ABSTRACT In order to improve man-made biological soil crusts (BSCs) for desertification control and develop value-added utilization of bioenergy byproducts, preliminary experiments were carried out to understand the effect of biochar addition on algae growth in sand. Microcoleus vaginatus was chosen as the model algae and cultivated in sand with various contents of biochar (0%, 2%, 5%, 8%, an...
