Increasing soil carbon levels
If soil carbon levels are lower than desirable, they may be increased in a number of
ways:
•
Manage the soil to maintain or increase soil crumb structure and soil pore
spaces.
•
Add carbon as stubble mulching, green manuring, compost, humates, fulvates
or molasses.
•
Maintain dense plant cover on the soil. Green plants add carbon.
•
When conditions are suitable, add suitable commercially available
microbiological products.
•
Encourage larger forms of life such as earthworms.
•
Do not use chemicals that will harm the microbiology already present or about
to be introduced.
•
Keep soil pH at around neutral, and balance soil cations.
•
Keep stock and machinery traffic on the soil to a minimum. Use rotational
grazing techniques.
•
Keep soil moist if possible.
•
Encourage good plant root development by shallow to deep ripping when
conditions are right.
