Seeding POLLUTANTS ADDRESSED: Sediments
DESCRIPTION: Seeding is used to establish forage species and to apply an herbaceous seed mix to disturbed areas. Methods of seeding include broadcasting, mulching, hydro seeding and aerial seeding.
ADDITIONAL BENEFITS: Production of a forage crop Seeding nitrogen-fixing species can add nutrients to soil
POTENTIAL TREATMENT AREAS: Agricultural Lands Developed Lands Streamside
LOAD REDUCTION MECHANISM: Sediment Reduction – Plant roots protect the soil from erosion, reducing sediment input to streams.
ALTERNATIVE MANAGEMENT MEASURES: Exotic Removal Erosion Control Fabric Mulching Tree Planting
LAND USE CLASSIFICATION: Construction sites Agricultural lands Grazing lands Mining lands
PERMITTING REQUIREMENTS: None
