Worms and insect larvae make a significant contribution
to aggregation by burrowing through the soil in search
of food. They increase the air space and their fecal
discharge contributes to the soil soup.

This is all significant for several reasons keeping in mind Your Skyline
that aggregation will not occur in the absence of organic
matter. First, as stated above, the larger soil particles
represent a home for the microorganisms.
Second, the particles create air space reducing the soil
bulk density allowing for greater gaseous exchange and
drainage. Third, the particles act as sponges to hold to
retain water that will be released when plants need it.
