  • The program for the mining of Transdanubian brown coal measures will probably influence the water recharge and thus the water supply of the area. (C. Kiricsi).

  • A survey of soil fund structure in the CSR for the height soil zones of hydromorphic soils, chernozems, brown soils, illimeric podzol soils, brown forest soils and mountain podzol soils. (MS).

  • The soils of the area consist of the podzols, rankers, rendzinas (alpine subtypes), pseudogleys and brown soils. The vertical soil zonality in the crystalline and mezozoian oart is presented as well. (MS).
  • 1981
  • The forest soils developed in the sandy weathering material of the Liassic limy sandstones in southeastern Belgium have been mapped as argillic brown sands ore, more rarely, as podzolic soils. Chemical and mineralogical analyses make the author

  • ) correspond approximately to the medium contents in soils predominantly used for agricultural purposes. Brown earths over olivine-nephelinite, gneiss, and phyllite are richer in trace elements than podzols over quartz porphyry. But even in the case of brown

  • frost and thaw cycles, include frost cracks, cryoturbations and creep or solifluction mass movements. Fossil soils are either gray brown podzolic soils developed under forest, or hummic steppic soils.

  • Red-brown and meadow-gley soils of the dry regions are potentially very fertile. Rice cultivation does not induce visible changes in the mineral part of the soils. Soils on interstream areas and those in the lower parts of the slopes are shown
  • 1981
  • Climatic and pedoclimatic features of the areas of European sod-podzolic, lessivé and brown forest soils are compared. The differences in quantitative pedoclimatic indices, the thermic ones especially, proved to be neteworthy. They account
