“…Intensive tillage and fertilizing in crop production leads to the rise carbon dioxide emissions increasing greenhouse effect and global warming [15][16]. According to different estimates, AFOLU sector accounts for 14-28% of total greenhouse gas emissions [17][18] with 35% of CO2, 47% of CH4, 53% of N2O and 21% of NO globally being emitted by soils [19].…”

The current research is aimed at working out methodological basis of assessing conservation agriculture efficiency based on the practical experience. The traditional system of land use is now to be totally reconsidered due to its negative environmental effects with new practices to be implemented that can increase productivity, protect soil from degradation and deal with the current climatic crisis, i.e. help adapt to the climate change, decrease greenhouse gas emissions and increase soil carbon sequestration. Conservation agriculture (CA) is the technology that can help overcome all the above mentioned challenges being defined as the approach of managing agricultural ecosystems that provides for the sustainable agricultural production, lower energetic and labor expenses and higher efficiency of utilizing soil and water resources. Given its major goal of preserving soil health conservation agriculture is to be evaluated based on the combination of ecological and economic effects, rather than on the economic effect separately. The current methods of evaluating eco-economic efficiency of the technology based on estimating soil carbon changes and methods of its recovery with adding organic fertilizers cannot be applied in practice now due to the lack of organic fertilizers and high costs of chemical analyses to measure soil carbon changes. The current study presents a new methodology to assess eco-economic effect of conservation agriculture practice based on assessing already adopted economic indicators and soil carbon changes dynamics (t CO2/ha/year) from specific agricultural practices with the subsequent estimation of carbon credit units that farmers can sell at a carbon market.

“…SSM aims to increase the content of SOM and increase the process of carbon sequestration, thereby contributing to the mitigation of climate change [7,8]. To achieve this, a "low-carbon" development strategy has been initiated in various countries around the world, which involves reducing carbon dioxide and methane emissions through the use of techniques that prevent the rapid mineralization of organic residues in the soil [9][10][11]. This strategy corresponds to the goals of the international initiative "4 per 1000" [12].…”

Estimation of Carbon Stocks and Stabilization Rates of Organic Matter in Soils of the «Ladoga» Carbon Monitoring Site

The establishment of a network of monitoring sites (term in Russian—«carbon polygons») for monitoring climatic processes as well as the emission and deposition of carbon compounds in various ecosystems is one of the priority tasks in the field of climate and biosphere conservation in the world. This paper presents the results of the study of the soil sections of the «Ladoga» carbon monitoring site. Folic Podzol (Arenic) and Fibric Histosol were considered. These soils are widely represented in the southern taiga subzone and can be used as benchmark monitoring soil sections. As a result of the analysis of chemical parameters, it was revealed that Fibric Histosol and Folic Podzol (Arenic) are characterized by an acidic reaction of pH, pronounced podsolization, and peat accumulation. Fibric Histosol stores a significant amount of soil organic matter (SOM) up to 42.95 kgC/m2. In the analysis of the molecular composition of humic acids (HAs) extracted from the studied soils, it was found that HAs from Fibric Histosol were characterized by a relatively high content of aromatic structural fragments (27–41%), while in Folic Podzol (Arenic), aliphatic structural fragments prevailed (up to 70%). The increase of aromatic structural fragments in the HAs composition indicates the stabilization and conservation of SOM. The creation of a monitoring network will make it possible to identify the main trends of SOM accumulation, determine the conditions under which accumulation occurs, and calculate its contribution to climate change on the planet.

“…For this reason, most of the chernozemic soils in the world are currently plowed. For example, Russia has more than 50% of the world's chernozems [2], more than 73% of which are plowed, and they cover about 54% of the country's arable land [3]. However, the productivity of the chernozem soils strongly depends on their health and status.…”

When soils are used for a long period of time as arable land, their properties change. This can lead to soil degradation and loss of fertility, as well as other important soil biosphere functions. Obtaining data on the trends in arable soil conditions over large areas using traditional field survey methods is expensive and time-consuming. Currently, there are large archives of satellite data that can be used to monitor the status of arable soils. The analysis of changes in the color of the surface of arable chernozem soils of the Belgorod region, for the period from 1985 to the present, has been carried out based on the analysis of Landsat TM5 satellite data and information about the spectral reflectance of the soils of the region. It is found that, on most parts of arable lands of the region, the color of the soil surface has not changed significantly since 1985. Color changes were revealed on 11% of the analyzed area. The greatest changes are connected with the humus content and moisture content of soils. The three most probable reasons for the change of humus content in an arable horizon of soils are as follows: the dehumidification of soils during plowing; the reduction of the humus content due to water erosion; and the increase in humus content due to changes in the land-use system of the region in recent years. The change in soil moisture regime has mainly been found in arable lands in river valleys, most likely conditioned by the natural evolution of soils. Trends of increasing soil moisture are prevalent. The revealed regularities testify to the high stability of arable soils in the region during the last few decades.
