Abstract:At trace concentrations, selenium (Se) has been shown to exert positive effects on plant growth, but Se essentiality to higher plants remains in doubt. Plants can absorb Se from the soil in inorganic or organic forms, but the cycling and bioavailability of organic Se in the manure-soil-plant system remain to be fully understood. This study investigated the effects of pig manure composting on the growth and Se accumulation in Lolium perenne L. (cv. Riikka) at different growth stages. A pot experiment with silic… 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.
