3D Discrete Element Model to Describe the Draft Force and the Influences of the Tool Geometry
Virtual DEM models were developed in correspondence with the real tests. In this article we will introduce the methods of how DEM approach was used in developing a model for the prediction of draught force on cultivator ... -
Determination of Atrazine, Acetochlor, Clomazone, Pendimethalin and Oxyfluorfen in Soil by a Solid Phase Microextraction Method
A solid phase microextraction (SPME) method for simultaneous determination of atrazine, acetochlor, clomazone, pendimethalin and oxyfluorfen in soil samples was developed. The method is based on a combination of conventional ... -
Effects of Irrigation on Yield and Composition of Principal Elements of Nutrients in Maize-Growing Soil
Extensive organic production under irrigation conditions requires greater amounts of NPK fertilisers. Furthermore, the mobility of fertilisers, especially of nitrogen, is greater under the increased soil moisture content, ... -
Effects of Metribuzin on the Activity of Some Enzymes in Soil
Eeffects of metribuzin on the activity of some enzymes in soil was investigated. Trials were set up in the laboratory on a clay loam soil. Metribuzin was applied at 12.0, 24.0 and 60.0 mg/kg soil rates and soil samples ... -
Effects of Organic Matter and Clay Content in Soil on Pesticide Adsorption Processes
The effect of organic matter and clay content on the adsorption of atrazine, acetochlor, clomazone, pendimethalin and oxyfluorfen in soil samples was studied. In order to determine whether and to what degree different ... -
Methods for Determination of Pesticide Adsorption Properties and Examination of Their Mobility in Soil
Pesticide destiny in soil depends on a number of factors, as well as on presence and intensity of the processes such as adsorption, degradation, evaporation, rinsing and leaching. Since adsorption processes govern ... -
Methods of Imazethapyr Extraction from Soil and Cleaning up by Solid Phase Extraction
The aim of this work was to optimize the determination methods of imazethapyr residues in soil using HPLC with DAD and C 18 (Hypersil ODS, 5 ìm, 2.0 x 250 mm) columns and to find the most appropiate solvent for imazethapyr ... -
Multiresidue Analysis of Pesticides in Soil by Liquid-Solid Extraction Procedure
A multiresidue method for simultaneous determination of four pesticides (diazinon, acetochlor, aldrine and carbofuran) belonging to different pesticide groups, extracted from soil samples, is described. The method presented ... -
Pesticides in Soil: Effects on Microorganisms
Since their discovery to the present day, pesticides have been an inevitable segment of agricultural production and efforts have been made to synthesize compounds that would share a required efficacy along with selectivity, ... -
Pomological Characteristics of Wild Cherry Genotypes (Prunus Avium L. /Moench/) From Potkozarje Population
This paper presents the results of the investigation of wild cherry (Prunus avium L. /Moench/) population in the area of Potkozarje. The studied genotypes grow in association with sweet chestnut (Castanea ... -
Potentials of Rapeseed Crop Residues in Serbia
Rapeseed straw is potential source of renewable energy, but important source of soil organic matter as well. The amount of crop residues, available for energy use, per hectare, is not well known. Excessive offtake of crop ... -
The Processes that Determine the Fate of Pesticides in Soil
Pesticides are an inevitable part of the environment, because due to the intensive use their remains are frequently detected in nature, particularly in the soil. Regardless the way pesticides get into the soil, their ... -
Soil Moisture Influence on the Energy of Agricultural Processes
This article exposes the results related to one of the issues left open after a series of articles mentioned in the bibliography, which occurred in the years 2011-2013. A series of articles that were mentioned before ... -
Solid Phase Microextraction (SPME) in Determination of Pesticide Residues in Soil Samples
The basic principles and application possibilities of the methods based on solid phase microextraction (SPME) in the analysis of pesticide residues in soil samples are presented in the paper. The most important experimental ...
