Estimation of Soil Loss Rates from Rill Erosion in Biu Area, Borno State, Nigeria
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 3
Abstract
A study on estimation of soil rates was carried out at six different locations (Kigir, Piku, Daura, Mirnga, Garwashina and Tum) in Biu Area under different soil types topography and vegetation. The objective of this paper is to assess the severity of rill erosion features in terms of soil loss rates, in Biu Area. The study was carried out on monthly and annual bases. At each location, three (3) soil samples were collected for laboratory analysis. Rill channel features (length, width, depth and slope) and conservation practices were measured at each site. Three rill erosion models namely; Measured, Empirical (conceptual), and RUSLE2, were used to measure the extent of soil loss. The water holding capacity, particle density, Ph, total nitrogen, available P, sodium, and K values were; 20.7–30.9 %, 2.30–0.55 gm-3, 7.39–7.00 %, 0.22–0.10 g /kg-1, 4.20–11.55 ppmm, 0.39– 1.31 cmol (+) kg, and 0.64–2.94 g-1 cmol (+) kg, respectively. The result of measurement of soil loss on both monthly and annual bases differed with significant (p 0.05) different among site. The monthly and annual mass of soil loss (MSL) was 1.400–150.810 kgha-1yr-1, and annual rates of empirical and RUSLE2 models revealed moderate to high reliability in prediction, with r2 values of 0.8568 and 0.6125, respectively. Geometric mean error ratio (GMER) and geometric standard deviation of error ratio (GSDER) of empirically estimated and RUSLE2, predicted were 0.8111 and 5.9084, and 280.874 and 20.072, respectively. Empirica- -lly estimated model had GMER close to one (1) and smaller GSDER and had the highest prediction strength in the study area.
