Alfalfa-"Green Gold" in LA County's High Desert

The highlight of my week was visiting Farm Advisor Andre Biscaro at our Antelope Valley office in Lancaster. I went with Andre to visit one of his field trials. He is testing numerous varieties of alfalfa to see what works best in the hot, windy high desert.

Alfalfa has historically been an important crop in Los Angeles County. A 1940 Los Angeles Chamber of Commerce publication referred to alfalfa as "Green Gold", because it was considered very profitable, and listed the Antelope Valley, along with the San Fernando and San Gabriel Valleys as important production areas.

Alfalfa was traditionally grown to feed cows at the hundreds of dairies that existed in Los Angeles County. Those dairies have closed or left over the years. In fact, Andre's variety trial is on the property of what I believe is LA County's last commercial dairy. Farmer Nick Van Dam provided Andre with the space for his alfalfa variety trial, on land that had previously been used to grow onions, another important crop in the Antelope Valley.

The dairies are gone for the most part, but alfalfa is still an important crop in LA County, although it's no longer grown commercially anywhere in the county other than the Antelope Valley. According to the most recent LA County Crop Report (2007), there were 5,804 acres of alfalfa hay grown, valued at over nine million dollars. This is an interesting contrast to the 1940 LA Chamber Report which stated that 46,000 acres were grown that year, valued at $287,500.
