Summary, etc. |
The contribution of Croton macrostachys to soil fertility was studied in the traditional agroforestry system of the Bure area in northwestern Ethiopia. Three adjacent Croton trees having approximately the same size and age were selected on a cultivated farm. Soil samples were taken under the three trees at 50,150,300 and 800 cm (control) away from the tree base to a depth of 0-15 and 15-30 cm in four directions. Soil orgnaic carbon (Corg) and total nitrogen (Ntot) concentrations were low at the site. Available phosphorus (Pav), cation exchange capacity (CEC), and exchangeable cations (Mg, Ca, K, Na), Corg and Ntot were significantly higher under the canopy relative to the control among distances. Significant differences were also observed between depths in Corg Pav, and exchangeable cations (K, Ca, Mg, Na). A decreasing trend was observed for all parameters except N with increas1ng distance from the tree base at both soil depths. The decline was evident up to 300 cm from the tree base, indicating the potential area of inf1uence of the tree. |
