“…3A, and Table 1). Previous studies reported an increase in bacterial abundance and altered microbial communities after BC addition under controlled laboratory conditions, which was attributed to the physic-chemical properties of BC (e.g., sorption, pH, chemical properties, habitats) (Anderson et al, 2011;Hale et al, 2015;Pietikäinen et al, 2000). However, such short-term positive effects of the physico-chemical properties of BC on microorganisms under controlled laboratory conditions were not as notable in our long-term field study.…”

“…The FCB treatment had the highest AWCD compared to all other treatments during the 168 h of the Biolog culture (Figure 4a). The promotion of microbial populations and Biolog AWCD values after biochar and compost application might reflect the improved nutritional conditions (Watzinger et al 2014, Hale et al 2015.…”

Biochar added to soil can improve crop growth and productivity. However, the mechanisms of crop growth improvement by biochar application are not well understood, particularly in the presence of soil-borne pathogens caused by continuous monocropping. Thus, a two-year field experiment was carried out to study the chemical and microbiological response of Lixisols (pH 5.8) to the amendment of biochar and its effect on watermelon productivity and Fusarium wilt disease incidence. Biochar was added alone or together with compost before watermelon transplanting. Mixed application of biochar with compost significantly increased watermelon yield as compared to adding compost or biochar alone. However, biochar had no effects on Fusarium wilt disease incidence in both years. Combined application of biochar with compost significantly increased contents of soil NH4+-N, available phosphorus (P) and available potassium (K). Soil Biolog data indicated that the Shannon-Weaver diversity index and evenness index were increased significantly in the combined application of biochar with the compost treatment. There was a significant positive correlation between watermelon yield and soil NH4+-N, available P, available K, microbial diversity or microbial evenness in the continuous watermelon monocropping system.

“…A better knowledge of plant-biochar-microbial interactions may eventually lead to applications of biochar as a carrier of beneficial microorganisms and thus reduce the use of current carriers like peat, vermiculite or perlite (Hale et al 2015). Recently, it has been shown using P isotopes that mycorrhizae can actively mine biochar pores for (loaded) phosphorus (Hammer et al 2014).…”

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.
