С. 108-115.УДК 631.472.6(41/42)https://ir.library.knu.ua/handle/15071834/9372Викладено результати досліджень підзолисто-дернових поверхнево-оглеєних грунтів північно-західного Передкарпаття. Схарактеризовано морфологічні особливості, фізичні та фізико-хімічні властивості ґрунтів, проаналізовано зміни, викликані сільськогосподарським використанням. Встановлено, що тривалий антропогенний пресинг на ґрунти спричинив розвиток деградаційних процесів.Podzolic-sod surface-gleyed soils (Albeluvisols Gleyic (ABgl), Umbrisols Gleyic (UMgl) are modal for the territory of Northern-Western Subcarpathia occupying an area of 21,800 hectares. These soils are mainly used for arable land, gardens, hayfields and pastures. Long-terms agricultural use significantly influenced soil regimes and processes, physical and physical-chemical properties of soils, their agro-ecological status. The object of the research is podzolic-sod surface-gleyed soils on deluvial sediments. The subject of the research is morphological features, physical and physical-chemical properties of soils and their transformation under the influence of agricultural use. Podzolic-sod surface-gleyed soils are characterized by a developed humus profile. The depth of the humus horizon of the A non-eroded type is 28-36 cm on average. There are signs of gleying in the form of iron-manganese punctation and ochreous spots from the surface. Soils have peculiar medium-grained granulometric composition, the content of physical clay is 30.09-30.30%. Soils have undergone repacking and loss of structure. The density of the structure in the arable layer is 1.40-1.46 g/cm3, and the content of agronomically valuable meso-aggregates (0.25-10.0 mm) is 36.80%. The structural and aggregate state of soils is characterized as unsatisfactory. The content of humus in the arable horizon of A podzolic-sod surface-gleyed soils is 2.05%. In the soils that have undergone erosion degradation, the humus content is much lower, in the arable layer (0-30 cm) of the slightly washed-off types it is 1.65%, in the moderately washed-off types – 1.37%, and in the heavily washed-off types – 1.06%. According to the accepted gradations, the humus content is assessed as low and negligibly insignificant. Soils are characterized by a neutral and slightly acidic reaction. рНКСІ in the arable horizon is 5.48-6.36. Podzolic-sod surface-gleyed soils undergo degradation caused by active anthropogenic pressing, in particular, water erosion, overburdening, decomposition, dehumidification. The agro-ecological state of the soils is mostly evaluated as complex and unsatisfactory.ukпідзолисто-дернові поверхнево-оглеєні ґрунтигранулометричний складгумусерозіядеградаціяохорона ґрунтівpodzolic-sod surface-gleyed soilsgranulometric compositionhumuserosiondegradationsoil protectionСтаття
