Wpływ zróżnicowanych zabiegów uprawowych wykonanych po siewie zboża jarego na właściwości fizyczne gleby

Abstract

The research aimed at determining changes in the values of selected soil physical properties influenced by the treatments operations carried out after spring cereal sowing. In a three-year experiment, the following soil physical properties were determined: soil consistency, dry soil density, soil humidity and capillary porosity. The determination was repeated at two dates (I – at the stage of plant germination; II – at the stage of cereal maturity). Conventional methods were employed. As a result of post-sowing rolling, the values of the studied soil properties increased. The highest values followed from the application of heavy meadow roller. The magnitude of changes depended on soil humidity, the length of the period between application of treatments and the plant development stage. Under the conditions of lower soil humidity and at the end of cereal growing season, the differences in the values of physical properties between treatments decreased markedly.
