Caractérisation physico-chimique de la matière organique dans la région de Noumerate (Wilaya de Ghardaia)

Abstract

Our work has focused on the study of the physico-chemical characteristics of organic matter in the Noumerate region (Wilaya of Ghardaïa). The results of physical and physico-chemical analysis of study site that conducted on the soil and litter, show that before the annual fall of fraction of the tree (leaf, twigs, bark, fruit .... The most important percentage is the leaves for (record 1 contains the Casuarina equisetifolia tree and the 2 record contains Acacia raddiana), and the soil texture is sandy (R1 and R2) with considerable hygroscopic humidity. As well as, have a neutral to alkaline pH. Electrical conductivity. These are unsalted with an increase in organic matter content accompanied by a high organic carbon content.
