The indices of soil quality have been studied in Volgograd oblast, and the reasons for the worsening quality have been identified for different groups of soils. It is suggested that information on the genetic diversity of soils, their properties, and the character of soil management should be specially collected and systematized in order to make strategic decisions aimed at soil conservation. Information should be separately collected for the soils of agricultural lands, the soils of specially protected natural territories (including the soils listed in the Red Data Book of Russian Soils), and the soils that are used for nonagricultural purposes. 相似文献
