Laboratory and lysimeter studies of glyphosate and aminomethylphosphonic acid in a sand and a clay soil.
Due to the increasing concern about the appearance of glyphosate [N-(phosphonomethyl)glycine] and its major metabolite aminomethylphosphonic acid (AMPA) in natural waters, batch laboratory and lysimeter transport studies were performed to assess the potential for leaching of the compounds in two agricultural soils. Unlabeled and 14C-labeled glyphosate were added at a rate corresponding to 1.54 ...
متن کاملEffect of Soil Application of Humic Acid and Fluvic Acid on Agronomic traits of Barley
One of the most important issues affecting environmental health and sustainable food production is application of organic fertilizers instead of chemical fertilizers. This study set out to investigate the effect of application of soil humic acid and fulvic acid on barley plant. To this end a factorial experiment was carried out on the basis of randomized complete block design with four replicat...
متن کاملClay transformations following a leaching experiment on an acid brown soil
Detailed studies on soil processes commonly involve the use of reconstructed soil columns (e.g. James & Riha, 1989; Liu et al., 1990; Smith et al., 1995). This approach reduces the inherent variability associated with field experiments, allows the simultaneous monitoring of solution and solid phases, and limits the interactive effects from concomitant processes. Sample pretreatment (airdrying, ...
متن کاملSorption and Desorption of Pesticides by Clay Minerals and Humic Acid-Clay Complexes
small amounts of water to soil reduced the sorption of organic compounds relative to the sorption by the In soils, organic matter and minerals are often associated such that dehydrated soil in hexane, and that organic vapor adit is unclear how the presence of the former component influences sorption by soil was significantly depressed by increasing the sorptive properties of the latter one. In ...
متن کاملDesorption of arsenic from clay and humic acid-coated clay by dissolved phosphate and silicate.
Arsenic (As) contaminated aquifers contain iron minerals and clays that strongly bind As at their surfaces. It was suggested that As mobilization is driven by natural organic matter (including fulvic acids (FA) and humic acids (HA)) present in the aquifers either via providing reducing equivalents for reductive dissolution of Fe(III) (hydr)oxides or via competitive desorption of As from the min...
