EXTENT AND REMEDY ON GULLY EROSION IN BANGSHIKA AREA ADAMAWA STATE, NIGERIA

A study was carried out in order to obtain sufficient information regarding the severity of soil erosion in Bangshika area. The soil losses in each gully site were evaluated. Representative soil samples in their disturbed forms were collected from each location visited. Soil sample weighing 20 kg each in polythene bags were taken to the laboratory for analysis. Parameters related to soil erodibility were determined, these includes erodibility index, mechanical analysis, organic matter contents, permeability of the soils, soil structure, and aggregate stability. The results show that the area is prone to erosion. The bulk density, particle density and percentage pore space were found to be 332.4 kg/m3 , 418.6 kg/m3 and 20.60 % respectively. The volumes of soil loss in the gullies range from 697 to 3362 m3 in Dilguda and Gulang Nduson. The slope 5 ? 10 % in study area is generally undulating. Soil aggregate stability is from 6.4 to 23 MJ in Dilguda and Mugadiji.
