Extracted sweet corn tassels as a renewable alternative to peat in greenhouse substrates

▶ Soilless substrates are primarily used in the production of containerized greenhouse and nursery crops. ▶ Sphagnum peat moss is a primary constituent of these substrates and its harvest from endangered ecosystems has become a worldwide concern. ▶ Ethanol-extracted, coarse-ground corn tassels were used as a peat replacement for potting substrates. ▶ This research indicates that extracted ground tassels may be utilized as a suitable replacement for peat in greenhouse substrates for tomatoes.
