MAIN ACTIVITY OF THE LABORATORY

Soil Geoecophysics Laboratory was founded in July 1958 as a subdivision of Ukrainian Institute for Soil Science and the first head of laboratory was Peter O. Gavrik, follower of academician О.N. Sokolovskiy. Original research direction was associated with the study of the soil hydrophysics properties in the Steppe and Forest-Steppe of Ukraine for future irrigation projection. The results of the expedition and analytical works were necessary to justify the large-scale land reclamation in the country and had the support from Ministry of Irrigation and Water Resources Management.

Research of the 70-80's were aimed on the study of changes in the physical properties of the soil under influence of intensive agriculture practice and the development of practical guidelines for agriculturists. Under the guidance of Vitaly V.Medvedev (Head of the laboratory from 1973 to 1996) in simulation experiments and in working conditions were carried out relations research of soil physical properties from different methods and tools of soil tillage, from irrigation by pure and waste water, manuring and of different mineral fertilizers and industrial waste applying. The results of the long-term field experiments also were used for the model creation of optimal parameters of soil structure and bulk density within the root layer for optimal growth of various agricultural plants. Various methods for reducing of the negative impact on agricultural soil were proposed.

In the 90's of last century in the laboratory research activities was created a new direction – study of change patterns of soil properties in a continuous space. This was the reason for the name change of the laboratory to – Geoecophysics. During this period (the head of the laboratory -Tatyana M. Laktionova, 1996-2008) was selected a special polygon (27 ha), where had been investigated the patterns of spatial distribution of precipitations water and chemical elements, in connection with the physical properties of soils, relief and agricultural factors. There's also had been modeled different levels of anthropogenic stress. Similar studies were also carried out in the framework of international projects (Preferential flows and Water reuse).

In the late 90's laboratory has started active work to create database of Ukrainian soil properties, which now has over 2000 soil profiles and is a tool for estimation of soil quality in the country and separate regions. With the use of database and GIS laboratory has created a map electronic atlas of soil properties in Ukraine, has prepared several maps for the National Atlas of Ukraine, participated in the creation of the Soil Atlas of Europe (European Soil Bureau Network European Commission, 2005), as well as in several international projects, including estimation of soil degradation (SOVEUR, 1999-2001) and in the creation of the joint database of soil resources of Russia, Ukraine and Belarus (2011-2012).

In the last decade, the laboratory is actively developing a new method for soil estimation, it`s novelty is based on the account of the intrinsic linkages in the system "soil-climate-field" and on the new terms. Also the principles of pecuniary valuation of agricultural land have been developed.

 Last years a lot of attention is given studying of spatial heterogeneity of small areas. The statistical and geostatistical estimation of this phenomenon is given and gradual strengthening heterogeneity of properties of arable soil in modern conditions is established. Such researches are aimed at the decision of tasks of precision agriculture.
 In laboratory the information about new soil-protective ways of soil tillage in the world, including minimal, zero, exact, conservative and others is collected. Suitability Ukrainian soil for introduction of different ways of tillage is estimated.

The information on needs of different plants concerning soil and climatic parameters is collected. These materials are used for a various zoning, estimation, determination of investment appeal of the plots, suitability for cultivation of different plants.
