Weed control

Last week I was at Nutrilite’s Lakeview farm in California. Located on a prehistoric lakebed, it’s now primarily a research farm where new plant varieties, organic farming techniques and other research innovations are tested for use on our larger farms in Washington State, Mexico and Brazil. We do grow crops there, though, and the mix includes alfalfa, pomegranates and carrots.

It’s winter now in Lakeview and that means the alfalfa fields need weed control. Weed control on a sustainable organic farm can be done a couple different ways. During the winter we use sheep.

There’s actually a shepherd that lives in the neighborhood and he transports his flock throughout the western region of the U.S. to find grazing land. But two or three times a year, from December to February, the sheep come to Lakeview. He walks them a short two miles through town to our alfalfa fields and they go to work.

A flock of 5000 sheep are fenced into a nine and a half acre field and they eat everything – the alfalfa, the weeds – right down to the nubs. When they finish there’s nothing left on the surface, except the natural fertilizer they leave behind, of course.

Alfalfa roots are strong. They extend around six feet into the soil. So when the days begin to warm again in the spring the alfalfa shoots back through the ground and flourishes, thanks to the efficient work done by a hungry flock of sheep just a few months earlier.
