PROJECT

Role of soil microorganisms

Understanding how soil amendments can maximise nutrient efficiency and soil health

This project will investigate the roles of soil organisms in nutrient cycling in horticultural and agricultural production systems for a range of soil amendments and crop rotations. It will include understanding the potential of novel organic fertilisers reliant on microbial processes and how to harness their use in nutrient release to meet the requirements of plants.

The research will increase understanding of how balanced soil amendments can maximise nutrient use efficiency with a focus on soil health. It will collaborate closely with Wide Open Agriculture, which is establishing diversified agricultural systems in the Wheatbelt of Western Australia.

The project will emphasise protecting and extending biodiversity, improving soil health and restoring waterways. The role of efficient nutrient use in such systems will be the focus on how to maximise contributions from soil biota in parallel with sustainable nutrient inputs to develop and sustain soil biological fertility whilst maintaining productivity.

Research team leader: Emeritus Professor Lynette Abbott

My area of research expertise is in soil health, soil biological fertility and plant-microbe interactions, including the roles or arbuscular mycorrhizal fungi in agricultural soils. My research focuses on the role of soil biological processes linked to the efficiency of nutrient acquisition by plants and includes bio-chemical and bio-physical interactions associated with organic and mineral soil amendments.
