Comparison of Soil Biological Activity in Forest with Coniferous and Broadleaf Trees in Biston Region of Kermanshah [PDF]

open access: yesمجله آب و خاک, 2022
IntroductionThe maintenance of planted forests in arid and semi-arid lands is important. Soil formation in forest ecosystems is different with different tree species. Tree species have a direct and indirect effect on soil organisms.
