The aim of the study was to evaluate the impact of conventional till (CT) and no-till (NT) cultivation systems in long term experiment with maize on soil water dynamics using continuous soil moisture (SM) measurements in the 2014, 2015, 2016 vegetation seasons. The ability of HERMES model to simulate SM was also evaluated in Polish conditions. The long term experiment with maize is located in the...
The purpose of this study is to investigate the effects of rainfall erosivity index AI on the hydraulics of overland flow parameters such as the flow velocity, the flow depth, the flow regime, overland flow power and on soil surface characteristics, such as surface roughness and sediment concentration. The erosivity index AI represents six rainfall intensities, 31.40 mm·h-1; 37.82 mm·h-1; 69.49 mm·h-1;...

One of the major problems of rice cultivation in Guilan is traditional rice cultivation along with autumn tillage and burning last year’s residual, which besides wasting this valuable organic source is followed by environmental pollution in September and October each year. This study aimed to evaluate three different methods of tillage as far as soil physical properties and rice growth under crop...
One of the problems in the development of the agro-food industry is the production of enormous quantities of organic waste. In recent years, in order to minimize the negative impact of waste on the environment, emphasis is put on their recycling. Organic matter derived from poultry industry waste can be processed into other products, including compost. The aim of the study was to evaluate the phytoremediation...
This study was aimed at determining effects of increasing simultaneous contamination of soil with Pb and Zn at doses of 200, 400 and 800 mg·kg-1 and with Cd at doses of 5, 10 and 20 mg·kg-1 soil, after the addition of immobilizing agents (zeolite, diatomite, chalcedonite, dolomite, limestone, and activated carbon), on selected properties of soil. In the soil without the immobilizing agents, the highest...
In the soil cover of the forest-steppe zone, typical chernozems, which occupy almost 50% of the total area of arable lands that are insufficiently fertilized with organics and minerals, prevail. Our task was to investigate the potassium content in these soils in order to gain insight into its reserves and availability for agricultural plants. For this purpose, soils of this type of different granulometric...
Investigation results of the gross chemical composition of Malyi Polissya Rendzinas (Rendzic Leptosols) and its transformation under the influence of deflation have been revealed. The oxides percentage in soils, their distribution in the profile have been described, and differentiation soil profile indices have been calculated. The changes in Rendzinas gross chemical composition due to the detection...
The Atterberg limits display soil mechanical behavior and, therefore, can be so important for topics related to soil management. The aim of the research was to investigate the spatial variability of the Atterberg limits using three most common digital soil-mapping techniques, the pool of easy-to-obtain environmental variables and 85 soil samples in central Iran. The results showed that the maximum...
Rainfed lowland rice is grown in land where the irrigation systems depend on rainwater. The use of chemical fertilizers in large quantities in order to improve production of rice will result in soil quality degradation. In order to improve the condition of the soil, a system of organic farming was provided. The aim of this study was to quantify soil quality in rainfed lowland ricefilds using soil...
Surface roughness is a very important physical feature of soil, affecting various soil processes and accuracy of remote sensing data interpretation. Thus, there is a need to describe it quantitatively. The main aim of the paper was to show needs and benefits of collecting quantitative information about soil surface roughness which is the most relevant parameter used as an index to predict water and...
Acid sulfate soils in coastal wetland areas are particularly vulnerable to land-use changes. We identifid the potential impacts of land-use changes in the Can Gio coastal wetland area in Vietnam due to the reclamation of acid sulfate soils from shrimp farms. Our study applied the support of vector machine algorithm in ENVI software to observe land-use changes from 1995 to 2015, using Landsat Thematic...
The purpose of the experimental study is to investigate the effect of earthen channel geometry on erosion by runoff. After the construction of an experimental setup, four geometric shapes were tested; the circle, the triangle, the sinus and the trapeze. These four forms were dug in agricultural sandy-loam soil. For all experiments, and for each geometric shape, discharge, slope inclination, time,...
Coffee grounds (CG) improved some soil physical properties (dry density, gd; porosity, n; aggregation; hydraulic conductivity, Ks; and infiltration rate, IR). Effects on other properties were inconsistent (e.g., sorptivity, S), or unfavorable (e.g., available water, AW). gd decreased and n increased with CG. CG decreased Ks in sand. In calcareous soil, maximum increase was associated with 10% and...
Waste disposal in landfills is one of most frequently used methods of municipal solid waste (MSW) management. Landfills disturb to a certain extent the landscape character and disposal of waste in landfils represents one of human activities that may impair natural ecosystems. Due to waste decomposition, numerous chemical, physical and biological reactions and changes occur within the landfill body...
The aim of this research was to find the relationship between metals content and age of the sediment and to estimate the contamination level. For the research of sediment, samples were taken from the glacial Lake Prokosko. Concentrations of eight elements (Ca, Mg, Fe, Cd, Pb, Zn, Cu and Mn) were determined. The age was determined with usage of C14. For statistical evaluation of the results, we used...
The aim of the study was to determine the type and origin of plant communities on an area of 4 lysimeters (35 m2 each) filed with ash and covered with two superlayers 12 years after the beginning of the experience. The paper presents the species of grasses sown in 2003, their sward participation then and the flrist status in 2015. Phytosociological records were taken using the Braun-Blanquet’s method,...
Two different approaches to assess and map the potential of regulating agroecosystem services have been used, the assessment of the potential of regulating agroecosystem services based on a composite index and the assessment of the potential of individual regulating agroecosystem services were used in the Krupina study area. The overall composite index indicates a general overview of the performance...
Soil fertility evaluation has been considered as a most effective tool for sustainable planning of a particular region. This study was conducted to determine the soil fertility status of the Agricultural Research Station, Pakhribas, Dhankuta, Nepal. The total 60 soil samples were collected randomly at a depth of 0-20 cm by using the soil sampling auger. For identification of soil sampling points A...
In this paper, the influence of metals (Cd, Pb, Cu, Co, Ni, Zn) on plants of spring barley (Hordeum vulgare L.) was investigated in polluted sod podzolic sandy loam on layered glacial sands and calcareous deep chernozem on loamy loess soils. We propose to highlight the metals’ phytotoxicity with help of the phyto maximum allowable concentration. The Phyto Maximum Allowable Concentration is a permissible...
