Abstract: The physico-chemical parameters of the soil surface horizons of six rice fields in the Gharb plain
(Morocco) show a variation between the beginning and the end of the vegetative cycle of the
studied rice. The clos are characterized by a basic pH related to submersion, an appreciable
content of organic matter and a variable sodicity associated with a strong cation exchange
capacity and secondly the nature of ground of the rice fields .
In Morocco, rice growing locates in the area of Gharb and Larache (North-West of Morocco).
The location of these rice plantations is due to the presence of three factors: a warm climate and
not very wet, proximity of the Sebou wadi where the pumping the water of irrigation is carried
out, and the propitious nature of the ground.
The objective of our work is to evaluate the physicochimical quality of surface waters of five
clos of the rice plantations of the area of Gharb in Morocco (town of Sidi Allal Tazi and Bil
Ksiri).
The analysis focused to 9 physico-chemical parameters of ground such as soil parameters such as
the hydrogen potential, limestone; texture , electric conductivity, Na+, CEC, MO, P2O2 et K2O |
