Potash Institute, and International Atomic Energy Agency, and the co-sponsor, Institut Mondial du Phosphate
