Fire can influence the stability of many natural habitats via changes in biological, chemical and physical properties of soil. The aim of the present study was to investigate the effects of fire on some chemical properties and nutrients availability in a rangeland soil. To perform this research, a fired area with a five-month history and a homogenized area close to it without fire were selected...
