Abstract:
In this work a new methodological concept of potential fertility planification and rehabilitation under irrigational
conditions. Using this method, a model of potential fertility planification was elaborated, which was verified with the
usage of lysimetres. It was determined that black earth`s fertility can be reestablished only using ecosystems` capacity
of reestablishing their own productive and reproductive potential after elimination of destructive processes, including
replacement of classical methods of investigation with using the methodology proposed in this study in the area of agro
technology. It was ascertained that in case of alienation from biological mass of plants with more than 68%, the
diminution of effective fertility of soil has a specific character: during 5-7 years, when the cultivated plants` pregnancy
diminishes achieving one particular level, after that, it remains constant despite of the fact that the intensity of alienation
process is still the same.
The results of our investigation were verified in conditions of lysimeters installed in the State Hydro meteorological
Service area.
