The main objective of this study is to analyse the main pedogenesis factors that have contributed to the formation of soils in Seca?, Timi? County, Romania, using modern methods. The pedological data found in the study are represented by the transformation of analogue maps into digital maps using the GIS method. To begin with, the study area, geomorphology, geology, hydrology and hydrography of the locality, climate and vegetation conditions, decisive factors in the formation of soils in the study area were delimi...

Biochar application to agriculture soil has been recommended as a strategy to reduce increasing atmospheric carbon dioxide (CO2) concentrations and mitigate climate change. Significant suppression of soil CO2 emissions following biochar amendments has been demonstrated in short-term laboratory incubations by several authors, yet evidence from long-term field trials has been contradictory. This study investigates whether biochar addition to the soil could suppress soil CO2 emission under field conditions after 6-th...

The importance of land assessment activity consists in the fact that the data provided by these studies constitute the basic documentation for establishing the most appropriate practical measures for protection, improvement and rational use of soils for biomass production in an optimized and rigorous dynamics. correlated with the growing demands of environmental protection. The evolution and fertility of soils is conditioned by a large number of their individual properties and by many specific processes that take ...

The soils potential is the result of interdependence between the characteristics of the vegetation and the natural environment, also the level of production is the result of the influence of determining factors: natural environmental factors and technological factors. The influence of biotope relief factors on the above-ground vegetation is a direct consequence of the altitudinal differentiation of climatic conditions, a vegetation layer and implicitly a rather varied and complex area soil cover. It is unanimously...

Erosion dominates among the degradation processes of chernozems (black soils) in Ukrainian. It covers 32% of the total area of agricultural land - 14.9 million hectares. The development of erosion processes depends on the combined effect of factors: climatic, geomorphologic, geologic (including the characteristics of parent rocks), hydrogeologic and technogenic impact. The purpose of the research is the analysis of natural and technogenic factors of chernozems degradation in Ukraine to develop the principles of pr...

The paper presents the effect of zeolitic volcanic tuff on soil fertility as a consequence of treating soil with zeolitic tuff supplies (clinoptilolite rich tuff). This high silicon tuff type and the essential features of the clinoptilolite has generated in time changes in soil properties like soil reaction, an effective pH buffering, increase of water absorption and cation exchange properties. The effect of using three different doses of zeolitic volcanic tuff, with and without ammonium nitrate addition as fertil...

The industrial cultivation of American cranberry (Vaccinium macrocarpon Aiton) in Latvia was started during last 20 years with total plantings of more than 125 ha today. As a native wetland plant, commonly cranberries grows on poor, acid soils and are characterized as nutrients low requiring crop, however, balanced plant nutrition is vitally important to realize the full potential of cranberries as crop, to ensure adequate growth and yield production. Previous results obtained by authors from different cranberry p...

The paper deals with soil properties characterized the intrinsic peculiarity of studied Chromic Cambisols from the Upper Thracian Lowland, in the Southern Bulgaria. To fulfill the aim, a systematic survey and sampling have been carried out on the terrain with conventional and organic systems of farming. Soil physical, chemical and physicochemical properties were discussed including the analyzed data for particle size distribution, content and composition of organic substances, cation exchange capacity, soil bulk d...

The paper deals with statistical analyses of data on soil properties of Pellic Vertisols selected from the eastern as well western part of the Upper Thracian Lowland, in Southern Bulgaria. Based on the survey in 2019, 2020 and 2021 at conventional and organic farming the data was processed using the statistical package Statgraphics (Anova). Soil textural class was the same a light to heavy clay and the total porosity was low. Natural variability of soils was due to imposed local separateness of organic farming fro...

The purpose of the study and research undertaken over a long period of time has its origins in current scientific and practical concerns regarding the accumulation of knowledge about the physical-geographical characteristics and of its zonal particularities, as an element that define the structure of the land fund and the quality of soils, necessary to substantiate the technologies of sustainable management of the physical, geographical, climatic and edaphic conditions from that space. The issue addressed is a com...

One of the most important properties of soils is soil texture. Soil texture is defined as a collection of soil particles of different sizes - i.e. grain size. Particle analysis is a laboratory process that causes material dislocation into individual particles. The methods for the actual soil grain size analyses are based on the standard. This is the sieving test, the density test or the pipetting method. These methods are well known and widely used. The soil is then usually classified according to the triangular d...

The paper presents the complex pedological framework where the high-precision sensors from the meteorological stations are tested in order to remotely transmit the soil parameters with express reference to the NPK content and the water content of the soil. In the context of climate change, the interest in continuous, "in situ" knowledge of soil moisture and macroelement content is high because soil properties are correlated with the mathematical simulation of how crops are formed on agricultural plots. While regio...

The main purpose of the research carried out through 2016-2021, on a chernozem type soil, with remarkable fertility characteristics, located in the lower Plain of Banat, finds its origin in the current scientific discussions and practical preoccupations, which are more and more intense, as it is imperative find and developed an integrated management, which is agronomically efficient, in the current context of global climate change. These represent a major challenge for the agricultural sector, in order to ensure w...

The objective of this paper is the morphological characterization as well as the establishment of soil quality classes in the commune of Dubova, Mehedinti County, Romania. Soil is a primary component for plant production, although it is often considered only as a physical support for plant growth. However, the concerns of mankind over the sustainability of agriculture have made it possible to consider that soil is a living, high-quality system and should, therefore, be preserved. This is the result of several inte...
