Biochar from PS pyrolyzed at 300˚C is recommended for southern Libya and other sandy soils in arid regionsiochar is a carbon-rich material made by carbonizing organic materials (e.g., manure, agricultural residues, etc.) in a zero or limited oxygen environment. The resulting material often has positive effects on soil physicochemical properties and plant growth, though the effects depend on feedstock, production conditions, and soil typesCHEMICAL AND PHYSICAL PARAMETERS O
