Research team collaborates to examine animal-based soil amendments

WASHINGTON, Sept. 28, 2016 /PRNewswire-USNewswire/ -- A new $2 million grant from the U.S. Department of Agriculture (USDA), awarded to a multidisciplinary team from the University of California, Davis, University of Minnesota, University of Maine, the USDA Agricultural Research Service's Beltsville Agricultural Research Center, USDA's Economic Research Service Resource and Rural Economics Division, the Produce Safety Alliance, and The Organic Center, will address one of the most pressing issues for the organic community—how to use manure effectively in organic farming in ways that foster healthy soil and minimize risks to food safety. 

Announced on Wednesday by USDA with funding provided by its Organic Agriculture Research and Extension Initiative (OREI), the grant (exact amount $1,999,848) will support research examining the relationship between manure use in improving soil health and food safety, concentrating on organic fresh produce production. 

The new grant implements a research plan developed by UC Davis, The Organic Center, and the Organic Trade Association (OTA) during their 2016 OREI planning grant.  The long-term goal of the project is to provide critical information for guidelines on risk mitigation of foodborne pathogens for organic and sustainable agriculture.

"With this grant, we can now engage in specific research using the knowledge base that we've built, and The Organic Center welcomes our role in helping to get the word out about this vital issue," said Dr. Jessica Shade, Director of Science Programs at The Organic Center.

The impetus for these grants has been the ongoing implementation process of the Food Safety Modernization Act (FSMA) by the U.S. Food and Drug Administration to improve food safety. In new rules implementing the FSMA regulations, changes were proposed relating to the use of compost and manure and the required interval that untreated manure could be applied and crops harvested. This is of particular importance for the organic sector, as many certified organic producers rely on animal-based soil amendments such as manure and compost to improve soil fertility and quality instead of chemical fertilizers.

Several studies have shown that the use of manure and compost has multiple positive environmental impacts: increased soil health, higher soil biodiversity and reduced erosion. The improved soil health and microbial diversity in organic soils have the potential to control the presence of soil pathogens, which can impact food safety. But little research has examined the specific wait periods between manure application and crop harvest required to control pathogens, and how pathogen presence interacts with heathy soil.

"By developing an innovative, customized risk-assessment based on good agricultural practices used within the organic industry related to raw manure and soil health, the project will benefit organic farmers and consumers by providing strategies to maintain the value of raw manure soil amendments while limiting food safety risks," said Professor Alda Pires, one of the team's principal investigators from UC Davis.

The Organic Center's mission is to convene credible, evidence-based science on the health and environmental benefits of organic food and farming and to communicate the findings to the public. The Center is an independent non-profit 501(c)(3) research and education organization operating under the administrative auspices of the Organic Trade Association.
