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 (用来耕种、种植、养殖和收获农作物的机器。尽管有利于农业增产，但机械化仍然会对环境产生负面影响：深耕使更多土壤暴露于风蚀和水蚀侵害；农作物残余可能被重新犁回到土壤中；清除残余物可能导致土地严重丧失有机成分，从而加大土壤被侵蚀的风险。) |
