The role of Enset (Enset vetricosum (Welw.) in Soil rehabilitation
The rehabilitation of degraded soil and water resources will be critical in meeting future global food demand in the context of future climate variability and in addressing associated negative impacts on the environment that are a consequence of current agricultural systems. At the global level, combating soil degradation (soil rehabilitation) will help offset greenhouse gas emissions, provide a better environment, guarantee more food to an increasing population, and contribute to the economic progress of future generations. However, in Ethiopia there is practice of rehabilitating the degraded low-potential areas mainly by construction of physical soil and water conservation…show more content… It indicates that enset cultivation is sustainable system with regard to maintain soil fertility significantly higher in the enset field. This might be due to the materials added to the soil from the plant parts and organic farming (application of manure and domestic waste). Enset has highly degradable parts such as leaf midribs; pseudo stem sheath, Pseudostem core/ which are used to maintain soil fertility. Any practice of cultivating enset could improve soil structure. However, in some cases these improvements may not be sustainable at the time of scraping it, because of labor movement which may compress the soil. Enset can reduce soil erosion and land degradation. The root system and non-fertilizer cultivation are other important characteristics to protect soil erosion and land degradation. Some farmers cultivate enset in the face of flood and drain it in to enset farm in order to reduce further soil erosion (Chakoro Tamire, Mekuria Argaw). According (Chakoro Tamire, Mekuria Argaw(2015)) Soil laboratory analysis result revealed that enset field had significantly (p<0.05) higher level of TN (0.3%), OC (3.6%), Av. P (66.7ppm) and lower level of BD (1.2) than annual crop fields. Laboratory analysis of soil has shown that an average size of clay, silt and sand fraction under enset cultivation was 31.2%, 49.3% and 19.5%, respectively, while in the annual crop land the proportion of clay, silt and sand were 37.5%, 40.3% and 22.2%, respectively. The overall output from the research showed that enset has contribution in environmental rehabilitation (Chakoro Tamire,
