Closing Remarks

Biodegradable plastic mulches represent an exciting new venture in agriculture. There are the anticipated benefits of reducing crop production costs while minimizing undesired plastic waste in the environment. The work of scientists in multiple disciplines is leading to accelerated findings regarding fabrication, microbial utilization in soil, reactions under diverse climatic conditions, impacts on crop yield and quality, and consumer acceptance. As we increase our understanding regarding the claims associated with biodegradability, agricultural scientists are able to contribute to the development of biodegradable plastic products outside of mulches, or even outside of agriculture. Future research may also focus on issues related to the risks and benefits of carbon emissions during microbial break-down, utilization of targeted microbial degraders, and accommodating organic production requirements.
