Mulching Polymers -- Biodegradation Weeds -- Control Agriculture
Soil-biodegradable plastic mulch (abbreviated as BDM hereafter) offers crop production benefits similar to polyethylene (PE) mulch but is designed to be tilled into the soil after use, thereby eliminating waste and disposal challenges. This publication explains the use of plastic mulch in agriculture, what BDMs are made from, and what constitutes biodegradability. It also provides information about the suitability of BDM for organic agriculture. A glossary of terms associated with the topic, adapted from Miles et al. (2015), is included before the list of references to provide readers with background information regarding plastics in general and biodegradability specifically.
