Soil-geographical research of the North-West Black Sea region

Annotation

In  the  dissertation  there  is  theoretical  generalization  of  the  soil  and  geographical
research development in the North-West Black Sea region given. It was ascertained that
existing works do not cover to the full extent the evolution of scientific views, theories and
hypotheses about the genesis, geography, structure, soils properties and their efficient use,
as  well  as  that  they  are  not  arranged  enough  as  to  soil  science  research  formation  and
development in the given region.
There  were  natural,  personal,  social  and  political  premises  observed  that  largely
determine nature and direction of scientific research.
There  was  periodization  of  the  soil  and  geographical  research  development  in  the
North-West  Black  Sea  region  suggested  and  proved.  The  lack  of  references  makes  it
impossible to recreate a holistic development of agriculture and study of the topsoil before
the beginning of the XVIII century, but accumulated data allows to affirm that there is
gradual accumulation of empirical knowledge about soil properties, especially their use in
agriculture, methods of cultivation and so on. Intensive development of the North-West
Black sea region started in XVIII century and caused the necessity of topsoil research. For
the first time there were suggested soil genesis hypotheses that gave priority to the single
causes  of  soil  formation:  biological  connection  with  rocks  (I.  Hebenshtreyt,
M. Lomonosov, M. Afonin, I. Komov, A. Bolotov, I. Gyuldenshtedt, M. Livanov), source
rocks,  climate  (A.  Hrossul-Tolstoy),  relief  and  its  connection  with  other  nature
components (O. Schmidt) etc.
Equivalent and interdependent connection between single causes: climate, flora, soil
formation  rocks,  relief  of  the  territory  and  time,  was  proved  by  V. Dokuchaev.  The
scientist  divided  the  region  into  districts  and  marked  out  the  Norh-West  part  of  the
chernozem zone in Russia and the North coast of the Black Sea, that strongly differ in the
chemical and mineralogical structure of soil and rocks, kind of flora, relief of the territory
and climate conditions. As the result of the research factor and genetic soil classification
was  developed,  and  its  base  was  soil  genesis. Agreeing  with  the  general  soil  spreading
layout,  suggested  on  the  maps  of    K.  Veselovs’kiy  (1851),  A.  Hrossul-Tolstoy  (1856),
F. Ruprekht (1864 r.), R. Vilson (1869 ) and V. Chaslavskiy (1879) V.  Dokuchayev made
up the soils map of the chernozem zone of Russia European part. Output data was not only
descriptive and statistic, but also data of analytical studies with the use of isohumus strips
method.
The role of Odesa «South»` school was examined in its soil research of the North-
West Black Sea region. Various studies of O. Nabokykh, G. Tanfilyev, O. Piotrovskohiy,
G. Makhov assisted in formation of scientific schools of soil science. Scientists developed
theoretical  and  methodological  base  of  the  topsoil  study,  suggested  physical  and
geographical division into districts of the territory with zonal and intrazonal differences,
carried out soils agrochemical  inventory,  made up non-uniformly scaled soils maps and
established the first Soil museum.
Scientific  works  of  O.  Sokolovskyy  had  essential  meaning  for  the  soils  research
development  both  of  Ukraine  as  a  whole  and  of  the  North-West  Black  sea  region  in
particular. Under his guidance new areas of soil research were initiated, aimed at studying
of  properties  and  possibilities  of  halogen  soil  use  in  the  South  of  Ukraine;  new  soils
classification was developed, that met the criteria of genesis, unity of soil formation and
exhaustion.
It  was  found  out  that  boundary  between  separate  topsoil  research  and  purposeful
intensive research on the governmental level was large studies (1957-1961).
Wide development of irrigation in the second half of the XX century led to the chain
of  negative  consequences  that  caused  the  necessity  of  deeper  studies  of  the  irrigation
influence on the irrigated lands soil and reclamation situation. Work of the scientific and
research  institutions  and  organizations  was  analyzed  as  to  agriculture  ecological  and
reclamation  problems  in  the  area  of  irrigation  systems,  changes  of  soils  physical  and
chemical characteristics under the influence of  years of irrigation, irrigation water quality,
features of the certain crops cultivation and etc.
The  meaning  of  I.  Gogolev  research  in  the  soil  and  reclamation  area  development
was determined. Also there was made the analysis of the geochemical and landscape, soil
and  mapping,  morphogenetic,  soil  and  environmental  trends  and  monitoring  studies,
conducted under the direction of Professor I. Gogolev, and soil and erosion direction, led
by Professor G. Shvebs.
The current stage is characterized by a weakening of experimental and expeditionary
studies, due to the practical absence of state funding and low logistics. There were defined
current areas of soils research, their scientific issues and key achievements of scientists in
soil research since Ukraine has been independent.
Keywords:  soil  and  geographical  research,  the  North-West  Black  Sea  region,
directions of soil science research.
