The Impacts of Mound-Building Termites on Micronutrients and Soil Hydraulic Properties in Parts of Borana Lowlands Southern Ethiopia

This study was focuses on the impact of mound- building termite on micronutrients and soil hydraulic properties in three districts of Borana zone. The condition of soil is in unfavorable condition when its physical, chemical and biological features have negative impact on environment. Knowledge on soil hydraulic properties and micro nutrient content for soils affected by termite mound and adjacent unaffected soil will give a clue on the impact of mound building termite for plant establishment. Infiltration rate for adjacent soil profile106.47 mm/hr (Moderately rapid) and for termite mound profile 142.13 mm/hr (rapid) infiltration rate has been observed while the packing density up to 1.80 t m -3 (high) for external part of termite mound which isgreater than 1.75 tm -3 and 1.36 t m -3 (low) for adjacent soil profile less than1.40 t m -3 . There is also higher concentration of manganese (Mn) and zinc (Zn) content on external part of termite mound for fine textured soil and no difference in copper (Cu) and Iron (Fe) content between termite mound material and adjacent soil. Generally, the termite mound has positive impact on soil hydraulic properties of soil and micronutrients in order to support plant establishments.
