Plant and Soil Science

The research was conducted on the pilot field of land reclamation of the Dnipropetrovsk State Agrarian and Economic University. The indexes of humidity of steady wilting of plants in pedosomes by the calculated method and vegetation miniature method are determined. The results of the research for pedosomes indicate that the data obtained using the calculation method and vegetative thumbnail method differ significantly from each other. The reasons for the discrepancies of these approaches are established. More variables are the values obtained when tested with vegetative miniatures. It was found out that for pedosens, the moisture content of persistent plant wilting is 7.87-11.93%. For the type of techno-type studied, the uniform distribution of this indicator by the profile is characteristic. Only in the middle of the profile there is an increase in the humidity of plant wilting to 11,93%. Such peculiarities of the accumulation of technosomes can be considered as negative for the growth of plants and the formation of the productivity of ecosystems. According to the results of regression analysis, it has been proved that the soil's salinity has the greatest influence on the moisture content of stable plant wilting. The constructed pedotransfer functions make it possible to reduce the loss of labor during the determination of this hydrological constant and obtain an indicator that has obvious ecological significance.
