In contrast to xylose, the larger proportion of soil arabinose than that of herbaceous plant materials may be attributed in part to difference of decomposability
between these pentoses of plant materials. During the second stage after the flush of
decomposition in a 36 months agricultural field experiment, arabinose of two
herbaceous species, paddy rice and barley straw were decomposed by a slower
rate than xylose (Murayama 1984a). For instance, 27% of arabinose in rice straw
was decomposed by half-life time of 36.6 month, in contrasting to 19.6 month of
22% of xylose of the same rice straw.
Fig. 6.3 Monosaccharide composition of soil under different land use and soil parent materials.
EH-glucose easily hydrolysable glucose, NEH-glucose non-easily hydrolysable glucose. (1) Arable
soil developed from prairie or grass land (non-volcanic ash, n ¼ 3); (Oades et al. 1970; Oades and
Wagner 1971). (2) Arable soil developed from non-forest (non-volcanic ash, n ¼ 5) (Murayama
1980, 1985). (3) Arable soil developed from sand dune, n ¼ 2 (Murayama 1985). (4) Arable soil
developed from forest (volcanic ash, n ¼ 6) (Murayama 1980, 1985). (5) Forest soil (volcanic ash,
n ¼ 3) (Murayama 1980; Sugiura et al. 2017). Statistical test: (1) The same Greek letter symbol
means there is no significant difference among five soil groups. NEH-glucose, mannose, arabinose,
and xylose have the same symbol pattern to EH-glucose. Galactose, ribose, and rhamnose have no
significant difference among soil groups. (2) Average proportion of monosaccharide of three groups
of non-forest soil; EH-glucose > NEH-glucose ’ xylose > arabinose > mannose ’ galactose >
rhamnose > fucose > ribose (’means no significant difference). (3) Average proportion of
monosaccharide of two groups of forest soil and forest-derived arable soil: EH-glucose > mannose
> galactose > xylose > arabinose > NEH-glucose > rhamnose ’ fucose > ribose
