Key Facts about Soil Nematodes
- They are tiny invertebrates that play a vital role in soil fertility.
- Nematodes occur in all soils. Even in relatively poor soils, there are millions in every square metre.
- Nematodes feed on plant roots and on all the organisms that live in soil (e.g., bacteria, fungi, algae, diatoms, protozoans, rotifers, tardigrades, springtails, arthropods, oligochaetes and nematodes).
- They can be either beneficial or harmful to plants.
- Beneficial nematodes include free-living nematodes, which help decompose organic matter and recycle nutrients in soil.
- The ratio of bacterial- to fungal-feeding nematodes indicates the rate of nutrient cycling.
- Entomopathogenic nematodes work with bacteria to control pests.
- Nematodes are also valuable indicators of soil health, as they can help assess changes in soil conditions caused by disturbance or pollution.
