In terms of restoring degraded land, the west of Niger has been characterised by major efforts for decades. The aim of this study, carried out on developed sites in the commune of Simiri (western Niger), is to assess the effects of structures on improving the physico-chemical characteristics of the soil in silvopastoral sites. The Satara plateau was the study site. On the plateau, a bench sub-site and a half-moon sub-site were selected. On the slope, two trench sub-sites were selected. In each site, structures were selected on transects to assess the various fertility parameters selected. The thickness of the particles accumulated in the structures was determined and a 10 cm core of soil was sampled for laboratory analysis. The parameters determined were particle size, pH, carbon, assimilable phosphorus and organic matter. The results showed that the average sediment thickness was 11.28 ± 3.51, 11.66 ± 1.88 and 14.6 ± 4 cm in the half-moons, benches and trenches respectively. Soil texture varies from sandy-loam to sandy-loam. The pH values range from 4.58 to 4.30, implying that the soils are extremely acidic. The soils are relatively rich in phosphorus (14.57 to 16.067ppm) and organic matter (1.20 to 2.26%). The study thus helped to consolidate the impact of land restoration works on soil fertility.
