Resumo(s)
Key priorities in biochar research for future guidance of sustainable policy development have been identified
by expert assessment within the COST Action TD1107. The current level of scientific understanding (LOSU) regarding
the consequences of biochar application to soil were explored. Five broad thematic areas of biochar research were
addressed: soil biodiversity and ecotoxicology, soil organic matter and greenhouse gas (GHG) emissions, soil physical
properties, nutrient cycles and crop production, and soil remediation. The highest future research priorities regarding
biochar’s effects in soils were: functional redundancy within soil microbial communities, bioavailability of biochar’s
contaminants to soil biota, soil organic matter stability, GHG emissions, soil formation, soil hydrology, nutrient cycling
due to microbial priming as well as altered rhizosphere ecology, and soil pH buffering capacity. Methodological
and other constraints to achieve the required LOSU are discussed and options for efficient progress of biochar research
and sustainable application to soil are presented
