Purpose. To study the Poltava region landforms as a natural recreational and touristic resource to optimize its use in tourism. Methods. Analytical synthesis, comparison, deduction. Results. Poltava region landforms due to their flat nature make the safe conditions for touristic ac-tivities. In compare to piedmont or low-hill terrain regions it attracts less attention of tourists, does not create the conditionals of high biodiversity and is characterized by high degree of anthropogenic devel-opment. The research was done for studying of geologic objects of Poltava region that can be interesting for tourists. We considered their location, origin, scientific and conservation value, perspectives for use in tourism. The origin of objects is connected to both endogenous (Rock - granite register", granitoid out-crops, Keleberda, Vysachkivsryi saline dome) and exogenous processes that are mainly erosive (Butova Gora, Brusia, Golovleva Krucha, Lysa Gora) and glacial (mount Piviha). All objects are components of the natural-reserve fund of Ukraine. To assess the significance of objects the points system was created based on their comprehensive nature. Most objects are combined with other geological landmarks with natural and anthropogenic origin, natural water, areas with preserved vegetation that increases their value. Many of objects has a historical value (Rock - granite register", Keleberda) or are connected to important historical events (mountain Piviha) and the activities of famous personalities (Golovleva steep). This is a reason why the biggest amount of points was given to such objects as Rock – “granite register”, granitoid outcrops in the Kamiani Potoky village , Butova Gora, Keleberda. On the other hand the lack the tourist infrastructure reduces the possibility of using some objects for tourism development. Thus, one of the most contrasting and attractive objects - Mount Piviha - is esti-mated by average number of points because of lack of tourist infrastructure. Conclusions. The landforms of Poltava region as a natural recreational and tourist resource creates significant opportunities for development of different kinds of tourism, including cultural, walking, water, health, coastal, environment-oriented, scientific tourism and photo tourism. The creation of the recreation infrastructure will allow involving geological and geomorphological objects more actively to tourist activity and increasing efficiency.

As a result of the conducted researches necrosis of leaves and pine-needle of trees is exposed in central part of Kremenchug city. The accumulation of lead, iron, copper in the leaves of arboreal breeds has been investigated. Possibility of use the results of research data in planting of greenery of cities is examined for the bioscrubbing of environment.

The methodological procedure of comprehensive evaluation of soils of farms in Kremenchugskiy, Semenivskiy and Hlobynskyy districts of Poltava region is substantiated in the work. The analysis of geological and geomorphological, climatic, landscape-geochemical conditions have been carried out in the districts by analyzing groups of factors, as: natural, geochemical and anthropogenic pressures.

Accumulation of nitrates in vegetables having grown mainly within the limits of the Kremenchug district is exposed in the result of carried out researches. The average and maximum concentrations of nitrates in vegetables were analised. For most vegetables exceeded the MPC only maximum concentrations of nitrate, and the average value of concentration - in the normal range. Causes and factors of nitrate accumulation in crops: non-uniform application of fertilizers spreaders from the use of incomplete, inadequate transportation and storage technologies fertilizers and soil properties, meteorological conditions, morphological and physiological characteristics of individual plants, plant variety, and so on. The measures to reduce nitrate content in vegetable production: the use of slow acting polymeric forms of fertilizers, fertilizer granules coating protective film, capsules, local application of nitrogen fertilizers.
