Improvement of physical and chemical properties of Hungarian sandy soils by adding organic and inorganic amendments

摘要

The main purpose of the study was to investigate and compare the single and precomposted combined effects of different amount of organic (liquid manure, sewage sludge) and inorganic (bentonite, montmorillonite, CaCO_3) treatments on soil physical, chemical properties of sandy soils from Nyirseg geographical area. Laboratory and field experiments were carried out for the study. The laboratory samples included sandy soil treated with increased amount of montmorillonite and bentonite; liquid manure; beet potash and the precomposted combinations of those. Sewage sludge compost was applied on the field. Rheological methods were applied to detect the changes in physical properties of soil samples.
