Abstract
Background
Irrigation of lands over time leads to such negative processes as land salinization and waterlogging, reduction of soil fertility, changes in the chemical composition of groundwater, and the emergence of linear and irrigation erosion. The land improvement (ameliorative) categories adopted in Russia and several post-Soviet countries determine their suitability for agricultural use and the focus of measures to preserve potential soil fertility.
Aims
The study aims to build a mathematical model to assess the intensity of the reduction and restoration of irrigated lands’ state in the Republic of Bashkortostan.
Methods
The methods of the theory of random processes are proposed to estimate the intensity of reduction and restoration of irrigated lands’ state on the territory of the Republic.
Results
As a result of the calculations, the values of intensities characterizing changes in the state of land in the region were obtained. The practical significance of the developed model consists of the possibility of short-term forecasting and determination of the necessary intensity of land quality restoration taking into account planned values during the given period.
Conclusions
The offered indicator of intensity and the method of its definition can be used in research of similar processes proceeding on agricultural lands within the limits of large spatial units.
期刊介绍：
Established in 1922, the Journal of Plant Nutrition and Soil Science (JPNSS) is an international peer-reviewed journal devoted to cover the entire spectrum of plant nutrition and soil science from different scale units, e.g. agroecosystem to natural systems. With its wide scope and focus on soil-plant interactions, JPNSS is one of the leading journals on this topic. Articles in JPNSS include reviews, high-standard original papers, and short communications and represent challenging research of international significance. The Journal of Plant Nutrition and Soil Science is one of the world’s oldest journals. You can trust in a peer-reviewed journal that has been established in the plant and soil science community for almost 100 years.
Journal of Plant Nutrition and Soil Science (ISSN 1436-8730) is published in six volumes per year, by the German Societies of Plant Nutrition (DGP) and Soil Science (DBG). Furthermore, the Journal of Plant Nutrition and Soil Science (JPNSS) is a Cooperating Journal of the International Union of Soil Science (IUSS). The journal is produced by Wiley-VCH.
Topical Divisions of the Journal of Plant Nutrition and Soil Science that are receiving increasing attention are:
JPNSS – Topical Divisions
