Testing MACRO (version 5.1) for pesticide leaching in a Dutch clay soil.
Testing of pesticide leaching models against comprehensive field-scale measurements is necessary to increase confidence in their predictive ability when used as regulatory tools. Version 5.1 of the MACRO model was tested against measurements of water flow and the behaviour of bromide, bentazone [3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one-2,2-dioxide] and imidacloprid [1-(6-chloro-3-pyridylm...
متن کاملChanges study of soil splash and stability of soil aggregates using polyvinyl acetate
Soil erosion, especially water erosion, threatens the installations, water resources and also human life. The first stage of water erosion is the splash erosion that it requires to control in the primary stages. On the other hand, the application of soil conditioners is one of the approaches that it provide the conservation possibility of soil surface against water erosion, especially erosion f...
متن کاملElectric Alignment of Plate Shaped Clay Aggregates in Oils
We experimentally investigate the rotation of plate shaped aggregates of clay mineral particles immersed in silicone oil. The rotation is induced by an external electric field. The rotation time is measured as a function of the following parameters: electric field strength, the plate geometry (length and width) and the dielectric properties of the plates. We find that the plates always align wi...
متن کاملQuality evaluation of processed clay soil samples
INTRODUCTION This study assessed the microbial quality of clay samples sold on two of the major Ghanaian markets. METHODS The study was a cross-sectional assessing the evaluation of processed clay and effects it has on the nutrition of the consumers in the political capital town of Ghana. The items for the examination was processed clay soil samples. RESULTS Staphylococcus spp and fecal col...
متن کاملPesticide sorption and diffusion in natural clay loam aggregates.
Pesticide sorption in soils is controlled by time-dependent processes such as diffusion into soil aggregates and microscopic sorbent particles. This study examines the rate-controlling step for time-dependent sorption in clay loam aggregates. Aggregates (5 mm) were stabilized with alginate, and adsorption of azoxystrobin, chlorotoluron, and cyanazine was measured in batch systems equilibrated f...
