PWTB 200-1-65 Proper Selection of Hydroseeding Mixtures and Components to Promote Rapid Revegetation of Disturbed Department of Defense Lands  


This Public Works Technical Bulletin (PWTB) provides guidance on the selection and application of hydromulch products used in hydraulically applied erosion control methods. The information is based on data collected from past studies, lessons learned from professional operators, and usage criteria from vendors. These products are a means to sow seeds over lands with a wide range of characteristics, and to provide short-term erosion control for disturbed sites and aid in vegetative reestablishment that leads to long-term erosion control. Application of the guidelines presented in this bulletin will provide personnel with the information to properly select hydromulch materials, reduce product failure due to misapplication, and reduce costs by specifying appropriate erosion control products specific to field conditions.
