Физические свойства выщелоченных черноземов Северного Зауралья в условиях длительного сельскохозяйственного использования

Физические свойства выщелоченных черноземов Северного Зауралья в условиях длительного сельскохозяйственного использования

Abstract

The agricultural use of the leached chernozems leads down the forming to depth 3040 and 70-80 cm of the overdense layers 1,40 and 1,65 g/cm 3 respectively. The porosity of aeration in the layer 30-40 cm with the humidity of the corresponding field water capacity is reduced to 6%, which can lead down the forming of surface root system. Sowing perennial grasses restores the physical indices of soil to the level of the virgin soil.

Сельскохозяйственное использование выщелоченных черноземов приводит к формированию на глубине 30-40 и 70-80 см переуплотненных слоев 1,40 и 1,65 г/см 3 соответственно. Порозность аэрации в слое 3040 см при влажности, соответствующей наименьшей влагоемкости, снижается до 6%, что может привести к формированию поверхностной корневой системы. Посев многолетних трав восстанавливает физические показатели почвы до уровня целины.
