dc.description.abstract | Effectiveness of two soil types found at Sagana, Kenya, black clay soil (eutric Vertisol) and a red clay soil (chromic Cambisol), in retaining nutrients from pond effluent was investigated. A laboratory experiment was conducted with soil columns containing either of the two soils. Pond effluent application intensities of 31, 81 and161 mm day-1
were tested on both soils. Both soils retained over 60% of total P from pond effluents, with red clay retaining 27% more P than black clay. At the high effluent loading rate, low % N removal was observed in both soils. Total N removal efficiency declined with time after 21 days at the high rate, and after that time no N removal was observed where red
clay was used. Black clay was more enriched by N than red clay, while P enrichment was higher in red clay than in black clay. It appears that land application can remove
substantial amounts of P and N from pond effluent. | en |
