Effects of Disc Ploughing on the Morphological and Physical ...

4.0 CONCLUSION AND RECOMMENDATIONBased on the given conditions under which this work was carried out, the result <strong>of</strong> theresearch indicated that, the soils <strong>of</strong> the study area are mostly sandy loam which areunaffected by actions <strong>of</strong> disc ploughing on the furrow slice. It can then be concluded that,disc ploughing on a short time and on single implement passage has little or no effect on themorphological and physical properties <strong>of</strong> the soils.Based on the findings <strong>of</strong> this study, the following recommendations were made:i The use <strong>of</strong> light duty disc plough should be encouraged since it has no adverse effects onthe furrow sliceii. Study should be extended to cover long time effects <strong>of</strong> disc ploughing on the physical andmorphological properties <strong>of</strong> the furrow slice.REFERENCESAbubakar, M.
