Shea waste slurry as an organic soil amendment of tropical soils in the Tamale Metropolis, Northern Ghana

Infertile and less productive soil due to continuous cropping, poor soil management and other forms of land exploitation are mostly amended using inorganic fertiliser. Shea waste slurry (SWS) as an organic soil amendment material was applied to soils in two locations and its effect on plant primary and secondary nutrients evaluated. One-way diagonal method was employed in sampling soil from fields measuring 25...

Effect of biochar application on selected soil properties in Southwestern Nigeria

This study investigated the effect of biochar on dispersible clay and soil chemical properties. The treatments consisted of four rates of milled biochar (0, 450, 900 and 1344 kg/ha) arranged in a Completely Randomized Design with four replicates. Surface (0-15 cm depth) soil of Iwo (Sandy loam) and Egbeda (Loamy sand) soil series were collected from the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife,...

Effect of graded compaction of tilled and untilled sandy loam soil on growth and yield of maize

The performance of maize on tilled and untilled sandy loam soil, under different levels of compaction of 0, 2, 4 and 6 tractor-wheel passes in a humid tropical environment was investigated with a Massey Ferguson (MF) 90-disc plough, mounted on an MF 260 tractor. The experimentation had different aspects, respectively conducted in the field and laboratory, at the Rivers State University, Port Harcourt, Nigeria. The...

Assessment of selected soil physicochemical properties on different land-use systems and landscape positions at Hamesa watershed, Wolayita zone, Southern Ethiopia

The investigation was undertaken at Hamesa watershed of Wolayita Zone with the aim to assess the consequences of land-use systems and topography on the physical and chemical properties of selected soils. Surface soil samples taken at 0-15 and 15-30 cm depths from three land-use systems (enset, grassland and maize fields) were collected under three slope positions (upper, middle and lower). Both the clay and bulk density...
