Study on Productive Effects of RE Applied to Fine Perennial Grasses and Legumes

Rare Earth (RE) is one of very important growing promoter in forage production, which can promote seed germination, plant growth and nodule bacteria proliferation in certain concentrations. Of all RE concentrations, 500 mg/kg is is most suitable to grasses production and can increase biomass by 7.5%; 500-600 mg/kg are most suitable optimum range for RE promote legumes production and rise biomass by about 7.2%. Seed-soaking is best for forage production in all three RE application methods.
