Information - SSS18 Organic wastes composting and application to soil - analytical, agricultural and environmental issues
High amounts of organic wastes of agro-industrial and municipal origin containing different concentrations of organic carbon (energy) and nutrients are daily produced mainly in “developed countries”. These biomasses can be properly blended and composted in order to stabilize the organic carbon, to increase the humic and humic-like materials and to sanitize the final product.
The use of compost is particularly recommended in those soils where the organic matter content is low. In recent years compost can partially substitute peat in growing media. In particular, the addition of stabilised organic matter rich in humic and humic-like components and nutrients to the soil contributes:
i) to nutrient cycles in the environment;
ii) to improvement of the soil fertility;
iii)to enhancement of the carbon sink (stock);
iv) to decrease the greenhouse gas emissions;
v) to retrieve nutrients.
The aim of this session is to focus the chemical, biochemical, microbiological, agronomical and environmental aspects involved in the use of compost in soil and growing media with contributions covering a wide range of related items.
