Kresoxim-methyl, a new broad spectrum foliar-applied strobilurin group of fungicide, undergoes rapid transformation in soil to form acid metabolite. In this paper, adsorption-desorption, leaching and persistence behaviour of kresoxim-methyl and its acid metabolite in Delhi (Inceptisol) soil has been investigated. The adsorption studies were carried out at initial concentrations of 1.5, 1, 0.8, ...
In this work, we present as investigation of chalcopyrite leaching under different leach conditions for how liquidation and surface of chalcopyrite study using Scanning Electron Microscopy (SEM) to determine the composition of the passivation layer in the surface of chalcopyrite. The study of chalcopyrite dissolution were in H2SO4 solution systems at pH of 1.2, with 5% chalcopyrite concentrate ...
Effect of Leaching on Reducing the Phytoxicity of Some Medicinal Plants on Wheat (Triticum aestivum)
The aim of this study was to investigate the effect of leaching on the reduction of soybean (Glycin max), black cumin (Nigella sativa), dill (Anethum graveolens) and dragonhead (Dracocephalum moldavica) residues allelopathy in wheat (Triticum aestivum) cropping. The experiment was conducted in a completely randomized design with three replications in 2017. The factors consisted of four types of...
Accurate assessment of the fate of salts, nutrients, and pollutants in natural, heterogeneous soils requires a proper quantification of both spatial and temporal solute spreading during solute movement. The number of experiments with multisampler devices that measure solute leaching as a function of space and time is increasing. The breakthrough curve (BTC) can characterize the temporal aspect ...
