Opis:
There was performed an image analysis of the structure of Ukrainian chernozem, which (I) by standard crop rotation was fertilized for 78 years with farm yard manure and (II) by continuous cultivation of sugar beet was not organically fertilized. For the both soils the largest differences were stated in the values of morphometrical parameters related to the soil solid phase element cross-sections. The differences in the parameters for pore cross-sections were much smaller. The soil I was characterized on average with larger macroporosity, larger relative and absolute number of solid phase element cross-sections, and larger relative length of border line between pore and solid phase element cross-sections than the soil II. For the both pedons the pore and solid phase element cross-sections were in general randomly oriented in the soil body. Due to the kneading the pore cross-sections in the superficial layer of the soil after monoculture of sugar beet were oriented horizontally. The soil structure in the corresponding layers of both pedons was to a high degree dissimilar. The largest differences in the arrangement of the soil solid phase and void space occurred in the upper layers.

Opis:
The objective of the study was to examine the structure of typical Ukrainian chernozem developed on loess, which (I) had been fertilized by standard crop rotation since 1912 with farm yard manure at the rate of 16 t ha-1 and (II) had not been fertilized with farm yard manure by sugar beet monoculture since 1929. After harvest of winter wheat and sugar beet, the samples of undisturbed structure were taken from 5 layers of both profiles: 0-8, 10-18, 20-28, 30-38, and 40-48 cm. The morphological analysis of the structure of the investigated chernozem revealed that the most visible differences between the soil structures of the two pedons occurred in their superficial layers. The 0-18 cm layer of the soil in the experiment I had an aggregate structure, whereas analogous layer of the soil in experiment II was much more compacted. Below about 30 cm from the ground level both pedons had very similar structure. For the soil in the experiment I an appropriate crop rotation and regular supplies of organic matter allowed for preservation of a favourable structure even in the upper layers – in contrast to the soil in the experiment II.
