摘要：

The effect of irrigation with five doses of raw olive mill waste water (0, 2, 4, 6 and 8 liters / pot) on the growth of young olive trees (cv. Chemlali) grown in pots containing 16 kg of sandy soil has been studied. Preliminary results over a period of two years showed that, in consideration of its enriching effect on organic matter, nitrogen, exchangeable K and P, the possibility to use olive mill waste water to improve the soil fertility was an interesting process. A few days after irrigation with vegetation water, the soil showed an intense microbial activity and microbiological analysis showed a relative abundance of nitrogen fixers. Regarding the influence of the treatments on tree growth, waste water given to growing trees, in high doses (6 and 8 liters / pot) was phytotoxic and plants died. However, when the waste water was applied before planting, 100 % of the trees survived.
