Abstract
A sod comprising a root support matrix that itself comprises a mixture of soil and/or sand and shredded carpet pieces has a beneficial plant adjuvant disposed on the shredded fabric pieces, preferably in the form of shredded carpet pieces. The beneficial plant adjuvant is initially suspended in an aqueous solution of water and a degradable, slow-release, water-soluble liquid polymer that when dried forms a coating on the surface of the shredded carpet pieces.
