    Opis:
    The article presents the current distribution of arsenic in agricultural soils of Slovakia. The current concentration of arsenic (extracted with aqua regia) was measured and evaluated based on 318 monitoring sites of national soil monitoring system in Slovakia. Based on the obtained results, one can state that the average content of arsenic is lower than the valid hygienic limit for arsenic (25 mg.kg-1) for predominated sandy-loamy and loamy soils in Slovakia. Increased values of arsenic were determined only for the Horná – Upper Nitra region (anthropogenic impact) – 24.5 mg.kg-1 and for the Stredný – Central Spiš region (mixed anthrophogenic and geogenic impact) – 129.5 mg.kg-1. These regions belong to the most arsenic-affected regions in Slovakia, where the content of bioavailable forms of arsenic is also increased in the range of 0.013–0.997 mg.kg-1. The hygienic limit for bioavailable arsenic in soils of Slovakia is 0.4 mg.kg-1. Finally, there is a serious risk of arsenic transport from soil into the plants and food chain especially in case of acid soils. A higher risk of As presence seems to be in anthropogenically affected soils.

    Opis:
    Modern agriculture involves the implementation of a particular technological operation, according to the appropriate map-task, which is developed pre-based on diverse information. Knowledge of a certain structure of soil cover variability, obtained using information and technical systems of local operational monitoring of agro-biological state of agricultural lands, allows us to adopt effective operational decisions for efficient management of agro-biological potential of agricultural lands. Obviously, under such conditions, there is a need for fundamentally new approaches to agricultural production,which is to ensure the proper quality of technological operations. The quality of the implementation of technological operations is an integral indicator of the efficiency of production of agricultural products within the agro-biological field. The necessary quality of implementation of the basic technological processes in plant growing is provided by the integrated information and technical systems of operational monitoring of the agro-biological state of agricultural lands. In connection with this, the task is to obtain reliable data on the agro-biological state of the soil environment by reducing the error in determining the magnitude of the conductive properties of the soil, providing individual stabilization of the working electrodes and the mechanism of lifting / lowering working electrodes, copying inequalities of the soil environment, reducing the intensity of the destruction of the soil structure , self-cleaning of the working contact of the electrode and ensuring the stability of the electrical contact of the electrode with the soil, by instrument design perfection. The task is achieved by using the information and technical system of operational monitoring of the soil environment of the structure to determine the conductive characteristics of the soil environment.

    Opis:
    Available techniques for dealing with uncertainties in the agro-industrial complex and their use for describing and assessing the adequacy of the decisions taken are incomplete, and often ineffective, as they usually do not take into account the combination of "field-machine-technological material", which prevents acceptance effective solutions for managing agro-biological potential of agricultural land and, as a consequence, obtaining the maximum economic efficiency of agricultural production. Reliable estimation of variables of agricultural production parameters using the "field-machine-technological material" model makes it possible to provide optimal control of available technical equipment (machinery, sowing machines, etc.), agro-biological (humus content, presence of nutrients, micro-and macro elements, etc. in soil or plant ) and technological resources for making adequate decisions and managing agro-biological potential of agricultural lands, which will provide the necessary economic efficiency. The task is achieved by ensuring the proper quality of the implementation of technological operations that are an integral indicator of economic efficiency and allow providing the necessary economic efficiency through optimal and efficient management of technical means for optimal action on the agro-biological potential of the field and the use of available technological resources. Such control is possible with the use of information and technical systems of local operational monitoring, which are located on machine-tractor units and provide effective control of technological operations by acting on the executive bodies of agricultural machines on the basis of data characterizing the agro-biological state of the soil environment. Information and technical systems of local operational monitoring of the agro-biological state of agricultural lands are used in the following cases: - before performing a technological operation, - simultaneously with the implementation of the technological operation (sowing, fertilizer application, etc.), - during the growing season and after harvesting. This opens new prospects for organic farming using such "smart" agricultural machines.

    Opis:
    The article considers a comprehensive study of the problem of land relations development in the region. It identifies the main directions for their further development, which include improving the legislative framework, economic and monetary valuation of land, leasing land relations and ensuring the formation of a market for agricultural land and ecologically safe land use. The article aims to determine the interrelated components of the organizational and economic mechanism for managing land resources of agricultural enterprises in the context of ensuring land-use efficiency based on the choice of a land-use optimization model. The theoretical and methodological bases for the development of land relations in the conditions of market economy formation are generalized. The directions for improving the ecological status of agricultural land are justified. The state regulation of land relations is analyzed, and ways to improve land legislation are proposed. The directions of the formation and development of the agricultural land market are justified. The ways to improve the ecological condition of the land, taking into account the regional characteristics of the Vinnytsia region, are proposed. To determine the relationship of rational use and reproduction of resources, considering the problems of choosing the optimal strategy for the impact of the economy on the ecologization of land resources, the system of rational use and reproduction of natural resources is developed. The optimization model describing the conditions for the process of stimulating landowners and land users in the direction of protection and rational land use is established.
