Extent of natural soil cadmium, its bioavailability, and pollution treat analysis in the agroforestry systems of the Gedeo Zone of southern Ethiopia.

The research objectives were to determine extent of soil cadmium (Cd) in the major soil types of the Gedeo Zone of Ethiopia thereby assessing the pollution risk on the environmental health. Four profile pits representing Luvisols, Nitisols, Cambisols, and Leptosols, were excavated and soil samples were collected. Total and available Cd, Cu, Zn, and Mn, including other major soil physicochemical properties, were analyzed in the lab.

The Potential Role of Arbuscular Mycorrhizal Fungi in the Restoration of Degraded Lands.

Experiences worldwide reveal that degraded lands restoration projects achieve little success or fail. Hence, understanding the underlying causes and accordingly, devising appropriate restoration mechanisms is crucial. In doing so, the ever-increasing aspiration and global commitments in degraded lands restoration could be realized.
