A compacted soil will look like a dense layer or section of soil within the soil profile where the soil particles are packed close together, decreasing pore space and increasing bulk density. In a compacted soil the large pores that exist both around the aggregates and within the aggregates, are reduced.

WebCompaction is caused by excessive load or traffic on a soil and by natural processes. Soil conditions, including moisture, organic matter and the presence of living roots from crops or cover crops, affect a soil’s resistance to compaction. Some soils are more prone to soil compaction than others.
