Документ INTRODUCTION OF THE GEPIC MODEL TO OPTIMIZE LAND-USE IN ODESSA REGION(Печатний дом, 2011) Lebediev, D. G.; Korzun, T. V.; Gazyetov, Ye. I.; Medinets, V. I.At present, under conditions of climate changes and such anthropogenic factors as irrigation and application of fertilizers to soil, modelling of spatial and temporal dynamics of the main processes in the system soil-plants-atmosphere-agriculture acquires essential importance in order to forecast socioeconomic development of the country and efficient use natural resources, in particular - land.Документ SOIL GHG (N2O/CH4) EMISSIONS IN THE FERTILISED ARABLE LAND(Печатний дом, 2011) Medinets, S.; Skiba, U.; Kotogura, S.; Medinets, V. I.; Drewer, J.; Pitsyk, Vasyl Z.; Пицык, Василий Зиновьевич; Піцик, Василь ЗіновійовичSoil/atmosphere fluxes of N20 and CH4 were monitored for a 16 months period at the arable site "Petrodolinskoye", located on southern Chernozem black soil, using three SIGMA (System for Inert Gas Monitoring by Accumulation) autochambers - lowcost techniques for sampling cumulative gases over long time periods. These systems were constructed for the NitroEurope IP (017841) purposes. Chambers (0.3*1.5 m2) were located 71 m equidistantly in the centre of a 30 ha field. Fluxes were measured 3 times per day by collecting gas samples into FlexFoil bags.Документ Study of role of nitrogen use efficiency for restoration of arable land area(2011) Medinets, S.; Medinets, V. I.; Bilanchyn, Yaroslav M.; Kotogura, S. S.; Pitsyk, Vasyl Z.; Rezvaya, S.; Медінець, Сергій Володимирович; Медінець, Володимир Іванович; Біланчин, Ярослав Михайлович; Котогура, С.

С.; Пицык, Василий Зиновьевич; Резвая, СветланаThis study shows an estimation of Nitrogen (N) budget and N use efficiency in arable land area, located on typical Chernozem soils in Southern Ukraine. These Chernozem black soils (CH vec) have been farmed for more than 200 years and in many years between 85-90 % of these soils are ploughed. Crop rotation with fertilisation (2007 - 2010) and irrigation (2007 - 2008) was used on investigated area.Документ USE OF GIS TO QUANTIFY THE LONG-TERM CHANGES IN NATURAL OBJECTS(Печатний дом, 2011) Korzun, T. V.; Lebediev, D. G.; Medinets, V. I.; Gazyetov, Ye. I.In order to take strategic managerial decisions long-term hydromorphological changes of boundaries and sizes of natural protected areas, such as nature reserves, national parks or game reserves should be traced. The most efficient method for quantitative assessment of parameters of long-term changes in spatial natural objects is the use of GIS and space imagery (Medinets, 2010).
