Significant differences between WP and DP soils were found in gypsum, carbonate contents, available water holding capacity and infiltration rate.
Significant differences (p ≤ 0.05) between the EXO and NAT soils were found for soil chemical properties.
Strong correlations between the infiltration index and both soil compaction and the water holding capacity of soils were found.
As expected, soils were found to be colder below deep moss mats as described by a significant negative regression between soil temperature and moss depth (R = 0.22, F1,20 = 6.90, P < 0.05).
A belt of solonetzic and planosolic soils is found between these two soil types.
Even assuming that multiple microbial species can share the same TRFLP peak size, this high degree of sharing of TRFLP peaks between plants grown on different soils was found to be statistically non-random and highly robust across Z. mays genotypes (Additional file 6: Table S3).
A logarithmic relation between chargeabilities and smoothed hydrocarbon concentrations in soils was found.
North of this region, lower-quality black soil and gray wooded soils are found.
Many types of soils are found throughout the country.
Gray-brown podzolic (leached) soils are found at higher elevations.
