A diverse range of soil organims minimise the impact of pest nematodes via mechanisms such as predation, parasitisation, production of toxins or enzymes, competition for space and resources, entrapment, and inducing plant resistance.

Organic residues within the particulate organic carbon fraction provide a labile source of carbon for soil organisms to consume.

This review highlights the lack of field-scale evidence of benefits for many biological amendments with potential to be used in agriculture.

Environmental controls of soil fungal abundance and diversity in Australia’s diverse ecosystems
Journal article
Soil fungi are vital for ecosystem functioning, but an understanding of their ecology is still growing.

All organisms in soil occupy the pore space surrounded by mineral particles, plant roots and organic matter.

There is currently little evidence for efficacy of biological inputs within the broadacre dry-land grains context.
