ASPECTS REGARDING THE SOIL HEALTH STATUS FOR SOME FLUVIC GLEYSOLS FROM DRAIN AREAS CĂLARAȘI FLOODPLEIN

Abstract

After draining activities, the lands present a series of specific vulnerabilities: textural heterogeneity, decrease in organic matter content, secondary salinization. These may constitute limitations in the exercise of soil functions. The study focused on an area in the Călărași Floodplain, which was formed after extensive drainage projects. Soil analyses show organic carbon reserves reduced by almost half in the first 50 cm (53%) compared to the storage potential, and organic carbon reserves of approximately 67% compared to the storage potential in the first 30 cm. Total nitrogen reserves are distributed similarly to those of organic carbon. The total salt content shows a tendency to accumulate up to the soil surface, with larger quantities below the first 30 cm. The values of bulk density and packing density, as indicators characterizing the state of soil compaction, do not highlight the existence of secondary compaction processes.
