AGGRFGATE STRUCTURE OF INDUSTRIAL SOILS OF THE NIKOPOL
MANGANESE ORE BASIN
1Dnipropetrovsk State Agrarian University
2Oles Gonchar Dnipropetrovsk National University
The profile distribution of industrial
aggregate structure in the experimental
polygon of the Nikopol manganese ore basin has been studied. The soil type and layer depth
were the most powerful factors of formation of aggregate structure of industrial soils. The
distinctive abilities of aggregate structure dynamics for differentiation of industrial soil type
according to their profiles have been defined. The variability of indices of fractions between
10 and 0.25 mm was depended on the industrial soil type and to a lesser degree from the
profile allocation. Percentage of structural aggregates with a size 3-1 and 1-0,5 mm were
typical for certain levels of a profile also is similar in different industrial soils. There was
certain specificity of profile allocation of fractions with a size 10-7 and 7-5 mm, distinguishing
industrial soil type from each other.
Keywords: aggregate structure, industrial soils, recultivation.
