Soil is an indispensable natural resource for the existence of various ecosystems and human activities, such as agriculture, silviculture and, pastoral activity. In addition to water, soil is the most important resource for life on Earth. Internationally, soil functions were defined and dealt with at the European level. The purpose of this study is...
Soil organic carbon (SOC) and total nitrogen (TN) stocks are crucial for the development of wild plants and crops. This paper examines the current SOC and TN stocks and their variability within land uses under different environments , assessing the relationships between SOC and TN stocks with basic environmental properties and quantifying the magni...
The aim of the research was to evaluate the role of the microbial composition of synthetic microbiomes for soil carbon evolution. The microbiomes inoculated into the soil (M1-M9) release exometabolites that influence the transport of nutrients in the soil and the dynamics of the energy potential. Thus, after the inoculation of microbiomes in the so...

The rational and efficient management of land resources, in the frame of a sustainable agriculture and environment protection, have to be based on the operational, and at the same time, more detailed and accurate knowledge of soil resources. This knowledge is based on soil information obtained by carrying out soil surveys and field research, and by...
Soil organic carbon (SOC) is an important parameter in the context of global warming, and a special attention should be given to its dynamics. The purpose of this paper is to test the existence of SOC losses from the soils taken for farming for more than 25 years in some areas of the Danube Delta. Another objective is to quantify such SOC losses if...
Active C, as a measure of the level of chemical oxidation of organic matter, reflects the carbon available to microorganisms. Soil respiration, as a direct way to estimate edaphic microbial activity, could be a measure of the fluctuations of carbon stocks in soils. To determine the ability of soil respiration to evaluate such fluctuations we used s...
The current status of Great Brăila Island is the result of an extensive activity of damming/draining/land reclamation of the Brăila Swamp with the aim to be used in agriculture. The final areas obtained from this complex activity preserve the specific variability of the flood areas. In order to be used in agricultural purposes, they need crop techn...
Soil organic carbon (SOC) sequestration generally occurs in wet ecosystems such as river flood plains and deltas.

Soil represents an extraordinary rich source of microorganisms responsible for its most important functions in terrestrial ecosystems. An important property certain of these microorganisms confer to soil is the suppressiveness, the property of soils to inhibit the development of pathogenic agents. Recent research focused on soil beneficial microbia...
Suppressiveness is the property of certain soils to inhibit or limit the development of pathogenic species due to the presence of microbial antagonists. Research has been carried out to characterize the microbial communities in the Calcic Chernozem (WRB) under cultivated forest from Enisala, Tulcea county. The bacterial microflora was dominated by...
The soil classification system SRTS-2012, in use in Romania since 2013, was made correlated with the previous most recent two systems – SRCS-1980 (used in the period 1980-2002) and SRTS-2003 (used in the period 2003-2012). For that correlation, related to the diagnostic and taxonomic elements (terms) existing in SRTS-2012, some new terms and some m...
The soil water retention curve or the soil water content-matric potential relationship expresses the capacity of soils to store water for plant growth, which is a very important soil property for irrigation and hydrological modelling. Due to relatively long time involved in the determination of water retention curves, there is an increasing interes...
