149: Fair Market Trade: Arbuscular Mycorrhizal Fungi and Grapevines

<p>Arbuscular Mycorrhizal Fungi, known as AMF, has an interesting an important relationship with plants, grapevines included. AMF helps vines take up mineral nutrients, creates a layer of protection from pathogens by occupying plant cells, and seems to improve soil structure and water movement.  In turn, grapevines supply carbohydrates to the fungus. Scientists believe the pant calculates the value of giving carbon in exchange for nutrients provided by the AMF.</p> <p>Tian Tian, Viticulture Farm Advisor, Cooperative Extension Kern County, UC Cooperative Extension studies this super host relationship between grapevines and AMF to determine how farmers can cultivate this natural alliance.</p> <p>She also covers how different Nitrogen applications impact wine flavor. A winemaker can create tropical notes or clean flavors in Chardonnay through soil, foliar or winery applications of Nitrogen.</p> <h2>References:</h2> <ul> <li><a href= "https://www.vineyardteam.org/resources/resource-library/soil-conservation-and-water-quality.php?id=670"> 28: Understanding Soil Health</a></li> <li><a href= "https://www.vineyardteam.org/resources/resource-library/soil-conservation-and-water-quality.php?id=794"> 72: Soil Microbes and Nutrient Availability</a></li> <li><a href= "https://www.ajevonline.org/content/72/1/64.article-info#sec-1">Appropriate Time to Measure Leaf and Stem Water Potential (Abstract only)</a></li> <li><a href= "https://cekern.ucanr.edu/about/contact/?facultyid=46437">Dr. Tian Tian, Cooperative Extension Kern County</a></li> <li><a href= "https://www.ajevonline.org/content/early/2022/03/07/ajev.2022.21044"> Impact of Nitrogen Fertilizer or Nitrogen Wine Additions on Productivity and Sensory Outcomes (Abstract only)</a></li> <li><a href= "https://www.winebusiness.com/news/article/257169">Managing Nitrogen in the Vineyard and the Winery Efficiently</a></li> <li><a href= "https://www.sipcertified.org/get-certified/self-assessment/">SIP Certified</a></li> <li><a href="https://www.sustainableagexpo.org/">Sustainable Ag
