centrului de grupare. De remarcat valorile apropiate ale acestor indicatori.Carbonaţii din solurile zonelor analizate sunt, predominant, de natur ă geogenă. Numai în
solurile urbane se poate vorbi şi de o oarecare participare a factorilor antropici la acumularea decarbonaţi şi numai în prima jumătate a profilului de sol. Eroziunea poate constitui un alt factor, înmediul rural, care să contribuie la ridicarea concentraţiei carbonaţilor în orizonturile de suprafaţă.

these indicators.Carbonates from the soils of the investigated ar eas are predominantly geogenic. Only in urban
soils do anthropic factors contribute to carbonate accumulation and only within the first half of the soil profile. Erosion may constitute another factor in the rural area, which would contribute to the increasein carbonate concentration within the upper horizons.
