Download Analysing soil carbon measurements in hill country from three slope positions and three aspects under contrasting fertiliser and grazing management: Ballantrae field trial (1975-2014)

This research strongly supports the idea that soil C stocks are stable under permanent pasture. They are not influenced by P fertiliser inputs and sheep grazing but are influenced by slope and aspect. Understanding landscape attributes is an important factor in assessing soil C stocks. A spatial nutrient budget model was developed. The model could form the basis of a farm scale C accounting tool by linking the soil C measurements to the animal production system.
