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...
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...
