Soil phytotoxicity studies were performed with different doses of creosote by means of the PHYTOTOXKIT test, using Sinapis alba, Lepidium sativum, Sorghum saccharatum as test plants. The obtained results indicate highly signifiant effect of the creosote dose, duration of soil incubation, type of test plant and period, after which the root length measurement was performed during the phytotoxicity index...
Study on soil infiltration rate as part of water cycle is essential for managing water resources and designing irrigation systems. The present study was conducted with the aim to compare Kriging, inverse distance weighting (IDW), multilayer perceptron (MLP) and principal component analysis (PCA) methods in the interpolation of soil infiltration in furrow irrigation, and determine the best interpolation...
The objective of this work was to the study the erosive force of raindrops and the shear stress on the soil erodibility of disturbed and saturated agricultural soil. A mathematical development was used to determine a new approach to the shear stress. The soil erodibility is calculated using the WEPP (water erosion prediction project) model. To realize this work, an experimental study was led in a...
Tillage is one of the most important practices that have a significant influence on the soil hydro-physical properties. In this study, the impact of the type and number of input variables with five different methods of the Retc model to predicting the moisture retention curve and soil water content in three surfaces tillage NT (No-tillage), CP (Chisel Plough) and MP (Moldboard Plough) and the impact...
Closed depressions (CDs) are common small forms occurring in the European loess belt. The age, origin and evolution of these forms is highly debated. Some CDs are reproduced in the loess cover. Their formation was directly influenced by the relief of sediments underlying the loess cover and varying in terms of age and origin. Two depressions of this type were documented within the thin (8 m) loess...
The decomposition of organic matter on leaf litter substrat runs very slowly in nature resulting in the accumulation of litter in the ecosystem and has even become an organic waste that creates many problems. The research was dealt with the use of lignocellulolytic fungi inoculum consisting of 3 isolates: Aspergillus fumigatus (cellulolytic), A. tubingensis (xylanolytic) and Geotrichium sp (ligninolytic)...
One of the most important problems threatening the health of natural resources and, in turn, the food safety of societies is environmental contamination. Heavy metals are considered as the environmental pollutants. The entry of heavy metals into the soil is done through the atmospheric sources and mostly via melting plants, oil refieries and power plants. Due to the mazut consumption in some seasons,...
The most important feature of the primary accumulation of different facts about the properties of soils, their fertility and ways of cultivation is the human awareness of soil as the environment of growth and development of plants, as well as the existence of a large variety of soils and the need for their differentiated use in the agriculture and different taxation systems. Monuments are important...
The influence of long-term use of mineral and organic fertilizers, crop rotations, plant residues, soil treatment systems on humus content of common chernozems and stabilization of productivity of field crops in the arid conditions of the Middle Volga region is considered on the example of researches in the Samara area. The zone climate of field experiments is characterized as extremely continental...
The world agriculture uses about 70% of the world water resources in irrigation. The concern over the sustainability of water use as demand for agricultural, industrial, and domestic uses continues to increase. Conflicts between particular sectors result in tensions, which sometimes lead to “water wars” in different parts of the world. It is the reason why many national and international organizations...
Salinization and sodification of agricultural lands in arid and semi-arid regions of the world are two limiting factors in the crop production. This study was conducted to evaluate the effect of readily available agricultural residues on changing some chemical properties of saline-sodic soils. Wheat, potato, sunflower, and canola residues were separately added into three saline-sodic soils at a rate...
A two-year field trial on maize (Zea mays L.) production was established to determine the influence of biochar, maize straw, and poultry manure on soil aggregate stability, aggregate size distribution, total organic carbon (TOC), and soil microbial biomass carbon (MBC). Seven treatments with four replications, namely CK, control; S, 12.5 Mg ha-1 straw; B1, 12.5 Mg ha-1 biochar; B2, 25 Mg ha-1 biochar;...
Soil quality is a measure of the condition of soil. The goal of sustainable agriculture is to maintain a non-negative trend in productivity while maintaining soil quality. Susukan is an area in Semarang, Central Java, Indonesia, which has developed organic farming to increase rice productivity and quality. The main objective was to determine the sustainability of organic rice cropping systems. The...
In the humid conditions, the most common ground forms are the ferruginous ones: ferrum concretions, marsh ore, ocher spots, etc. Mollic gley soils are widely spread along the periphery of marshes and are formed under the influence of mollic and gley processes on various soil-forming rocks under conditions of sporadically pulsating water regime and excessive moisture under the meadow and swamp biocenoses...
This research was conducted to evaluate the effects of biochar and barley residues on some physicochemical properties of silty loam soil and water erosion using water erosion simulator. Biochar was produced from pistachio shells under slow pyrolysis at 500°C under anaerobic condition. Biochar and barley residues were mixed to soils at three rates of 0, 0.5 and 1% (by weight), and 6.5 kg of soil was...
The aim of the present research is the determination of soil color by spectral bands and indices obtained from MODIS images. For this purpose, soil samples were collected from East Azerbaijan Province (Iran) and their color and texture were investigated through Munsell color system and hydrometer method, respectively. Stepwise regression, principle component analysis and sensitivity function methods...
Degradation of pastures caused by anthropogenic and climatic factors leads to desertification, loss of soil fertility, reduces productivity of the pasture grass and it is a prerequisite for socio-economic problems. Pastures of Western Kazakhstan cover more than 70% of the lands under economic use and are the main fodder source for the farm animals. In the late years, degradation of pastures in Western...
Understanding of P transformations following organic amendments addition to highly calcareous soils is necessary for developing better management practices that can help enhance P fertilizer use efficiency. Phosphorus solubility and availability for plant uptake under the conditions of arid calcareous soil is very low, making P nutrient supply a critical issue under these conditions. The aim of this...
The article contains the authors’ reflections on the formation and substantiation of many aspects in soil science, concerning its connections with social sciences. Arguments about the exceptional importance of soil resources in the modern world and the importance of scientific research in soil science, which can become an important instrument of solving social problems, are found. It is shown that...
In this paper, the content of metals (Cd and Pb) was investigated in soil-plant system of Holosiyiv green park area in Kyiv. Kyiv is the capital and largest city of Ukraine, and has an anthropogenic load. Metals pollution in various degrees in green park areas may affect people’s health through different paths. We propose to control the lead contamination in soil because Pb concentration levels were...
