This project will be carried out to improve energy crops Sunflower Research and Analysis of heavy metals in the soil. Explore the integration of plant growth hormones and chelating vegetation restoration soils contaminated with heavy metals and further assessment of energy crops Sunflower heavy-metal contamination of soil remediation operation -cum- related environmental factors intended . By experiment and explore plant growth hormones and heavy metals on the growth scenario explants ( explants morphological analysis ). The experiment’s results indicate that GA3 can increase the growth rate of the plant：The average increment of the heavy-metal-added-only group is 18.89 cm; the average increment of the GA3-added group is 19.5 cm; the average increment of the EDDS-added group is 19.0 cm; the average increment of the GA3+EDDS-added group is 20.4 cm. The experiment’s results indicate that EDDS can increase the solubility of heavy metals in soil and enchance phytoextraction ：the plant accumulates a concentration of the heavy-metal-added-only group is  7.635±0.14 mg/kg; the plant accumulates a concentration of the GA3-added group is 10.522±0.212 mg/kg; the plant accumulates a concentration of the EDDS-added group is 17.037±0.637 mg/kg; the plant accumulates a concentration of the GA3+EDDS-added group is 16.216±1.503 mg/kg. Compared with the conventional methods of phytoremediation, these integrated measures can actually spur the growth of plants .

Nowadays it is hard to find a country with a big number of lands, which are non-used in any sphere of production. Taking into account hard ecological situation on the planet, each year more and more countries join to zero waste production. The agricultural branch is not an exception. Searching and creation of renewable energy sources are the main subjects of study for scientists in many fields of science. Starting from the 70s in Sweden government implemented the production of renewable energy. That energy based on burning the products of plant origin. At this period on the planet oil crises was increasing. This fact motivated scientists and businessmen for searching chip and effective energy sources. One of such sources is the biomass of fast-growing plant species which can be successfully recycled into biofuel. Renewable energy production in Ukraine is only on the first phase of development. A major limiting factor is the issue of determining the eligibility criteria of soils on which one can place the plantation of energy crops. It is noted that there is a possibility of growing energy crops on hydromorphic soils of floodplains, which are not used in traditional farming and forestry. Determining of soil limiting factors that can affect the growth of energy crops was conducted in the floodplain of river Vilhovatka, Novo-Vodolazhskiy district, Kharkiv region in 2016. Researches of the development and growth of energy crops (energy willow and giant miscanthus) were held on the meadow alluvial hard loamy soil and on meadow-marsh alluvial hard loamy soil. These soils by their genesis belong to azonal ones. High developed accumulative processes, which serve for organic and both macro and microelements conglomeration, are the specialty of their soil formation. Specific acid-base regime is inherent for hydromorfic soils. It’s caused by their periodical or constant water logging. For both soils the parent rock is an oxbow alluvium. The level of ground water occurrence was installed by drilling in spring, summer and fall. Energy willow – is one of the willow species that is processed for solid fuel. The usage of hydromorphic soils for willow planting has good perspectives. These soils can’t be used in agriculture without drainage. Here lies a clear parallel and duality of energy willow – the nature of its cultivation is more similar to food crops, but in contrast, willow grows on typical forest soils. In addition it can be mentioned that willow plantations have been used as a factor of preventing erosion for a long time already. The plants develop strong root system that allows consolidating river banks, gullies and ravines. Giant miscanthus – is a perennial grass that in botanical features reminds cane. The benefits of growing this crop lie not only in its growing for energy needs. Giant miscanthus has the following characteristics: tolerance to almost all types of soils; resistance to salinity (which is important in terms of its possible growth on alluvial-meadow saline soils); ability to grow on heavy soils; the ability to produce large amounts of biomass, which is relatively easy to collect and process with the existing technology and, of course, it’s ability for significantly improving of the environmental situation in forest landscapes. The paper presents the results of studies of the establishment of factors that affect the growth of energy crops in flooded soils. It was found that the main limiting factors are: the level of occurrence of groundwater and the concentration of heavy metals. Depending on the type of floodplain soils the level of groundwater occurrence varies considerably. This factor generally determines the character of the growth of the studied crops. Once again it was confirmed that the floodplain soils contain high concentrations of iron, including ferrous (Fe2 +) and oxide (Fe3+) forms. It is shown that the form of ferrous iron in high quantities is a limiting factor for normal growth and development of energy plants. On the meadow alluvial soil of the central floodplain energy crops grew much better (especially energy willow) than in the meadow-marsh soil of the terrace floodplain. Giant Miscanthus showed better stability, compared to energy willow, to its growing conditions. Also the article deals with the issue of energy willow phytoremediation ability, through which it is possible to partially solve the problem of some soils’ contamination with heavy metals.

The structure of the air-water interface forms a boundary layer that involves biological ,chemical geological and physical processes in its formation. Freshwater and sea surface microlayers form at the air-water interface and include a diverse assemblage of organic matter, detritus, microorganisms, plankton and heavy metals. The sampling of microlayers and the examination of components is presently a significant area of study because of the input of anthropogenic materials and their accumulation at the air-water interface. The neustonic organisms present in this environment may be sensitive to the toxic components of these inputs. Hardy reports that over 20 different methods have been developed for sampling of microlayers, primarily for bulk chemical analysis. We report here the examination of microlayer films for the documentation of structure and composition.Baier and Gucinski reported the use of Langmuir-Blogett films obtained on germanium prisms for infrared spectroscopic analysis (IR-ATR) of components. The sampling of microlayers has been done by collecting fi1ms on glass plates and teflon drums, We found that microlayers could be collected on 11 mm glass cover slips by pulling a Langmuir-Blogett film from a surface microlayer. Comparative collections were made on methylcel1ulose filter pads. The films could be air-dried or preserved in Lugol's Iodine Several slicks or surface films were sampled in September, 1987 in Chesapeake Bay, Maryland and in August, 1988 in Sequim Bay, Washington, For glass coverslips the films were air-dried, mounted on SEM pegs, ringed with colloidal silver, and sputter coated with Au-Pd, The Langmuir-Blogett film technique maintained the structure of the microlayer intact for examination, SEM observation and EDS analysis were then used to determine organisms and relative concentrations of heavy metals, using a Link AN 10000 EDS system with an ISI SS40 SEM unit. Typical heavy microlayer films are shown in Figure 3.
