| Popis: | Chemical and microbial characterizations were carried out for forty-four compost products, whose raw materials were classified into seven categories: wood, coffee ground, grass, buckwheat shells, animal manure, food waste, and others. Microbial community structure in the composts was examined by quinone profile analysis. Values of the chemical and microbial properties varied considerably as follows: moisture content 3.1–82.7%, pH 4.38–9.44, electric conductivity (EC) 0.12–17.08 mS cm−1, total carbon (TC) content 16.9–51.0%, total nitrogen (TN) content 0.61–9.83%, C / N ratio 5.2–53.1, ash content 4.2–63.2%, total quinone (TQ) content 0.0–215.2 µmol kg−1 dry sample, and value of quinone diversity (DQ) index 0.0–20.8. The wide range in the values expressed the diversity of the chemical and microbial properties of various compost products. The chemical properties were related to the raw materials while the microbial properties tended to be less related. Total menaquinone contents were higher than th... |
