| Popis: | Three variants of model soil constructions were created. Variant 1 (control) is made from Aarable horizon (0-18cm); variant 2 (layered construction) is represented by Aarable horizon (0-6cm), lowland peat (6-12cm), sand (12-18cm); variant 3 is a mixture of Aarable horizon, peat and sand in the same mass proportion as in the layered variant (0-18cm). Water retention capacity of Aarable horizon increased in all variants regardless of the location in the profile. Number of macropores increased and number of mezopores decreased in Aarable horizon of control and layered variants. The greatest number of moisture-saiving pores is observed in the peat-containing layers of variants 2 and 3 as a result of 4-year functioning. The lowest content is in the control in all layers. |
