Soil testing for levels of carbon and nitrogen under three land-use regime

Key Messages
• Preliminary findings suggest that the adoption of a biological farming system may
have positive benefits for soil organic carbon storage when compared to a conventional
farming system. However, further research is required to verify these findings.
• Improving soil structure can improve plant growth through enhanced water-holding
capacity and water-use efficiency.
• To remain productive, soil fertility must be maintained. Farmers can enhance the fertility
of their soil by adopting practices that stimulate biological activity thereby releasing
nutrients that are important for plant growth and vigour.
• The C:N ratio of the soil can provide you with an insight into the nitrogen requirements
of your crop.
