“…The N t content detected in the soils of the forest ecosystems studied by us indicates a positive relationship with altitude, or FVG ( R2 = 0.811). A significant correlation ( p ≤ 0.05) of total topsoil nitrogen with altitude was also found by Kidanemariam et al [ 64 ] in the Tsegede highlands of the Tigray region of northern Ethiopia and Hailemariam et al [ 48 ] in a less accessible Sida Forest, southern Ethiopia ( r = 0.44; p < 0.001). Malik and Haq [ 65 ] report that at altitudes of 900–2600 m in a part of the western Himalayas, only the N content showed a significant positive correlation with altitude ( r = 0.924, p ˂0.05), while all the other soil nutrients showed a non-significant negative correlation with it.…”
