DISTRIBUTION OF HUMIC FRACTION IN REPRESENTATIVE SOILS FROM GURGHIU MOUNTAINS
The analysis of organic matter components was perfomed for 4 soil subtypes, which were identified and diagnosed in Gurghiu Mountains: one andic, histic Districambosol (830 m altitude), one cambic Andosol (1200 m altitude), one cambic-histic Andosol (1495 m altitude) and one typic Prepodzol (1725 m a...

| description | The analysis of organic matter components was perfomed for 4 soil subtypes, which were identified and diagnosed in Gurghiu Mountains: one andic, histic Districambosol (830 m altitude), one cambic Andosol (1200 m altitude), one cambic-histic Andosol (1495 m altitude) and one typic Prepodzol (1725 m altitude). The research aimed to identify qualitative and quatitative differences in organic matter. The results show that the organic matter accumulation is high and it correlates with soil subtype, altitude and vegetation. The cambic Andosol presents high organic matter contents throughout the profile. The highest degree of humification characterizes the typic Prepodzol, while the other analysed soils present lower and comparable values. The polymerization degree of humic acids shows the dominant formation of fulvic acids, excepting the cambic-histic Andosol, in which case the ratio between the two types of acids is close to one. |
