Abstract:-With dam construction thousand hectares of land are cleared off vegetation especially for the reservoir of the dam, there by subjecting the land to erosion, land degradation and poor fertility. Also with dam construction thousand tones of sediment are trapped within the reservoir of the dam and as such not allowed to reach downstream, thereby causing variation in soil nutrients (chemical constituent) in both up and down stream.
The aim of this research is to examine the effect of Goronyo dam on soil physical and chemical characteristic in upstream and downstream, both systematic and purposive sampling techniques were employed in taking the soil samples. Similarly the data generated after laboratory test was subject to both descriptive and inferential statistic. The findings shows that the soil in the area are predominantly sandy loam, (with an average value of 73.3% sand,10.8%silt and15.8%silt). And the soils were rated low in organic carbon content (0.77%), low Nitrogen content (0.084mg/kg), low phosphorus (0.89mg/kg), low calcium ( 0.95mol/kg), moderate in sodium and Magnesium and high in Cec (32.9cmol/kg). And in term of pH, the soils in both upstream and down stream was slightly acidic. In conclusion, the Goronyo dam has no statistically significance effect on soils characteristic in the area as there is little variation between soil parameters tested. The study recommended addition of both organic and chemical fertilizers for higher yield.
