Whether you are in the agricultural business, have a fondness for analyzing economic data, or simply curious about agricultural and resource economics, the University of California has a site for you.
Once there you can find the most recent cost and return studies, sorted by commodity, region or county. They are interesting to look at, and certainly provide non-growers a glimpse into the amount of variables and costs associated with crop production.
There is also a link to archived studies. There you can find studies going back to 1931.
In addition to commodity studies, the site has a tree and vine loss calculator link. This link will help operators determine the value of single trees or vines lost to any cause. The calculator covers major tree and vine crops produced in California, and has a variety of input categories to cover loss from any cause.
Cost studies for California Central Coast conservation practices are also available through this site. Each of the nine studies provides an estimate of expected benefits and details on typical installation, operation, and maintenance expenses.
