^* JIS A 1226 (Japanese Standards Association, 2009) is available for its definition

^† The Von Post scale is a visual classification system used to assess the degree of peat decomposition, consisting of ten classes from H1 to H10, where H1 represents the least decomposed peat and H10 represents the most decomposed (Rezanezhad et al., 2016)

^‡The values are determined from N-, K- and T- IL-3, respectively, under 24°C, and can vary depending on the strain rate and temperature. The temperature is 24°C and the strain rates taken here are in order of 10⁻⁷ to 10⁻⁸ (/s)
