Effect of Eucalyptus Globulus Woodlot Plantation on Selected Soil Physico-Chemical Properties, Wheat Yield in Wogera District, Amhara Region, Ethiopia

Currently, a Eucalyptus globule is common smallholder plantation species in the Wogera district. The significantly expanding on marginal and fertile farmlands. objective to analyze effects of globules woodlots their directions selected soil physicochemical properties yield wheat crop. Three with similar site conditions were for this particular study. Soil samples taken at depth 20 cm RCBD design three replications. four (East, West, South, North) five different horizontal distances from woodlots; center woodlot, 5 m, 10 15 40 m. For study: quadrates 1m2 area each distance within laid grain measurement. finding indicated that electric conductivity, available phosphorus, cation exchange capacity, texture, exchangeable cations not across distances, whereas bulk density, pH, total nitrogen, organic matter different. This could be attributed high addition via litter-fall, root biomass, uptake, return nutrients deeper profiles under tree canopies. biomass direction sampled woodlot increasing trend all directions, study recommends should planting lands appropriate croplands about 20m minimize its effect crop yields.
