Abstract
Disclosed is a sprayable nonwoven fiber weed barrier comprising an aqueous solution of nonwoven fibers and polymer binder. The aqueous solution can be directly sprayed onto the soil to suppress weed penetration through the soil. The sprayable nonwoven fiber weed barrier has a pore structure that allows water to penetrate into the soil, but curbs the growth of weeds.
