General Course Questions

Nematodes (but not mites) feed on bacteria and due to their low N requirement nematodes release surplus of N into soil solution, which then becomes available to other organisms (including plants)

Mites perform other functions such as shredding & mixing of soil material, the also do a bit of burrowing. The can also enhance aggregate formation by ingesting mineral & organic soil particles.

Heterotrophic bacteria decompose organic matter and by doing that they help with the release of the available forms of N, S and P.

All soil organisms also add to the pool of soil organic matter once they die
