This book contains reports of participants in the second meeting in a series on soil test calibration in West Asia and North Africa. The reports are on findings related to correlations between NaHCO3-extractable P in the soil and responses by barley and wheat to applications of fertilizer. The reports clearly reflect the key role played by the two cereal crops in the region and highlight the P-deficient status of most unfertilized agricultural lands. Complementing these reports are studies on response of food and forage legumes to phosphorus fertilization on soils in the region and on correlations between the Olsen method of extracting P(NaHCO3) and other cheaper and less time-consuming methods. Soils are classified according to whether cereals and legumes could be expected to respond to applications of phosphate fertilizer. Recommendations which may result in better allocation of phosphate fertilizer and major savings to the farmers and agricultural departments in the region are also included.
