Qvidja aims at carbon-sequestering and biological cultivation, where the production input is as renewable as possible and pesticides are used as little as possible. Cultivation is started by allowing all fields to grow grass, which helps to heal the structure of the soil. The grass is used as fodder and as an ingredient in biogas production.
Carbon sequestration is not possible when artificial fertilisers and artificial biocides are used. That is when the below-the-ground biology does not work like it should, but allows carbon to escape.
Slowly, crop rotation is adopted and native species and nitrogen-sequestering plants play the main role. Plant rotation means that plants with different characteristics are continuously cultivated in turns on field segments. The approach utilises nitrogen-sequestering plants, improves the structure of the soil, restrains the growth of intrusive plants – previously known as weeds – and attempts to keep the soil covered by vegetation. Efforts are made to avoid tilling: it releases carbon from the soil into the atmosphere and reduces plants’ ability to sequester carbon.
