This study evaluated the effects of biochar from the pyrolysis pine on the soil microbial communities by fatty acid methyl ester (FAME) in upland field. The nutrient management for lettuce cultivation at silt loam soil was treated with four rates of biochar 0 (CFB1), 60 (CFB2), 120 (CFB3), and 240 kg 10a<SUP>-1</SUP> (CFB4) with chemical fertilizer (14.3 kg 10a<SUP>-1</SUP> N, 15.7 kg 10a<SUP>-1</SUP> P₂O<SUB>5</SUB>, and 12.1 kg 10a-1 K₂O), no fertilizer (NF), and pig manure compost 2 ton 10a-1 with chemical fertilizer (CFC). Compared to the NF, the soil microbial biomass (total FAMEs), Gram-negative bacteria biomass, arbuscular mycorrhizal fungi (AMF) biomass, and total glomalin concentration were significantly increased after biochar amendments treatment, while the microbial biomasses were not significant between CFB1 and biochar treatments. CFB3 and CFB4 had a significantly lower ratio of cy19:0 to 18:1ω7c when compared with that of CFC (P < 0.05), which indicates that a decrease in microbial stress was caused by organic matter soil inputs without competition from other microbes. Community of actinomycetes in CFC soil was significantly larger than those in biochar treatment soils (P < 0.05) indicating actinomycetes are potentially responsible for the microbial community differentiation between CFC and biochar treatments in upland field.
