Biogeochemical Principles of Plant Product Quality in Agrolandscapes with Typical Chernozems

Yehorova Tetiana, Palapa Nadiya, Nagorniuk Oksana, Sobczyk Wiktoria

Peculiarities of formation, distribution and fertility of typical chernozems on the territory of Europe as a whole and within the agricultural lands of Ukraine were given. It is noted that the existing agro-industrial characteristics of agricultural products least reflect the quality of raw materials and therefore are not analyzed as a factor influencing public health. The relevance of biogeochemical research of food (agricultural) raw materials and the introduction of new criteria for its quality were outlined. The purpose of the presented research was to expand the quality indicators of agricultural products on the basis of topical structure of agricultural landscapes and biogeochemical criteria for evaluating "typical chernozems – cereals and vegetables" systems. A system of biogeochemical parameters and quality criteria of plant products containing two components has been developed. The first component is the spatial differentiation of natural and agro-technological features of agrolandscapes (systems of rocks-typical chernozems-cultures), which highlight the prevalence of nutrients in bedrock, particle size distribution of typical chernozems and the ratio of their prevalence within the administrative regions of Ukraine. There are 12 groups of agricultural landscapes that differ in these features. A set of biogeochemical parameters for the distribution of essential elements in the components of the agricultural landscape, criteria for their ecological balance and impact on the quality of agricultural raw materials.Implementation of the proposed criteria for the quality of agricultural products was carried out on the territories of two agrolandscapes of typical chernozems in the Kyiv and Poltava regions.It was established that the physico-chemical balance of Zn, Cu and excess Mo in the rocks and soils of the agro-landscape of the Right Bank Forest-Steppe is not consistent with biogeochemical deficiency of copper and, in part, zinc in cereals (oats). The physico-chemical balance of Zn, Cu in the soils of the agro-landscape of the Left Bank Forest-Steppe does not agree with the biogeochemical deficiency of zinc in vegetable crops (potatoes, carrots, and beets). On the basis of the biogeochemical criteria for the distribution of Zn, Cu, Mo in agricultural landscapes, the proposed territorial measures to improve the quality of grain and vegetable products to prevent copper and zinc "hidden hunger" in the population.

Agrorecreational ecoparks in the quarries territory as a new type of urban production (on the example of Kryvbas)

The article analyzes the main conditions of formation of agrorecreational ecoparks in the quarries territory, which no longer perform their initial functions. Agrorecreational ecoparks are regarded as a new type of urban development in combination with recreational function for industrial cities. Thus agrorecreational ecoparks are researched as structural elements of both agroproductive and recreational complexes of a country. Depending on types of activity there have been established main functional subzones and their interposition according to the exploitation mode and territory security. The planning structure of an agrorecreational ecopark locates the subzones of scientific use in the middle of a park, in the most accessible places as they are main attraction for visitors. Natural landscape of recreational use subzone adjoins the scientific zone; service centers and utility zones are located along the edges of the park thus creating a buffer area. The main groups of relief forms have been analyzed, which directly affect the planning structure of the researched parks. The main types of agrorecreational ecoparks in terms of relief forms have been identified; dimensional and spatial peculiarities of organization of such territories have been determined. In the context of a complex terrain and intensive soil erosion the major component of agrorecreational ecoterritories is geoplastic relief with drainage network (columbine), which determines precipitations run-off and the water regime of the park in general. The main notions and special features of landscape columbine and geoplastics (terracing) have been analyzed. The major types of agrolandscapes under the conditions of agrorecreational ecoparks formation have been established.
