Nowadays, the development of the greenhouse effect is caused not only by industrial facilities emissions into the atmosphere. The contribution of natural and anthropogenic sources of greenhouse gas emissions is becoming increasingly significant. For example, the amount of carbon dioxide produced by the decomposition of organic substances in the zones of degradation of permafrost increases every year. The contribution of the total emission of numerous dispersed sources of atmospheric pollution is also very significant. Traditional methods of control and limitation of greenhouse gas emissions in this case are irrevocable. The solution of the problem is possible only on the basis of the creation of controlled natural and technical systems. The task for the systems is to organize the flow of greenhouse gases from the atmosphere and carbon fixing in the stable components of the environment. The main area of this activity is the stimulation of bioproduction processes. This task is difficult to accomplish in the field of agricultural production. The main objective of the development of this industry is to meet the growing shortage of food products. Against the background of the threat of mass starvation in a number of regions of the world, the problem of the greenhouse effect loses its relevance.

Niaodao, a lakeside wetland, was used as the focus of this study to investigate the effect of rainfall changes on the greenhouse gas fluxes of wetland ecosystems. Wetland plots with different moisture characteristics (+25%, −25%, +75%, and −75% rainfall treatments and the control treatment (CK)) were constructed to observe in situ field greenhouse gas emissions at 11:00 and 15:00 (when the daily mean values were similar) in the growing season from May to August 2020 by static chamber–gas chromatography and to investigate the responses of wetland greenhouse gases to different rainfall treatments. The results showed the following: (1) The carbon dioxide (CO2) flux ranged from −49.409 to 374.548 mg·m−2·h−1. The mean CO2 emission flux was greater at 11:00 than at 15:00, and the +25% and +75% treatments exhibited substantially higher CO2 emissions. In addition, the CO2 flux showed a small peak at the beginning of the growing season when the temperature first started to rise. All treatments showed the effect of the CO2 source, and their effects were significantly different. (2) The methane (CH4) flux ranged from −213.839 to 330.976 µg·m−2·h−1 and exhibited an absorption state at 11:00 and an emission state at 15:00. The CH4 emission flux in August (the peak growing season) differed greatly between treatments and was significantly negatively correlated with the rainfall amount (p < 0.05). (3) The nitrous oxide (N2O) flux ranged from −10.457 to 16.878 µg·m−2·h−1 and exhibited a weak source effect throughout the growing season, but it was not significantly correlated with soil moisture; it was, however, negatively correlated with soil temperature. (4) The different treatments resulted in significant differences in soil physical and chemical properties (electrical conductivity, pH, total soil carbon, and total soil nitrogen). The rainfall enhancement treatments significantly improved soil physical and chemical properties.

The soil from three organically cultivated plots in Rioja Alavesa vineyards, specifically in Lanciego (Álava, Spain), and the foliage of their vines were analyzed. The aim of this study was to determine differences in soil and grapevine quality between different aged vineyards. The first 20 centimeters of the soil were sampled and leaves were collected during the growing season. The results show that the quality of the soil in the three plots was optimal and did not differ from reported values of soils from traditionally cultivated plots. The only element found at a lower concentration in the three plots and the leaves was iron. Organic cultivation of vineyards is a viable mode of cultivation and could help reduce greenhouse gas emissions and contamination by pesticides and fertilizers.

Emission Of Greenhouse Gases

Introduction. Global warming and so-called the “greenhouse effect” is one of the most discussed problems of physics and geopolitics, which has caused protest environmental movements in the world. Problem Statement. Widely discussed are both anthropogenic (the emission of greenhouse gases into the atmosphere) and the natural concepts of global warming with the dramatic effects of climate change on the planet and individual regions. Purpose. Evaluate the state of the problem, to present the results of research and measures to possible reduction of the greenhouse effect. Materials and Methods. Authoritative literary sources were used to analyze anthropogenic and natural factors of global warming, including an explanation of the processes from physics that manifest themselves during solar-geomagnetic activity. Results. Ways and directions of increasing the efficiency of energy use to reduce greenhouse gas emissions are identified. Conclusions. The greatest potential for increasing energy efficiency in the use of energy resources, and thereby reducing greenhouse gas emissions, lies in the heat supply sector of the country's housing and municipal sector. Prospects for further research are related to the development and implementation of organizational, economic and technological innovations in this energy sector.
