Sediment accumulation (siltation) from soil erosion on farmland is a common environmental impact of agriculture. (a) is wrong — fertilizer runoff typically causes algal blooms and decreased oxygen. (c) soil compaction is usually caused by heavy machinery or livestock trampling rather than tillage loosening soil. (d) is wrong — herbicides reduce plant growth, not increase it.
