Soil organic matter (SOM) plays a key role not only in soil fertility and quality (by providing a number of physical, chemical, and biological benefits), but also in C cycling. The decline of SOM represents one of the most serious threats facing many arable lands of the world. Beside this, there is an imperative necessity of a sustainable management for the increasing quantity of organic waste. Crop residues and animal manures have long been successfully used as soil organic amendments to preserve and enhance SOM pools. During the last decade, pyrolysis (the combustion of biomass under low or no oxygen supply) is showing a promising approach for managing carbon-rich wastes such as sewage sludge, the pulp and paper industry residues or crop residues and to create added value co-products.
Besides serving as a source of organic matter and plant nutrients, these materials may contribute to fight plant diseases and reduce soil contamination, erosion, and desertification. A safe and useful application of organic amendments requires an in-depth scientific knowledge of their nature and impacts on the soil-plant system, as well as on the surrounding environment. While the benefits biochar or fly ashes as soil ameliorants and fertilizers are very well known, the knowledge of the use of other sorts of pyrogenic organic matter as well as the effects of biochar in SOM composition at a long term are very scarce.
This interdisciplinary session will focus on the current research and recent advances on the use of organic amendments including pyrogenic organic materials such as biochar or wood ash in modern agriculture as well as for the restoration of degraded soils, covering physical, chemical, biological, biochemical, environmental and socio-economical aspects by bringing together scientists from the diverse fields of soil, applied pyrolysis, bioenergy waste management, SOM characterization, carbon dynamics and plant nutrition.
