World Alfalfa Congress to be held in San Diego, California, USA 14-17 November 2022

Hay and silage farmers, scientists, and forage industry professionals from around the world will gather in San Diego, California this November for a four-day session to talk all things alfalfa. The purpose of the World Alfalfa Congress is to share knowledge, new research data, and industry trends this important crop. 

Alfalfa is one of the most important forage crops in the world and the fourth most valuable field crop in the United States as of 2022. Alfalfa is a crucial part of the agricultural landscape, as it is grown on over 16 million acres in the US and is important in many other countries. World trade in alfalfa hay has increased in recent years, with a strong interest in Asia, Europe, North Africa, and the Middle East.

The Congress is co-sponsored by a wide range of organizations from around the world: National Alfalfa & Forage Alliance (NAFA-US), California Alfalfa & Forage Association (CAFA-US); UC Davis (US); USDA-ARS (US); China Grasslands Association (China); China Alfalfa Industry Association (China); INRAE (France); INTA (Argentina); CIDE (EU); China Agricultural University (Beijing); and AEFA (Spain).

Program topics include economic and ecological importance of alfalfa, genetics and breeding, agronomic practices, exports, soil fertility, weeds, pests and diseases, forage machinery, new uses, forage quality, equipment, irrigation, water, and environmental aspects.

The Congress features a one-day training on pest management and irrigation for practitioners, as well as two days of technical presentations. The program also features a full day touring the Imperial Valley, an important alfalfa-growing area in Southern California. The tour will feature year-round alfalfa production, irrigation methods, research plots, hay and seed exports, environmental issues, winter vegetable production, and equipment displays.
