ABSTRACT
This qualitative study of the soils of the Zaër region is part of a context of good development, preservation and sustainability of agricultural soils. Its aim was to establish a reference framework for the physico-chemical characteristics of the region's agricultural soils. It was based on a spring sampling campaign carried out in 2021. Composite samples taken from thirteen sites with diverse soils were analysed in the laboratory. The soil analysis results were compared with reference values. The soils examined were moderately acidic to moderately alkaline, with low levels of organic matter. Nevertheless, the concentrations of exchangeable calcium and magnesium were found to be sufficient, while sodium levels were very low. Furthermore, cation exchange capacity was low in spring, reflecting the high and low nutrient retention capacity of soil, respectively. Phosphorus and potassium levels appear to be low. In the light of these results, the use of organic and mineral fertilisers and calcium amendments is strongly recommended to improve agricultural quality and productivity in the region studied.
