PROBLEM TO BE SOLVED: To obtain a liquid mulch material which has excellent storage stability, provides a formed mulch coating film with a heat retaining property, water permeability, air permeability and prevention function of weed breeding, saves labor of mulch laying and does not need removal of the coating film after use. SOLUTION: The mulch material comprises a polymer emulsion, pigment and a humate. The mulch material comprises 0.1-40 parts wt. of the pigment and 0.1-20 parts wt. of the humate based on 100 parts wt. of the resin solid content in the polymer emulsion. The liquid mulch material has environmental loading reduced by using the biodegradable plastic emulsion. The liquid mulch material is applied to the surface of soil in a field and is laid on the surface of the soil so as to form a mulch coating film. COPYRIGHT: (C)2005,JPO&NCIPI
