Evaluation of physico-chemical parameters of agricultural soils irrigated by the waters of the hydrolic basin of Sebou River and their influences on the transfer of trace elements into sugar crops (the case of sugar cane)

Abstract

This research was conducted in Kenitra (northwester n Morocco) to determine the physicochemical parameters and metallic concentrati ons at three levels: surface water of Sebou and Beht intended for irrigation, agricultura l soils and sugarcane. The spectrometric analysis of source plasma emission (ICP) has identi fied eight trace elements contained in the materials taken from zone 1 (As, Cd, Co, Zn, Ni, Pb , Cu and Cr). The obtained results showed that the interaction between the different physicoc hemical parameters of agricultural soils decides the transfer of the metal elements to the p lants. Indeed, for the soil which is used in this agriculture (for sugar cane), its irrigation w ater, and the contents of Cr, Cd and As exceeds the accepted standards.
