A study by researchers from Rutgers University-New Brunswick and the University of Maine indicates that agricultural practices can help increase carbon storage in soils. Ecosystem Service Valuation Approaches and Carbon Mitigation Considerations for Garden State Agriculture says that cover cropping, grazing management, and agroforestry can increase the amount of carbon stored in agricultural soils and help New Jersey meet emissions reductions goals. In addition, these practices can help provide other ecosystem services, ranging from soil health to flood mitigation....

University of Illinois researchers studied how nitrogen in crop residues contributes to loss of soil carbon as the residue decomposes. Their trials showed that any form of nitrogen, either present in the residue or applied as fertilizer, accelerated decomposition by microbes and produced more carbon dioxide. When the residue was fully decomposed, microbes turned to soil carbon, or stable organic matter. This led to greater overall carbon dioxide production from nitrogen-fertilized residue, as well as a long-term loss of soil organic matter. The researchers plan to conduct similar testing in other soil types to see if they perform the same...

University of Wisconsin agronomy professor Randy Jackson has been exploring the potential for cropping systems to accumulate enough carbon in agricultural soils to help stabilize the climate, reports Agri-View. Jackson's 15 years of research have shown that all cropping systems studied, including crop rotations and organic rotations, lose carbon over time. Pasture systems were able to maintain carbon levels, but this reflected a small gain in the top 30 cm offset by losses below that level. "We're losing 25 grams of carbon per meter squared in the annual cropping systems when we need to be gaining between 10 and 70...

Soil health has emerged as a central theme in conversations about the future of American agriculture. Soils have become a focal topic due to new scientific understanding, the application of emerging technologies, and a growing interest among producers and policymakers in improving climate resilience and mitigating emissions. NCAT's Soil Health Innovations Conference was held online with live-streamed speakers and panels, as well as virtual halls for exhibitors and student posters. The event allowed participants to network with exhibitors and sponsors and the producers, industry professionals, educators, and students who are at the cutting edge of soil health across the country. This video...
