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, ...
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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
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 ...
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 ...
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 ...
