The landscape concept should give a fundamental assessment of the intensification extent of agricultural prospects. A detailed agroecological examination of all components of the natural-territorial complex, the creation of simulation models of their dynamics and the adoption of optimal decisions based on the results of forecasts should be carried out. The purpose of landscape analysis of natural resources is a comprehensive assessment of climatic, soil, plant and animal factors, establishing the relationship of landscape components with farming systems. Any landscape in the process of its development is exposed to impacts, and its stability has its limits. The stability threshold, expressed through the preservation by the landscape of its parameters and properties, and the critical impact quantities are determined in each case. General criteria for the natural stability of geosystems are their high organization, intensive functioning and geosystems functions balance, including biological productivity and renewability of vegetation cover. These qualities are determined by the optimum ratio of heat and moisture and are expressed by the development of soil cover, and ultimately, soil fertility. Landscape-ecological analysis of the territory makes it possible to establish the composition of agricultural and non-agricultural land, taking into account the heterogeneity and stability of a particular landscape, the occurrence of geochemical and biological processes in it, as well as to link the system of agriculture, land reclamation and specialization of the agricultural organization. The main element of Novosyolovo district landscape is agricultural land; the lands of the forest fund are the second largest area of natural geosystems. The degree of change in agrolandscapes is estimated on the basis of the existing structural and functional organization of agricultural lands, their quality state. It was established that plowing is low and it does not exceed the allowable limit, the forest cover of the district is close to optimal.
About 50% of the world’s distribution of the richest soils on the planet, black soil, is concentrated in Russia. On black soil, 75% of the gross output of grain crops and 50% of livestock production are manufactured. However, the current state of black soils causes concerns about the increasing degradation that threatens Russia’s food security. Black soils are a subject to significant anthropogenic stress; first of all they are exposed to agricultural impact. The problem of degradation of arable black soils is largely due to the deterioration of agrophysical properties and the degree of degradation varies in different soil-climatic zones. The granulometric compositions, density of soil structure, general porosity and water permeability depend on the nature of the soil use. Throughout the entire range of the studied agrophysical soils properties, arable black soils are inferior to virgin analogues located in similar conditions of the landscape. Post-irrigative soils transformed into a set aside are inferior in their agrophysical properties to virgin analogue, but surpass arable soils in some indicators. The range of unfavourable properties of black soils acquired as a result of irrigation is quite wide and manifests itself at almost all levels of their structural organization. It should be noted that irrigation with ecologically safe irrigation norms of 300 m3 / ha does not impair the physical properties of the soil, in contrast to heavy irrigation norms, that determine the unidirectional and noticeable expression of the main indicators in the direction of their deterioration.
The methodology for calculating the cadastral assessment of land in recent years has undergone a number of changes in general, and in particular in establishing the adequate value of land plots in settlements. When determining the cadastral value of land as a part of land in settlements, factors affecting pricing are not always taken into account. One of these factors can be ecological conditions of the environment and engineering - geological conditions of construction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
