Cartographie, de salinité dans une parcelle cultivée de la plaine de la Mina (Relizane)

Abstract

The salinity control, by the knowledge of its spatial distribution, is necessary in order to achieve sustainable agricultural development strategies. The conventional method of determining the salinity, By measuring the electric conductivity of an extract of the saturated paste of the soil (CEps), remains difficult because of the high spatial variability of the levels of salts from one point to another, which makes this laborious method. As an alternative solution, Electromagnetic induction by the apparatus (EM38), was developed by Geonics Ltd (Canada) and can be used to facilitate rapid soil salinity field measurements. It is fast and allows a high density of measurement points. This work aims to study the spatial and
