Assessment of the Physicochemical Properties and Macro Nutrients of Surface Soil in Shewa Robit, Amhara Regional State, Ethiopia

Zelalem Getnet

This study was conducted in Shewa robit, Amhara Regional State, Ethiopia by collecting the composite samples to compare the three different study districts (Kebele 1, Kebele 2, and Kebele 3) during November- January 2013 cropping season. The study was made at a total of thirty sampling sites and each district covered 225m2 sampling area. Composite samples of surface soil were collected using special auger from a depth of 0-15 cm. The laboratory analysis results indicated that the electric conductivity, organic carbon, moisture content, bulk density, nitrogen, phosphorus and potassium of the soil were showed significant variations while, the soil pH and soil texture were not showed significant variations (P<0.05). As the phosphorus and organic carbon content was lower than the recommended level, it needs environmentally and socially acceptable integrated nutrient management practices like agro-forestry systems, crop rotation, organic inputs, chemical fertilizers, and improved crop varieties that can be adapted to local farming situation should be implemented for sustainable agricultural development in the study area.
