METHOD OF USING AGRICULTURAL MULCHING FILM

摘要

PROBLEM TO BE SOLVED: To provide a method of using an agricultural mulching film for not merely saving labor of farm work but also reducing load to the environment. SOLUTION: This method of using the agricultural mulching film comprises using a film obtained by formulating a resin component comprising a polymer (A) mainly made from diol and dicarboxylic acid and a polymer (B) made from oxycarboxylic acid with calcium carbonate (C) so as to have desired biodegradability and photodegradability, and plowing film pieces in soil after a given period expires.
