Effect of Integrated Soil and Water Conservation on Selected Soil
Physicochemical Property and Factors Determining its Adoption in
Wulbareg District, Southern Ethiopia
Abstract
To overcome the problem of land degradation expanding the elephant
grass to the degraded land for soil and water conservation in
sustainable land management practice were better option for farmer.
Objectives are assesses the effect of integrated soil and water
conservation on selected soil physicochemical property and factors
determining its adoption in, Ethiopia. Materials and Methods
of data were collected through soil sampling, field
observation and household interviews. SPSS software version 21, the data
were analyzed using descriptive statistical. Survey data was analysis
for continuous variables by using independent sample t-test and for
dummy variable chi-square and logistic regression to determine the
predictive variable. Results, Based on the finding sand, silt and
clay contents were varied significantly (P < 0.05) between the
land management practices. There was significantly higher mean bulk
density value for the soil bund compared to the values for the rest of
the land management practices. When comparing the soil bund with
elephant grass to the soil bund without elephant grass, the mean value
of hydrogen power was much higher. The trend was similar for total
nitrogen, available phosphorus. Furthermore, sex, total tropical
livestock unit, and information about agriculture were significantly
influenced adoption of soil and water conservation technology (elephant
grass). Main finding the soils under the bund with elephant grass
revealed that overall change towards the direction of increasing their
fertility status compared to soil bund alone. Thus, stabilization of
bunds with elephant grass significantly benefit to the soil for its
fertility improvement.
