Results of monitoring of natural and anthropogenic agro ecosystems transformation in the Voronezh Region for the period of agricultural environmental management

Abstract

The paper deals with the theoretical analysis of peculiarities of agricultural nature management influence on the components of natural environment in the Voronezh Region. A retrospective analysis of soil research reveals a degree of its degradation. Dynamics of agro ecosystems development and the degree of change in the natural background of vegetation are determined; the peculiarities of agricultural impact are shown. The value of land resources in the Voronezh Region is determined by their fertility. The State Center of Agrochemical Service Voronezh and the State Station of Agrochemical Service Talovskaya control the structure, dynamics and condition of soils. As a result, soils of agro ecosystems on phosphorus, potassium, humus, acidity, heavy metals, mineral fertilizers and pesticides are comprehensively monitored. The Land Committee for the Voronezh Region reveals violations of the land legislation. Agro ecosystems have an unclosed cycle of biogenic elements. This is related to the loss of nutrients during harvesting and the activation of erosion processes. Changes in the balance of basic soil nutrients reduce the quality and yield of crops. Agro ecological monitoring includes systematic observation, study and analysis. In this regard, there is a need for research into the significant magnitude of the associated factors. The existing system of regional monitoring is based on the repeatability of soil, agrochemical and bacteriological studies of agroecosystems. Both continuous and local agro monitoring is conducted. It should be noted that agroecosystems of the region are insufficiently provided with biogenic elements, microelements and in this connection there is a need to create a model of balanced agricultural environmental management.
