Spatial variability and classification of soils on a Legon hill catena in the Accra Plains, Ghana
Properties of five soils developed on different positions of a Legon hill catena in the Accra Plains, Ghana, were studied. Nyigbenya, Toje, Adenta, Haatso and Alajo series were located on the higher upperslope, lower upperslope, middle slope, lower slope and bottom slope positions, respectively. All the soils had bulk density between 1.00 and 1.40 Mg m-3 and pH (KCl) > 5.1. Alajo series showed relatively higher pH...

Soil properties and carbon sequestration under desert date (Balanites aegyptiaca) in the lowlands of Northern Ethiopia
This study assessed the effect of Balanites aegyptiaca on soil properties and carbon sequestration. A 100 × 100 m plot of entirely the same biophysical setting was delineated. Nine trees of relatively the same diameter at breast height (DBH) were selected to study the effect of the tree on soil properties. In total, 81 soil samples were collected from three radii distances from each tree, that is 0 - 2, 2 - 4, and...

Biostimulation of hydrocarbon utilizing bacteria in soil contaminated with spent engine oil using banana and plantain agro-wastes
hydrocarbon utilizing bacteria in soil contaminated with spent engine oil, as an alternative to inorganic fertilizers was investigated. Two types of agro-wastes were used for biostimulation of hydrocarbon degraders in soil contaminated with 10% w/w spent engine oil. 100g w/w each of plaintain and banana agro-wastes were supplemented and mixed with spiked soil. The rates of biodegradation of the oil were studied for a...
