SOIL OLD AGE

The old and stable landscapes reach a balance with the environmental conditions and have a special beauty, acquired during their long process of formation. Likewise, the very old soils have a special beauty and a unique development of the pedogenetic horizons. This beauty and uniqueness highlighted the paper, by the aim of the researches of an Alosol (SRTS-2012; Alisol - WRB-SR-2014) located on an old and stable terrace relief, researches that starting from the morphological level and reaching the more detailed level of micromorphology. The Alosol had, at least in its upper part, the appearance of a Dystricambosol, due to the high acidity and the destruction processes that penetrated deep into the Bt horizon. The main characteristics that emphasised the oldness of the studied Alosol were the: depleted, textural, and amorphous pedofeatures (whose composition, colour and location reflect their age). The most spectacular was the network (with perfect angles at 90 degrees and greenish-gray reduction colours) expressed more clearly in the Bt2W horizon. The melioration of such an old soil should be very expensive, the reforestation being the most suitable.
