  • 摘要:The objective of this study was to assess the impact of intensive agriculture on the physic-chemical quality of water and soil. We have conducted a qualitative study of waters and soils of the irrigated perimeter of Sfafaa located in the province of Sidi Slimane, Gharb (Morocco). The approach includes campaigns of measurements in situ (pH and depth of the water table) as well as the analysis in the laboratory to determine the physic-chemical parameters of soil. Seventeen water points and soil were prospected over a period, starting from March to June during two years (2013 and 2014).Data were statistically analyzed using the method of analysis of variance (ANOVA).The results showed that the depth of water table varies between 9 and 12 m. In addition, that 70.6% of the studied wells were highly to extremely saline and then inadequate for irrigation. As regards the physic-chemical characteristics of the soil, the results show that the samples are poor to moderately poor in organic matter but contain high levels of potassium. Concerning phosphorus, the levels are low to high. On the other hand, we found a significant difference between 6 zones in terms of pH, pH(KCl), the K2O and electrical conductivity. The use of waters with poor quality for irrigation leads the problem of degradation of soils by accumulation of salts. This accumulation is more-or-less important as a function of the quality of water, the nature of soil, the climate and the mode of irrigation.
