granulometric fractions - Opis:
- Organic matter and nitrogen content was analysed in genetic horizons of Dystric Cambisols in the Kabacki Forest (Warsaw, central Poland). Particle size fractions in investigated soil indicated the following contribution in binding of organic matter: 0.1−0.02 mm – 7.6%, 0.02−0.01 mm – 13.2%, 0.01−0.005 mm – 18.8%, 0.005−0.002 mm – 21.9% and <0.002 mm – 37.8%. Sand fractions with 1−0.1 mm particles accumulate only 0.7% of the total organic matter content. Nitrogen showed similar distribution among the particular fractions. Horizons A and ABbr to the depth of 25 cm accumulate 75.8% organic matter, horizons located at the depth of 25−100 cm − 14.6%, whereas the parent rock lying at 100−125 cm on poorly permeable glacial till gathers 9,9% of the total organic matter accumulated in the entire profile. The leaching pedogenetic process and the particle size diameter significantly influenced the translocation of organic matter and nitrogen in the studied soil profile.
