Abstract
(EN)
Disclosed are: a biodegradable coating composition for a mulching paper; and a mulching paper. Out of these, the biodegradable coating composition for a mulching paper comprises: 45-72 parts by weight of spring water, the spring water being made by immersing a mineral material powder, which has a particle size distribution of 400-700 mesh and includes a sericite powder, in water contained in a container for 10-20 days to thereby allow mineral components of the mineral material to dissolve in water; 3-8 parts by weight of a charcoal powder having a particle size of 1,000-3,000 mesh; 8-13 parts by weight of a calcium liquid; 5-15 parts by weight of a filler containing a sulfur powder, an illite powder, and an expanded vermiculite powder; 5-8 parts by weight of starch; and 10-20 parts by weight of an additive.
