dc.description.abstract The study of the durability and performance of cereal agriculture in arid areas pass through the study of agricultural production systems, their dynamic evolution and impact of agricultural activity on the soil.Our work conducted in the region of Hassi El F'HEL ( Ghardaia ). Is to study the spatial variability of organic matter following a systematic sampling on a regular grid by comparing the data of two plots used for 20 years to an uncultivated land.Results revealed that the analyzed soil is very poor to moderately poor in organic matter. Analysis of annual rate of change has revealed a very highly significant increase in the organic matter of the soil.Thematic analysis has shown a moderate spatial variability for cultivated lands and very high for non- cultivated lands. The geostatistical modeling showed, from the experimental variograms, a trend toward homogenization of the spatial variation of organic matter after agricultural intensifications. EN_en
