Soil consists of five principle components; water, carbon, nutrients, organisms and organic matter. In healthy topsoil these components, complex in themselves, interrelate in complex ways to create one of the fundamental elements supporting life on the planet. Australian soils are typically deficient in organic matter, nutrients and carbon. Water retention capacity is below average. The activity of microorganism is impeded. Land management practices that promote the positive interaction of these components can promote increased food production, maintain sustainability and decrease the volume of atmospheric carbon.
