Abstract
The present invention relates to an agricultural mulch made from a fibrous cellulosic web having a certain breaking length and which had been surface-coated with a latex coating to improve wet strength and handling properties. The material of the present invention, once formed, is particularly suitable for use in agricultural applications to control weeds, soil moisture and temperature. The mulch can be engineered to have useful life which will correspnd to the growing cycle of a specific crop. Unlike plastic, once the crop has been harvested, the material of the present invention is much more suitable for composting due to the degradable nature of the product.
