| Abstract Seasonal soil-tool interactions, tractive wheeling and trailed tandem traverse of agricultural fields present ambiguities in defining and qualifying soil processing in tillage where the physio mechanical state of soil health is repeatedly perturbed. Precise and distinctive knowledge on quality characterization and mechanistic response behavior of soil-tool and soil-wheel interactions under tillage is sparse. We reviewed 116 state of art tillage studies in the US, Europe, UK, Australia, Africa, and Asia among others, concerning localized and integrated effects of soil-tool and soil-wheel interactions and associated dynamic response trends of mechanically distressed soils; to untangle and overcome persistent ambiguities in qualifying tilled soil... |

| Thin layer drying of cowpea leaves (Vigna unguiculata) and jute mallow (Corchurus olitorious L) (African leafy vegetables) was studied at different temperatures (40oC -100oC) in a convective laboratory dryer. The study determined the drying characteristics of the vegetables, the maximum drying temperature and the drying energy requirements. Moisture content of the African leafy vegetables was determined on dry basis and the data were used to calculate moisture ratios and drying curves were plotted. The drying occurred in the falling rate period. The experimental data were fitted to fourteen thin layer drying models and the most appropriate drying model determined using correlation coefficient, mean square error and standard error of estimate. The model... |
