Changes in chemical properties, mineralogical composition and microstructure of the taiga surface-gley forest and cultivated soils were studied. The cultivated soil was previously drained, limed and manured. Different dozes of NPK were applied during 5 and 20 years. Perennial grasses were grown on the plots studied. Long - term application of small dozes of NPK (40 - 100 kg ha⁻¹) contributed to a biological transformation of arable horizons and formed a high quantity of biogenic pores and aggregates. Improvement of water permeability and drainage caused removal of the organo-mineral compounds from the upper horizons. These compounds were accumulated near drains. In our experiments, optimal dozes of NPK applied to form biogenic aggregates were N120 P120 K120 and N240 P240 K240. The higher dozes of NPK caused an increase in both the humus and iron removal and destruction of aggregates. Mineralogical composition was determined by the X-ray and immersion methods in fractions: >0.01, 0.01 - 0.001. and <0.001 mm. The higher and non-balanced dozes of NPK contributed to the changes in minerals containing the biophilic elements (micas, chlorites, amphiboles) in the coarse-textured fractions of soils. The fertilizer’s potassium was fixed by labile clay minerals and transformed to a weakly available form for plants. Dozes of N120 P120 K120 were optimal. These dozes did not cause noticeable changes in minerals, but resulted in significant grass yield.

Zbadano zmiany właściwości chemicznych, składu mineralogicznego i mikrostruktury leśnej i uprawnej gleby glejowej tajgi. Stwierdzono, że zmiana użytkowania gleby z leśnej w uprawną z zastosowaniem drenażu, wapnowania, obornika i nawożenia mineralnego NPK spowodowała istotne zmiany we właściwościach glejowej gleby tajgi o ciężkim składzie mechanicznym. Zmiany te dotyczyły zarówno masy glebowej, jak i procesów glebotwórczych.
