“…Values of χ FD > 10% indicate a large contribution of SP particles. The scattergram shows that the largest contribution to magnetic susceptibility is due to SP ferromagnetic grains <0.05 µm (Kanu et al, 2014).…”

“…Low-field magnetic susceptibility is the most commonly used magnetic parameter due to its fast acquisition and successful application as qualitative proxy for pollution agents in a large number of studies (e.g., Hoffmann et al, 1999;Hanesch and Scholger, 2002;Boyko et al, 2004;Magiera et al, 2006;Hanesch et al, 2007;Kanu et al, 2014). It is assumed that increased χ values correlate with increased amounts of heavy metals due to their http://dx.doi.org/10.18268/BSGM2018v72n1a111219…”

“…The carbonate mass percentage was determined by measuring the volume of CO 2 produced by each sample's chemical reaction with 10% hydrochloric acid (Ministry of Agriculture of China, 1993). A Magnetic Susceptibility Meter (England Bartington MS2B) was used to obtain information on both high and low-frequency susceptibility [38,39]. Soil porosity can be obtained through the following method [40].…”

To determine the permeability characteristics and the groundwater enrichment conditions of loess and paleosol layers, this article systematically investigated the permeability, magnetic susceptibility, porosity, and carbonate mass percentage of representative loess-paleosol layers (L1 to S5) on the Bailu tableland in the Chinese Loess Plateau south. The result of in situ permeability measurements showed that the average time to reach quasi-steady infiltration of loess layers is shorter than that of paleosol layers. In addition, loess layers have higher porosity and better water storage spaces than paleosol layers and were prone to form aquifers. Paleosol layers, on the contrary, are more likely to form aquitards. The difference between loess and paleosol in permeability, porosity and groundwater enrichment conditions is largely attributed to lower intensity pedogenesis of loess, which is in turn ascribed to the colder and drier palaeoclimatic conditions. It is worth mentioning that the CaCO3 concretion layer is a good aquifuge for its compact structure. Generally, the empirical formula of the Koctakob formula is applicable for describing the permeability rule of loess and paleosol layers, and the parameters of the empirical formulas can provide an important reference for hydrological and agricultural departments. In this regard, the Quaternary climatic change theory can contribute to the hydrogeology of the Chinese Loess Plateau, and the regional climatostratigraphy can be regarded as a baseline for local water resource positioning and revegetation in such a semi-arid area, which broadens the application field of Quaternary climatic change theory. Meanwhile, it also provides a reference path for solving water shortages of other loess distribution areas in China and other countries.

“…The difference in susceptibility was proven to be highly sensitive on the change of magnetic mineral grain size, magnetic mineral morphology, as well as the type of magnetic mineral. Therefore, the measurement of magnetic susceptibility on a specific sample can be used as the indicator of change in type and morphology of magnetic minerals due to the environmental change (Kanu et al, 2014). Experimentally, the correlation between the size of magnetic mineral and magnetic susceptibility in the magnetic mineral with magnetite (Fe3O4) type has been proven.…”

The measurement of magnetic susceptibility, pH, element concentration of Fe and apples diameter has been conducted in orchard soil of Malang, East Java Indonesia. The measurement was performed in two orchards, namely Pujon and Poncokusumo with two different kind of apples in each orchard. This research aimed at exploring in detail linked between magnetic properties, the existence of magnetic mineral as magnetic property carrier in the soil, soil pH, as well as the size of apple diameter to evaluate the quality of apple production in the both areas. The results shows that the soil with lower susceptibility, it was expected that the magnetic mineral of magnetic property carrier to be smaller, low soil pH, meaning that the soil was more acidic which implied on a larger size of apple diameter for Rumbeauty type of apple. Meanwhile, when the soil had a higher susceptibility, and it is expected that the magnetic mineral is also high as well as having high pH, this growing media is appropriate to develop Manalagi type of apple. Based on the observed soil magnetic properties and pH from both observed orchards, it can be suggested that Manalagi apple is appropriate to be planted in Poncokusumo area, while Rumbeauty is appropriate to grow in Pujon area.
