Carbon sequestration by compost application

Compost is applied in agriculture to improve soil fertility by means of the supply of mineral fertilizers, such as potassium, phosphorus, and nitrogen. Moreover, the input of compost strongly influences the soil carbon storage which is also an important factor of soil fertility. This is due to the fact that composting partly results in the increased formation of stable carbon compounds, i.e. humus-like substances and aggregates. These are made of complex compounds that render them resistant to...
