Background

Justine Cox is a soil Scientist for the New South Wales Department of Primary Industries and works predominantly in the horticultural arena. Her work includes research into soil issues for the macadamia, blueberry, vegetable, melon and banana industries. Justine has worked on soil erosion for the macadamia industry, mulches for the blueberry industry, including compost and biochar and is currently evaluating compost and biochar for soil carbon sequestration and greenhouse gas reduction in the banana, melon and blueberry industries. She has been involved in evaluating biological indicators for soil health, root assessments and compost for carbon. Justine believes in looking at soil as a living system, with an ecological approach in the agricultural environment.
