1. Soil fertility characterization and mapping for Adigudem plain, Northern Ethiopia

As Ethiopia’s agriculture has been influenced by variability and poor soil fertility management and information, thus this study was aimed to determine the physico-chemical properties of soils and build geo-referenced soil information systems so as to have precision agriculture for adigudem plain. An area of 229 km2 comprising different villages was delineated for the study. Soil sampling points were arranged in a grid form and georeferenced using a hand-held GPS. A total of 194 Soil samples... G. Berhe
