An integrated approach to the study of the hydrophysical properties of soil structures in the agrolandscape of a reclaimed landfill

Abstract

An integrated approach to the study of the hydrophysical properties of soil structures, newly created agrolandscapes of a recultivated landfill, makes it possible to determine the regularities of the moisture regime. The object of the study is a section of the municipal solid waste landfill in the city of Barnaul, located in the northwestern part, where reclamation has been carried out. Works were carried out on the selected site: leveling and leveling, screening with clay layers and new soil structures were formed: soil (606 t/ha), a mixture of soil and sewage sludge (303 t/ha + 303 t/ha), sewage sludge (606 t/ha). Festulolium seeds were sown. The variant of the mixture of soil and sewage sludge according to the obtained indicators is the most optimal variant in terms of water-holding capacity and the ability to transfer this moisture to plants. The use of sewage sludge for landfill reclamation and the creation of an agricultural landscape had a significant impact on the hydrophysical properties of soil structures.
