Biodegradable mulch films (according to the biodegradability criteria defined in the Delegated Regulation 2024/2787 of 23 July 2024) are included in the FPR as SOIL IMPROVER (PFC 3), and in particular as INORGANIC SOIL IMPROVER (PFC 3B). A soil improver is defined as „an EU fertilising product, the function of which is to maintain, improve or protect the physical or chemical properties, the structure or the biological activity of the soil to which it is added“. CE marked soil-biodegradable mulch films fulfill the requirement of SOIL IMPROVER, due to their characteristics of use: while they improve soil temperature and humidity during their use, once incorporated, they add organic carbon to the soil, which stimulates the microbial community.
