The report, published in Hort Science, was the first peer-reviewed study to evaluate EDDS as a chelating agent in fertilizers used on a horticultural crop, Albano says.
There have yet to be any reports on the systematic study of the distribution of trace elements in the leaves of soy plants during their flowering (vegetative) stage that have been treated with various organic chelating agents. The chelating agents that were applied include Citric acid, Disodium EDTA (DSEDTA), Salicylic acid, and also the combination of those chelating agents with Fe[Cl.sub.2] which were tested on eight groups of soybean plants.
The category of clarifiers contains products such as flocculants and chelating agents. Though using different chemical processes, both essentially help to bind solids together, according to NSPI's glossary of industry terms.
