Effectiveness of Sugar Industry Organic Wastes in Reducing Soil Compatibility in Soils of Three Ethiopian Sugar Estates

Incorporation of sugarcane industry by-products into soil can reduce the susceptibility soils to compaction. However, significance incorporated filter cake and compost at different water contents time compaction using proctor test load is not well documented. In this context, study was conducted three Ethiopian sugar Estates in 2017 examine effect incorporation clay content on maximum dry density, total porosity MDD, critical moisture under laboratory conditions. Sugarcane residues were added rates 0, 7.75 g per kg soils. The results showed that bulk density with no residue achieved 15.94% for light, 25% medium 28.6% heavy clay. Filter rate 30 t ha-1 reduced compactibility induced by 0.7 PL light soils, 0.97 0.98 all types 0 application levels, attained a minimum value increased as increased. 4 27.6%, respectively, compared control. Nevertheless, content, 2.44 46.9% over control Therefore, it be concluded most effective reducing less than higher PL. Moreover, more cake. Finally, recommended machineries operation during seedbed preparation harvesting; shall made when below 0.60, 0.9 0.91 PL, after treating either or tentatively. order give conclusive recommendation further research studies are needed levels case both residues.
