ROCHESTER (December 8, 2020)– Plastic mulch is commonly used on farms to suppress weeds and conserve water, yet it also harms the environment as it ends up in landfills. The Foundation for Food & Agriculture Research (FFAR) awarded Rochester Institute of Technology (RIT) a $779,982 Seeding Solutions grant to develop a sustainable, biodegradable alternative to plastic mulch. Empire State Development’s Division of Science,Technology and Innovation (NYSTAR) is providing $334,355 and RIT is contributing $445,827 in matching funds for a $1.56 million investment.
Plastic mulch is inexpensive and easy to install. However, these films are difficult to re-use and are often disposed of in landfills or incinerators after a single growing season. Biodegradable alternatives are available, but they decompose slowly and do not perform as strongly as plastic mulch. New approaches are needed to provide growers with economically feasible alternatives to plastic mulch that maintain long-term soil ecosystem health.
RIT researchers are developing an alternative to plastic mulch that decomposes faster and can be more easily disposed of on farms. The resulting mulch has the potential to cut costs for farmers while drastically reducing the amount of waste they produce. It could also reduce pesticide use, conserve water and increase crop yield and quality.
