Abstract:BACKGROUND
The environmental risk of the application of synthetic chelates has furthered the implementation of biodegradable complexes to correct manganese (Mn)‐deficient plants. This study used the biodegradable ligands of heptagluconate (G7) and gluconate (G6) to test the influence of the Mn2+:ligand ratio on their fertilizers' capacity to provide Mn to plants. The efficacy of these complexes to correct Mn‐deficient soybean was evaluated in hydroponics and calcareous soil conditions and compared with the syn… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
