Each analysis is based upon a hypothetical farm operation using practices common to the region. Input and reviews were provided by growers, UC Cooperative Extension farm advisors and other agricultural associates. The authors describe the assumptions used to identify current costs for individual crops, material inputs and cash and non-cash overhead. A ranging analysis table shows profits over a range of prices and yields. Other tables show the monthly cash costs, the costs and returns per acre, hourly equipment costs, and the whole farm annual equipment, investment and business overhead costs.
The studies for establishing orchards to produce lemons and oranges estimate costs for growing in Kern and Tulare counties. Revenue for the citrus is based on estimated sales to the fresh packaging market.
The study for organic strawberries takes into consideration growing conditions on the Central Coast of California and complying with the National Organic Program. In particular, it focuses on growing organic strawberries in Santa Cruz and San Benito counties for the fresh packaging market.
The study for producing paddy rice in the Sacramento Valley focuses on the costs of growing medium-grain rice, under a rice-only rotation in Butte, Colusa, Glenn and Yolo counties.
The field corn study focuses on the production costs of a full-season corn crop in the Sacramento Valley and the northern San Joaquin Valley. This region would include Colusa, Glenn, Sacramento, Sutter and Yolo counties. The study based costs on a farm using furrow irrigation and Roundup Ready-GMO seed.
The study on silage corn, double cropped under conservation tillage methods, focuses on production costs of corn silage using minimum tillage operations in the northern San Joaquin Valley. The corn is planted in the spring after a winter forage crop is harvested. The study is based its costs on a farm using border/flood irrigation and Roundup Ready-GMO seed.

These cost-of-production studies can be downloaded for free from the UC Davis Department of Agriculture and Resource Economics website http://coststudies.ucdavis.edu. Sample costs are also available for many other commodities. Many earlier production cost studies for agricultural commodities are also available at http://coststudies.ucdavis.edu/archived.php.
