摘要：

Chestnut Brown soils of western Transbaikalia exhibit various regional peculiarities in the distribution of humus and nitrogen over their particle-size fractions. Clay particles play an important role in the deposition of these substances. Agricultural utilization is shown to affect the humus and nitrogen concentrations in the various particle-size fractions.
