The results of the assessment of soil respiration (CO2 emission from soil) in three regions (Chuvash Republic, Ryazan and Kursk regions) are presented. Agrarian (crop and livestock) and natural ecosystems are combined into seven groups: croplands, pastures, hayfields, abandoned lands, forests, stockyards and open compost storages.CO2 emissions were...

A comprehensive study of the net carbon balance of Lgov administrative district (Kursk oblast) in the Chernozem zone of the European part of Russia is carried out. The data sources included field estimates of carbon dioxide and methane exchange between soil and atmosphere, above- and below-ground phytomass stocks, simulation models parameterized on...

Post-harvest crop residues are the main carbon source for arable lands. The aim of this research was to determine the amount and portion in the phytomass of post-harvest crop residues of major crops and carbon, which is input to soil with them. For this purpose, samples of winter and spring wheat, barley, oats, and soybean were taken in five farms...

We analyzed four years field observations (2017–2020) of soil CO 2 efflux from Chernozems of arable and foreststeppe ecosystems of Kursk region (Russia), which correspond to the period of the maximal current warming. Three wellknown simulation models of different structure and variable sets (DNDC, RothC, T&P) and nonparametric regression analysis w...

On the basis of long-term meteorological data and research results in a long-term stationary experiment of 1971-2020 a retrospective analysis of changes in air temperature and precipitation in the eastern region of the central climatic zone of the Kirov region was carried out and the influence of these characteristics on the dynamics of the yield o...

Carbon calculators are programs for calculating greenhouse gas emissions (a carbon footprint) from agricultural production on the farm scale. They are created on the base of the IPCC methods but have not been used in Russia yet. The purpose of this study is to analyze the effectiveness of their application to assess emissions from livestock product...

The paper focuses on the applicability and adaptation of the novel international concept of Land Degradation Neutrality (LDN) of the United Nations, as applied to the territory of Russian Federation, taking into account the large variety of its soil and climatic conditions and economic approaches, as well as the historical past. In particular, in t...

The concept of land use adaptation to climate change and a short history of its formation in Russia are described. The global problems and disadvantages of the adaptation policy are listed, the Russian approaches and developed methods of land use adaptation to climate change are specified. Although there are a lot of legislative acts and scientific...

Статья посвящена особенностям цикла углерода в почве, которые формируются в результате сельскохозяйственного использования и должны быть учтены при матема-тическом воспроизведении, в том числе оценке эмиссии парниковых газов и специфи-ческого углеродного режима пахотных почв. Разработана классификация углеродных моделей, согласно которой они раздел...

Two biogeochemical simulation models describing carbon turnover in soil, the DeNitrification–DeComposition (DNDC) model and the Rothamsted Long-Term Field Experiment Carbon (RothC) model, have been parameterized in accordance with the conditions of arable leached chernozems of Kursk region and validated based on soil СО2 emission measurement data a...

The retrospective dynamics of major components of the carbon cycle under land use changes in the Central Forest zone of European Russia was investigated. This area is known as one of the most important agricultural and economical regions of the country. We applied the process-based simulation model DNDC (DeNitrification-DeComposition) recommended b...

Работа посвящена параметризации имитационной модели DNDC (DeNitrification-DeComposition), позволяющей оценивать компоненты биогеохимического цикла углерода в пахотных почвах на европейской территории России (ЕТР). Параметризация базируется на данных официальной статистики, информации из литературных источников и результатах первичной апробации моде...

The approbation of the DNDC (DeNitrification-DeComposition) model was done with the aim to estimate an opportunity of model using for analysis of carbon and nitrogen exchange and greenhouse gases dynamics in agroecosystems of arable soils in the Central Non-Chernozem Zone of Russia. The research can be divided into two blocks: estimation of model s...

The paper analyzes micrometeorological observations data based on the Bowen ratio and reveals the statistical regularities of changes in the carbon dioxide balance depending on environmental conditions. The correlation, regression, cluster, and factor analysis methods were used. Uzbekistan semideserts are the source of carbon dioxide for the atmosp...

Agrometeorological conditions in Central Non-Black Soil zone and their impact on winter rye yield in the trial area and under production conditions are determined using the methods of the correlation, regression, and factor analysis. According to the obtained data, the temperature factor has the greatest impact on yield whereas the moisture regime...
