Mix and aggregate soil. As they consume organic matter and mineral particles, earthworms excrete wastes in the form of casts, a type of soil aggregate. Charles Darwin calculated that earthworms can move large amounts of soil from the lower strata to the surface and also carry organic matter down into deeper soil layers.
Many kinds of nematodes live in the soil under any home lawn. Most of these soil nematodes are beneficial, feeding on bacteria, fungi, or other microscopic organisms found in soil (http://entnemdept.ufl.edu/creatures/nematode/soil_nematode.htm).ematodes are unsegmented roundworms, different from earthworms (http://entnemdept.ufl.edu/creatures/MISC/MISC/Earthworm.htm) and other, more familiar worms. Nematodes living in soil are very small, and most can only be seen with the aid of a microscope (Figure 2).
