Abstract
This invention relates to a seed dressing material for application to seeds of plants adapted to be grown in an environment with or without legume-growth-factor, to enhance the trace mineral uptake or growth of the plants. This material comprises effective amounts of fungal spores of the family Coprinus, preferably spores of Coprinus comatus, and a further ingredient selected from GTF chromium and yest, or combinations thereof. The plants resulting from the growth of seeds treated with the dressing material of this invention reach maturity faster, and have increased contents of zinc and chromium, both necessary dietary trace elements for mammals.
