Olives

 The Organic Olive Production Manual addresses all aspects of olive production in an organic context. An overview of site selection, olive cultivars and the economics of olives as a commodity provides background. There are chapters devoted to all the important elements of olive orchard culture that are specific to organic production: nutrition, weed control, disease prevention and insect pest management including olive fruit fly. Composting and olive waste management are detailed as part of the sustainable system. Agroecological principles for making the conversion to organic olive production and information about organic certification complete the manual. Available at ANR publications website.
