Straw Mulch and Crimped

Lavicka Works, Inc. has been involved in many projects that have specified straw mulch and or crimping. Straw mulch is the application of straw as a protective cover over seeded areas to reduce erosion and aid in re-vegetation or over bare soils that will be landscaped later to reduce erosion.

This method is used on slopes which have been seeded and have high potential for erosion. It requires some type of anchoring by matting, crimping or other methods to prevent blowing or the washing away of seed. Straw mulch forms a loose layer when applied over a loose soil surface. The mulch should cover the entire seed or bare areas. The mulch should extend into existing vegetation or be stabilized on all sides to prevent wind or water damage which may start at the edge.

Straw mulch is installed on a gentle to moderate slopes, straw mulch can be applied by hand broadcasting to a uniform depth of 2-3 inches. On steep slopes, the straw should be blown onto the slope to achieve some degree of cover. When slopes are too steep to crimp we will spray a 50 percent slurry of hydro mulch onto the straw mulch to tackify. This will assist the straw from blowing away. When applied properly, approximately 20-40 percent of the original ground surface can be seen. The application rate per care should be about 2 tons (or one 74 pound bale per 800 square feet). Straw should be clean wheat straw. In anchoring of the straw mulch we use the straw crimper. A straw crimper is an attachment that has serrated disk blades about 4-8 inches apart which forces straw mulch into the soil.
