EFFECTIVENESS OF LEGUME SEEDING FOR EROSION CONTROL. FINAL REPORT

The materials historically used for erosion control have required high inputs of fertilizer to obtain a cover. That cover provided abundant fuel for fires, delayed the invasion of desirable plants and often did not persist. Legumes, in association with rhizobia, have the ability to produce their own nitrogen. As erosion control covers, they refertilize sterile construction site soils, help reestablish soil profiles and allow the invasion or reestablishment of desirable woody vegetation. They can also produce sufficient biomass to provide surface erosion protection. This research project reviews the use of legumes for erosion control on Caltrans projects, problems of inoculation and nodulation, pellet inoculation, preinoculation, hydroseeding of legumes and fertilization practices.
