Effects Of Waste Water From Fish Pond On Some Selected Engineering Properties Of Soil (Case Study Of Mouau Fish Farm)

ABSTRACT

Field experiment was conducted during the raining season at the fish farm of Michael Okpara University of Agriculture. Umudike (MOUAU) on the sandy loam soil to test the effects of waste water from fish pond on the engineering properties of the soil. The experiment was carried out with the soil samples collected from the discharge point of the fish pond and the soil sample collected from a point away from the discharge point. The samples were tested for the following engineering properties of soil: bulk density, total porosity, moisture content, particle density. saturated hydraulic conductivity and Atterherg limits. The average result gotten from the affected soil are as follows: moisture content (20.93%), bulk density (1.40g/cm3). particle density (2.68g1cm3). porosity (47.65%). K \T (3.98 x 10 mis). For no affected soils, moisture content (16.06%), bulk density (1 .45g/cm3). particle density (2.3 Sa/cm3 ). porosity (39.1 %), KSAT (1.49 x I 6 mis). The study revealed that the fish pond waste water affected soil were clayed loam while the non affected soil were sandy loam soil. Waste water from fish pond was found to improve the engineering properties of the soil.
