The soil resource provides 99.7 per cent of all human food. With the global human population growing rapidly, food security remains one of the three greatest challenges faced by society over coming decades. It's estimated that for existing agricultural land, the amount of food produced must be doubled per unit area – little new land is available for expansion of agricultural production.

This research aims to examine the impacts of long-term agricultural production on soil chemical fertility. A range of novel approaches are used to examine changes in carbon (organic matter), nitrogen, phosphorus and sulphur within soils, giving consideration not only to the forms of these elements within soil, but also their availability to plants.
