Viticulture Library

What is the Library?


Welcome to the Lodi Winegape Commssion’s Viticulture Library. The Library is meant to be a user-friendly resource for accessing practical and scientific articles about vineyard managment. The Library includes a searchable database of hundreds of articles organized into a number of categies. Click HERE for a list of categories. The Library houses a wide range of articles from cutting-edge research to early publications to dating back as late as the 1960′s. The Library is a living resource, meaning that new articles are added frequently. If you have an article that would make a good addition to the Library, please send it to Matthew Hoffman at

How does one use the Library?

Using the Library is simple. The search engine recalls articles by title, author, year of publication, and topic. Simply type a key term into the search field, and click “Search”. For example, if I am interested in learning more about soil nutrition, I might search for “nitrogen” or “compost”. If I am interested in learning about how to control a specific pest, I could search for “bunch rot” or “botrytis”. Searching for “Paul” or “Verdegaal” would retrieve all articles on record authored by our UCCE county farm adviser. If you don’t find what you are looking for with the first search, try using a more general or more specific term. For example, if “ammonium sulfate” does not work, try “soil fertility”. If “mechanization” does not work, try “box pruning”. Don’t be afraid to experiment. Once you find an interesting article, you can read it online or download it as a PDF (drag your cursor to the bottom right of your screen and a download promp will pop-up.
