摘要

乌克兰农业用地土壤退化日益严重,需要改进其调查系统。首先,这与测定精度的提高和测量网格的密度有关。为了完成这些任务,涉及到新的方法,主要是地球物理方法。研究的整合和方法的合理组合具有一定的优势。近年来,利用土壤磁化率表征土壤农艺性状的研究取得了可喜的成果。本研究以哈尔科夫地区哈尔科夫地区灰化黑钙土为例,展示了综合应用多种农化方法和质量比磁化率测定的结果。我们从质谱定义的结果中发现了剔除土壤特征值的可能性。质谱与腐殖质含量之间的相关性使我们能够建议用更便宜的质谱代替更昂贵的腐殖质含量测定。土壤磁化率正确地反映了侵蚀土地的主要指标:腐殖质含量和物理粘土的空间分布。我们建议在坡地研究中使用更优的土壤质谱测量技术作为最容易获得的工具。

INTEGRATING OF GEOPHYSICAL AND AGROCHEMICAL METHODS FOR SLOPE LANDS STUDYING
The increasing of the soil degradation of agricultural lands in Ukraine requires the improvement of their survey system. First of all, it is related to the increase of the accuracy of determinations and the density of the measurement grid. To perform these tasks, new methods are involved, primarily the geophysics ones. There are certain advantages of the integration of the studies as well as development of the substantiated rational combination of methods. Recently, promising results of the application of the magnetic susceptibility of soil to characterize the agronomic properties have been obtained. This study shows the results of the integrated application of a number of agrochemical methods and determinations of mass-specific magnetic susceptibility (MS) on the example of podzolized chernozems of Kharkiv district of Kharkiv region. We identified the possibilities of culling of values of soil characteristics from the proceeding of the results of definition of MS. The nature of the correlation between MS and humus content allows us to recommend the replacement of more expensive determination of humus content with cheaper MS. Soil magnetic susceptibility correctly reflects the spatial distribution of the main indicators of eroded lands: the humus content, and physical clay. We propose the study of sloping lands with more optimal techniques of the MS measurement of the soil as the most accessible tool.
