Nonpoint source pollution from construction sites and roadsides is a major problem throughout the United States. Estimates of soil lost from construction sites can be 20 times greater than agricultural erosion, resulting in the deterioration of our lakes and streams. To address this problem, several types of mulch-mats have been developed that provide effective erosion control, most recently, kenaf. Preliminary research by the USDA Forest Products Lab, has shown that kenaf bast fibers can be blended with other non-wood fibers and used successfully as a matrix for mulch-mats in tree nursery establishments. Kenaf has unique fiber properties, one of which is the absorption of water up to 10 times its weight. Federal legislation adopted in 1987 requires that 25 cents of every $100 used in Federal Highway landscaping be used to plant native species on roadsides. Establishment of these native plants have been difficult for many practical reasons including lack of knowledge about management of native plants, lack of available seed sources and competition from cool season grasses. The objective of this research is to determine the effectiveness of kenaf mulch-mats as an improved erosion eontrol product and as a new method for establishing native plants.
Anticipated Results:1. Develop a new technology using kenaf as a staple fiber in a non woven, air laid needle punched mulch-mat. 2. Determine the feasibility of blending native plant seeds into a kenaf mulch-mat and evaluate its effectiveness and potential for commercialization. 3. Evaluate the effectiveness of kenaf mulch-mat for erosion control on roadside. 4. Foster new agricultural crops (kenaf and native plants) benefitting Wisconsin's farmers, agricultural industries, and its rural communities.
