| Popis: | To investigate the relevance of biochemical parameters in biogeochemical mechanisms of the soil, it is important to gather data related to different soil types under different pedogeoclimatic conditions. In this study, we investigated on the calcareous agricultural soils in the Saiss plain (North Morocco). Four agricultural soils exposed to multi-metal (Cr, Cu, Zn and Ni) and organic matter contamination as a result of irrigation with Oued Fez and Oued Sebou waters that are affected by urban and industrial activities around the city of Fez, were studied and compared to a reference site irrigated with uncontaminated water.The study concerned soil physicochemical proprieties and the activity of a range of enzymes (phosphatase (PHOS), arylsulfatase (SULF), urease (UREA), arylamidase (AMID), β-galactosidase (GALA), glucosidase (GLUC) and laccase (LACA)) related to nutrients cycles. Pearson's correlations between these parameters showed that soil enzymatic activities (PHOS, SULF, UREA, GALA, GLUC and LACA) were correlated positively with heavy metals (Cu, Zn and Cr) concentrations in the soil and also with dissolved organic carbon (DOC) and negatively with the aromaticity (AROM) of these compounds. Interestingly, analysis of intra-site correlations showed strong relationships among enzyme activities in the reference soil, while in contaminated soils these activities were largely unrelated to each other.It was concluded that soil irrigation with heavy metal and organic matter contaminated watercourses over decades has resulted in soils with high enzymatic activities function and nutrient turnover but altered relationships among geochemical cycles. |
