Understanding the evolution of hydraulic parameters during the different stages of crust formation is necessary to predict infiltration in crusted soil. However, only a few studies have focused on the dynamics of parameters that control infiltratio

Many soils in South Africa have low nutrient supply, poor structural stability and are prone to soil erosion due to susceptibility to surface sealing and crusting. Two crusting soils from the Eastern Cap

Cyanobacterial crusts developing on the sandy and loamy soils of fallow lands in the Sahel (Niger) were investigated for their potential to fix nitrogen. Three sites were selected in this and environment, differing in sediment type and species compos
