agricultural machinery Machines utilized for tillage, planting, cultivation and harvesting of crops. Despite its benefits in increasing yields, mechanisation has clearly had some adverse environmental effects: deep ploughing exposes more soil to wind and water erosion; crop residues can be removed as opposed to ploughing back into the soil; removal of residues can lead to a serious loss of organic content in the soil, which may increase the risk of soil erosion | |
