WebWhat does a compacted soil look like? 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 Soil compaction can occur at the soil surface in the form of soil crusting, or it can occur in the subsoil. Soil compaction is sometimes blamed for reduced crop productivity, but it is important to correctly diagnose the cause or causes of reduced crop production.

Compaction of soils results in decreased porosity within the soils, which decreases infiltration capacity. ... Results showed that this approximation does not affect the calculated infiltration flux because the diffusive flux is small and that the finite water-content vadose zone flow method ...

WebSoil aggregation is an essential mechanism for the stabilization of SOM, especially in organic soils (Lutzow et al., 2006). It affects soil physical (aeration), chemical (water infiltration), and biological (microbial) activities. If SOM is within soil aggregates, aggregate formation physically protects SOM from biological degradation.
