Soil Physical Properties Enhancement Via Native Tree Species in Northern Ethiopia

Dozens of chemical fertilizer is produced in factors to maintain and reclaim soil fertility, but the reliance on artificial fertilizer alone is not advisable due to environmental pollution. . Thus, indigenous plant species can maintain soil fertility without any extra cost. The aim of this study was to examine the effect of indigenous tree species on soil physical properties. Three dominant indigenous trees species (Croton macrostachuys, Cordia Africana and Albizia gummifera) were considered. Soil samples were taken from different sampling points under crown of these tree species (mid of crown and edge of crown). One sampling point is included by far 30m from the selected tree as a control group. Soil sample was taken by using core sampler. Soil physical properties such as texture, structure, porosity, bulk density and moisture content were analyzed. Bulk density was determined as 0.73g/cm3, 0.75g/cm3 and 0.8g/cm3 for Albizzia gummifera, Croton macrostachuys and Cordia Africana respectively.
