    Soil magnetic properties of the landslide site in O. V. Fomin Botanical Garden
    (2023) Menshov, Oleksandr; Horoshkova, Lidiia; Kruglov, O.; Andreeva, O.
    To perform landslide susceptibility prediction, it is important to select appropriate mapping unit and landslide-related conditioning factors. Magnetic method is low cost and rapid instrument for the landslide and soil erosion identification. An example of the application of the magnetic methods for the local prediction of possible landslide activation was performed at the territory of the Alpine hill of O. V. Fomin Botanical Garden of Taras Shevchenko National university of Kyiv. The results of the soil magnetic studies demonstrated the redistribution of the soil genetic horizons. The confirmation is the visible difference from the normal natural conditions according to the magnetic susceptibility (MS, χ) values. The anthropogenic pollution was registered too. The values of MS are 1.5–2 times higher comparing with the natural chernozems of Kyiv region.

    Soil sampling and magnetic susceptibility determination in soil science: methodological aspect
    (2022) Kruglov, O.; Menshov, Oleksandr; Horoshkova, Lidiia; Tonkha, O.; Andreeva, O.; Kruhlov, Bohdan; Zhuravel, O.
    The study is dedicated to the numerous methodological problems that arise when applying the magnetic susceptibility measurements of soils for the agrarian application. The experiment was carried out for the chernozem soils of the Kharkiv and Poltava regions. Problems in the sampling planning are related to the main tillage processes. The temporal and spatial parameters as well as the sampling depth were analyzed. It has been shown that the use of soil magnetic susceptibility (MS) has a high potential in determining soil inhomogeneities. The first of all, MS is relevant in the implementation of the concept of precision agriculture, where it has market advantages over traditional methods.
