Performance Standards for Straw Mulch Binding Agents

This project proposes to determine the factors and characteristics of a variety of straw binding agents compared to emulsified asphalt, which has long been the standard practice. The two factors involved in straw mulch failure are wind and water erosion, and both will be tested. Furthermore, tests of vegetation establishment as affected by these binders will also be performed. This study will build on several recent studies on slope erosion and vegetation establishment. The study will have the following components: (1) Construct a portable wind tunnel capable of generating sufficient velocities to cause the various straw/binder combinations to fail. This will require some preliminary testing as there are no previous studies on this subject. Tests will include the straw/binder combinations under wet and dry conditions. (2) Using the portable rain simulator constructed as part of a currently funded project, test the straw/binder combinations on 2:1 slopes and sheet erosion conditions. (3) Conduct vegetation establishment studies for the most successful binders under a variety of conditions. (4) Prepare recommendations on the use of straw binders.
