It consists of alpine meadow grassland types with grassy weeds as vegetation and meadow soils
. Three plots were located between a hill and a river, and each plot has different distances to the hill and river (Table II), the plots had a different soil structure and vegetation composition.
Comparative analysis of alas meadow soils
of alases Lena-Amga and Lena-Vilyuy River interfluves showed that the most optimal conditions for earthworms functioning develop in meadow soils
of alases of Tiung and Tiukyan rivers' interflude.
Comparison of carbon contents in meadow soils
shows that the total carbon content is higher in the lower point of relief of the plot concerned.
Assuming that montane meadows are less productive than lowland prairies and grasslands, our results suggest that mound soils, originating from deeper horizons, are less fertile than adjacent meadow soils
, consistent with a pattern of lower root productivity and soil organic matter at depth (e.g., Dodd et al., 2000).
Other plants for our typical meadow soils
include most astilbes.
Northern chrenozems mixed with meadow soils
and small areas of saline soils cover about 1 million ha (2.5 million acres) of land in an area where precipitation and evaporation are approximately equal.
The only previous dust and soil data collected (Walker and Costin 1971) suggested that the accession of aeolian dust across the mountainous areas of south-eastern Australia has been a significant factor in the development of alpine soils, in particular, snow patch meadow soils
. Walker and Costin (1971) found that the clay content ([is less than] 0.002 mm) of these soils had several origins, such as current chemical weathering, weathering prior to periglaciation, the decomposition of the deep-rooted alpine/subalpine vegetation to produce colloid-sized sesquioxides at the soil surface, and dusts (resembling parna) blown in from the semi-arid and arid zones of Australia (Costin et al.
When taken together, the [K.sub.d] indices for N[H.sub.[4.sup.+]] and amino acids in the alpine dry meadow soils
reflect an important role for the soil in adsorbing and retaining nitrogen compounds.
Influence of ant hills on the meadow soils

Dry and moist meadow soils
are primarily Cryumbrepts, while wet meadow soils
have been classified as Cryaquepts (Burns 1980).
The contribution of [P.sub.0] to total P ranged from 33% in anaerobic bog soils to [less than] 1% in the aerobic swamp and beaver meadow soils
. The aerobic: anaerobic [P.sub.0] ratio was lower in more minerotrophic sites (0.61-0.89 in bogs and fens, 0.060.26 in beaver meadows and swamps).
(1994) reported that dry meadow soils
of alpine tundra contain substantial carbon concentrations, perhaps the highest of any aerobic soils found in temperate zones.
