Manure and Soil Health

This page provides resources from roundtables, webinars, presentations and publications regarding manure and soil health.

RESource	Description
Manure and Soil Health Roundtables	The Soil Health Nexus held four soil health and manure virtual roundtable discussions in 2017 featuring subject-matter experts, farmers, consultants, and producer-led groups sharing research, trends and experiences. The presentations focused on Manure and Soil Health Testing; Manure and Soil Biology; Manure and Soil Erosion, Runoff and Losses; and Manure and Cover Crops.
Webinar: Using Manure to Improve Soil Health	This webinar looks at current practical research in South Dakota and Michigan related to manure use as it relates to soil health. This presentation was originally broadcast on March 1, 2019 on the Livestock and Poultry Environmental Learning Community Webinar Series.
2019 Waste to Worth Manure and Soil Health Proceedings	Waste to Worth brings together the nation’s best science on animal agriculture and the environment. Presentations and their respective proceeding papers include innovative research and outreach and focus on several areas related to soil health. This is only a portion of the Waste to Worth 2019 proceedings. The remainder are available on the Livestock and Poultry Environmental Learning Community’s website.

Extension Publications exploring the relationship between soil health, water quality and manure.	The Soil Health Nexus funded as series of mini-grants through the 2016 Manure and Soil Health Working Group. As a result of this work four reports exploring the relationship between manure, soil health and water quality were released in September 2017. Manure Land Application and Soil Health Indicators This report and data-brief summarizes the effects of manure on soil health characteristics by correlating data on soil health related variables and manure land application details connected under the Missouri Cover Crop Cost-Share Program. Synthesis of Studies Reporting Soil Quality Metrics Under Agricultural and Municipal Biosolid Applications This report and data-brief summarizes and interprets short and long-term studies on the effect of manure and municipal biosolids on soil properties. Winter Manure Application: Management Practices and Environmental Impact This report and data-brief summarizes the state-of-the-literature on on winter manure application with regard to existing contaminants of concern, case studies, existing best management practices, state level policy, and the efficacy of present management systems. Winter Manure Application: Research needs, future direction and literature review As a supplement to the winter manure report and data-brief researchers created a document summarizing relevant winter manure studies and a report summarizing research needs and the future direction of winter manure science.
