    ESTIMAREA CANTITATIVĂ A PIERDERILOR MEDII ANUALE DE SOL PE DIFERITE CATEGORII DE UTILIZARE A TERENURILOR. STUDIU DE CAZ: BAZINUL HIDROGRAFIC TIGHECI

    The scientifc results obtained from the research in the Tigheci hydrographic basin (located in the northwest of the Tigheci Hills) argue the immense agricultural potential of the region, but the erosion processes lead to a reduction in the amount of humus and nutrients in the soil, thus limiting the ability to productivity. erosion is the most widespread geomorphological process, has an appreciable intensity especially on the agriculture lands, where the average rate of soil loss, estimated according to the ROMseM model, is 2.16 t/ha/ year. although erosion is seen as a bio-physical process, the way of land use contributes signifcantly to the appearance of this form of degradation, having numerous economic consequences. Thus, it was found that the soil loss values are higher on arable land (about 11 thousand ha affected), followed by pastures (over 2 thousand ha) and perennial plantations (about 1000 ha). The need for such a study in order to estimate soil losses is of great importance, because only by quantifying the risk can differently measures, ways to prevent and combat erosion processes be developed.

    ISTORICUL CERCETĂRILOR PEDOLOGICE ÎN CADRUL BAZINULUI HIDROGRAFIC CUBOLTA
    (CEP USM, 2024) Curcubăt, Stela; Ciolacu, Tatiana; Canţîr, Angela
    This article presents the analysis and synthesis of pedological research results on the soils of the Cubolta watershed. The history of soil research in the Prut-Dniester region dates back to 1868, and the soils of the Cubolta watershed have been elucidated on soil maps numerous times up to the present day. The pedogeographical conditions in this territory have contributed to the formation of a very rich soil cover over time. From the analyzed bibliographic sources and the results of pedological research, it is concluded that the land surface comprises taxonomic units from all five soil classes and consists of 24 soil varieties, of which 63.4% are chernozems. Analysis of the bibliographic data confirms the destructive processes affecting the soils in the studied area, including erosion, landslides, dehumification, salinization, and solonization. Soil degradation in the watershed is a consequence of their incorporation into agricultural practices without the use of appropriate agricultural machinery and land protection methods and land improvement.
