Megjegyzések:	Solonetz soils are typical in large areas of the Great Hungarian Lowland. Our study was carried out at one of the most typical locations, Karcag. Main limitations of the clayey solonetz there are the large plasticity, swelling and low hydraulic conductivity. These conditions were intended to be improved with the chemical and hydrological reclamation and cropping of the native grassland. After 35 years soil profiles, opened in arable plots, under mostly cereal production, were compared to unimproved profiles. There were three augerings and one profile sampling through the full depth of soil profile in each of the three treatments, i) zero, that is unimproved grassland plots, ii) reclaimed cultivated plots with chemical reclamation, loosening, surface drainage, iii) drained cultivated plots with chemical reclamation, loosening, surface drainage, subsurface drainage pipes. The order of treatments represents increasing intensity and cost of reclamation. For example the salinity after 35 years is high in treatment i), decreases in ii), and lowest in iii). The same order was shown by the changes of chemical and physical properties, such as decrease of salinity and sodicity, alkalinity, field capacity and wilting point, increase of soil organic matter content and hydraulic conductivity. Soil salinity and sodicity showed significant decrease in all soil horizons (A, B, C), pF values showed significant decrease in subsurface horizons, hydraulic conductivity showed significant increase in the surface horizon. The other properties showed the mentioned tendency, but differences were not statistically significant. In spite of the extreme soil physical properties of the solonetz, the reclamation was successful. Reclaimed solonetz plots became less extreme both in terms of chemical and physical properties, which was reflected by increasing yields during the years.
