Abstract
Background
• in situ deeply weathered granite profiles (Fig. 1) are common in South-Western Australia (SWA) (Fig 2).
• Roots of native trees penetrate up to 40m (Fig. 3) to access ground water.
• Deep soil carbon (>35 m) has recently been quantified in SWA (Fig. 4). This deep carbon accounts for up to five times more carbon than current world estimates (<30 cm).
• Deep rooted native vegetation in SWA has been replaced by shallow rooted annual crops (20.5 m ha) (Fig. 2iii).
• The composition, age and stability of this deep carbon is unknown. The impact of agricultural practices on deep carbon is also unknown. Here we report on the composition of deep soil carbon for one profile.
