Cultivation of catch crop as a sustainable way of reducing CO2 content in the atmosphere

The catch crop cultivation seems to be a viable way for reducing carbon dioxide (CO₂) concentration in the atmosphere. The average global temperature is still growing, which is correlated with increasing concentration of green-house gases, mainly CO₂ in the atmosphere. The control of CO₂ exchange between the atmosphere and the terrestrial and marine ecosystems is a promising way, for removing CO₂ from the atmosphere. The species used in the mixture should have different types of root system, which are characterized by different depth. This causes that the soil is enriched with organic substances on several levels. Additionally, such a differentiation allows the nutrients from different depths to move up the soil profile, along the roots, to the ground parts, where they become again available for the main crop plants. Use of the ground-cover plants is a promising option for sequestering the carbon in the agricultural systems.
