How can root nematodes be prevented?

How deep in the soil do nematodes live?

As with most soil organisms, nematodes are concentrated in the top few centimetres of the soil (0–20 cm) and in the rhizosphere around plant roots. They live in the thin films of water surrounding soil particles, as they require water to move.
