Claim Text:
1. A solid, porous weed barrier: wherein the solid barrier is formed by spraying an aqueous solution of nonwoven fiber macroscopic particles and polymer binder; wherein the solid barrier contains pores ranging in size between about 0.01 mm and about 1 mm; wherein the pores of the solid barrier are formed after contacting the aqueous solution with soil and allowing the aqueous solution to solidify by curing under ambient conditions; wherein the microscopic particles in the solid barrier form a random orientation of fibers; wherein the microscopic particles have an average length of between about 100 microns and about 1000 microns; wherein the barrier contains no visibly apparent voids or holes; and wherein the formed barrier is sufficiently solid to be a physical barrier to weed growth and sufficiently porous to allow water to penetrate through the solid barrier.
