Study on the humus in brown forest soils under different vegetations


Acta Pedologica Sinica 24(1): 27-34
Study on the humus in brown forest soils under different vegetations
Investigation on the composition and characteristics of humic substances in brown forest soils under three different vegetations was made. The results showed that the highest content of humus was found in the soil under pure forest of Betula albo-sinensis Burk, the highest content of humic acid and HA/FA ratio were in the soil under pure forest of Quetcus liaotungensis Koidz; the contents of active humic acid in the soils under all the three forest vegetations were higher, but the highest content was in the soil under the pure forest of Betula albo-sinensis Burk. Data of optical densities, floculation limits and from infra red spectrophotometric and X-ray diffraction analyses showed that aromaticity of humic acid in brown forest soils under different vegetations was decreasing in the following order: that in soil under forest of Quercus liaotungensis Koidz > that in soil under forest of Betula albo-sinensis Burk > that in soil under secondary forest of Pinus tabulaeformis Carr.
