a two-year study was conducted in the negev region of israel, using the drip method, to determine the effect of four levels of water quality in combination with three soil amendment treatments (gypsum spread on the soil surface along the drip laterals after planting, injection of h//2so//4 into the water during each irrigation, and a control) on plant response, salt distribution in the soil profile, and soil sodification processes. the addition of soil amendments during the irrigation season, although reducing exchangeable sodium accumulation near the emitter, endangers the next crop by increasing sodium accumulation under the plant row. it is, therefore, recommended that the amendment be applied only before the winter.
