They contribute to the formation of Humus, pronouced HYOO mus
The process is known as Pedogenesis. Erosion and siltation are two of the mechanisms that contribute to pedogenesis.
Parent material, climate, time, organisms and slope
One main way in which soil organisms contribute to soil formation is by maintaining proper nutrient levels in soil. For example, soil organisms decompose organic debris, from other organisms that are dead and decaying. There are 16-17 nutrients that healthy soil and plants need. Organic debris meets the carbon nutrient need.Soil organisms also break down toxic residues from the '-cides [pesti-, nemati-, miti-, herbi-, etc] and from soil drenches. So toxins don't stay around to make the below ground environment inhospitable.Soil organisms make nutrients available that wouldn't otherwise be available. Nitrogen is our most abundant element. But it must be soluble to be taken up by plants. Nitrogen fixing bacteria and nematodes process nitrogen so it can be taken in by plants. Bacteria feeding nematodes and protozoa then feed on, and excrete, the bacteria. What the bacteria have eaten thereby also becomes available, to contribute to soil nutrient levels.Another main way is by making air and water passagewaysin soil. Soil needs air and water space for proper nutrient processing and build up. They also need roots to grow, and open up even more air and water spaces.Each kind of soil organism has its role. For example, microarthropods and nematodes open up larger air and water pore spaces. Bacteria make glues to hold clay, organic matter, sand, and silt together. Fungi make glue and thread to further consolidate what the bacteria have done. This is known as the soil aggregate process.

Decomposition of dead organisms adds organic matter, or humus, to the soil; humus is necessary to support plant growth.
