Assessment of the Growth of Leucaena (Leucaena leucocephala) Seedlings on Amended Tailings
The study basically sought to find a substitute to the overburdened topsoil stockpile; the only source of soil for nursing seedlings in Noble Gold BibianiLimited. Tailings were collected from the mine tailing storage facility (TSP)and filled into 15 polybags, tailings amended with topsoil in 1:1 ratio were also filled into 15 polybags as well as topsoil from stockpile were also filled into 15 polybags. Seedlings of Leucaena leucocephala were raised on the three media and observed for ten weeks with readings on height and diameter taken each fortnight. The dry matter weight was taken on the tenth week. A comparison of the treatments showed that seedlings on tailings amended with topsoil had the highest growth in terms of height, diameter and dry weight, recording an average of 54.7cm, 0.5cm and 2.04g for height, diameter and dry weight respectively as against 36.3cm, 0.5cm and 1.57g in seedling on the topsoil. In conclusion, amended tailing soil significantly support the growth of L. leucocephalaseedlings and could be used as substitute to topsoil from stockpile.
