Organic resources

Total carbon (C)

Total carbon is an estimate of the amount of organic matter. Organic matter helps soils retain moisture and nutrients, and gives good soil structure for water movement and root growth. It can be used to address the issue of organic matter depletion and carbon loss from the soil. The target range is ‘Depleted’ to ‘Ample’, see benchmarking for more information.
