В работе определены показатели влажности устойчивого заядания растений дерново-литогенных почв на красно-бурых глинах расчетным методом и методом вегетационных миниатюр и установлены причины расхождений этих подходов. Установлено, что для дерново-литогенных почв на красно-бурых глинах влажность устойчивого завядания растений составляет 6,4–10,1 %. Для исследованного типа техноземов характерно существенно неравномерное распределение этого показателя по профилю. Такие особенности сложения технозема можно рассматривать как негативную особенность для роста растений и формирования продуктивности экосистем. Верхние и нижние слои почвы со сравнительно меньшими значениями влажности устойчивого увядания растений разграничены средним слоем с повышенными значениями этого показателя. По результатам регрессионного анализа доказано, что наибольшее влияние на влажность устойчивого увядания растений имеет засоленность почвы. Для проведения расчетов был учтен этот показатель. Построенные педотрансферные функции дают возможность уменьшить трудозатраты для определения данной гидрологической константы и при этом получить показатель, который имеет очевидную экологическую значимость.
Ключевые слова: влажность устойчивого увядания растений, дерново-літогенні грунты, рекультивация.

Methodical approaches to assess sustainable plant wilting point moisture sod-lithogenic soils on reddish-brown clayLjads'kaja I.v., Mašlíková K. P., Zhukov A. V. Dnipropetrovsk State Agrarian [e-mail] indicators are defined in the work for sustainable zajadanija plant sod-lithogenic soils on reddish-brown clay calculation method and using vegetation miniatures and the causes of variances of these approaches. Found that for sod-lithogenic soils on reddish-brown clay humidity sustainable plant wilting point is 6.4-10.1%. For tehnozemov type examined is characterized by significantly unequal distribution of this indicator on the profile. Such features add of tehnozema can be seen as a negative feature for plant growth and formation of ecosystem productivity. The upper and lower layers of soil with comparatively lower humidity values sustainable withering plants separated medium layer with high values of this index. Based on the results of the regression analysis proved that the greatest influence on the humidity sustainable withering plants have soil salinity. For the calculation of this indicator was taken into account. Constructed pedotransfernye function enable to reduce labor costs to determine the hydrological constants and get an indicator that has obvious environmental significance.Keywords: sustainable plant wilting humidity, sod-lіtogennі soil, recultivation.

In the humidity indicators identified sustainable zayadaniya plant sod-lithogenic soils on red-brown clays calculation method and vegetation miniatures and set reasons for the discrepancies of these approaches. It was found that for the sod-lithogenic soils on red-brown clays humidity stable wilting plant is 6,4-10,1%. For the investigated type tehnozemov characterized by significantly uneven distribution of this indicator in the profile. Such features adding tehnozema can be viewed as a negative feature for plant growth and formation of productivity of ecosystems. The upper and lower layers of soil with relatively lower values of moisture for sustainable plant wilting demarcated middle layer with high values of this parameter. According to the results of regression analysis proved that the greatest impact on sustainable humidity wilting plants is salinity. This figure was taken into account for the calculation. Built pedotransfernye functions make it possible to reduce labor costs for the determination of the hydrological constant and still get a figure that has obvious ecological importance.
Keywords: sustainable humidity wilting plants, sod-lіtogennі soils remediation.

methodological approaches to the assessment of sustainable завядания plant moisture дерново - литогенных reddish brown soil and clayлядськая i.v., масликова to. p., bugs as well. in the.dnepropetrovsk state agrarian university of economicsZhukov _ dnipro @ ukr.netthe identified indicators of humidity of sustainable заядания plants дерново - литогенных reddish brown soil and clay calculation method and the method of вегетационных miniatures and identified the reasons for the differences of these approaches. the finding that дерново - литогенных reddish brown soil and clay is sustainable завядания plants is 6,4–10,1%. for a known type of техноземов is significantly uneven distribution of the target profile. adding such features технозема can be viewed as a negative feature for plant growth and the formation of the productivity of ecosystems. the upper and the lower layers of the soil with relatively lower values of humidity, sustainable plant wilt delineated middle layer with higher values of this index. according to the results of regression analysis proved that the greatest influence on the decay of plants has the salinized soil is sustainable. for the calculation of this figure was taken into account. built педотрансферные functions provide an opportunity to reduce the time for determining the hydrological constants and to obtain an estimate of, which has a strong environmental significance.key words: humidity sustainable withering plants, дерново - літогенні substrates, rehabilitation.
