부식산을 포함하는 생육활성촉진제가 잔디 및 수목 생육에 미치는 영향

Application of biostimulants, humate-based products marketed as aids to plant establishment, may increase root growth of turfgrass and maple tree. We tested three types of biostimulants on root growth of creeping bentgrass (Agrosfic palustris Huds.) and maple (Acer rubrum L.). Roots were first observed in the 2-3 weeks after treatments. Biostimulant-treated tufgrass and tree had more root length than nontreated controls. Turfgrass nutrient absorption was increased with biostimulant application.
