MAX FACTS growing tips, news and trivia Small Avocado Groves in Peril Just 10 years ago, there were nearly 30,000 acres of avocado trees growing in such places as Fallbrook, Valley Center, Bonsall and the San Pasqual and Pauma valleys. Today that number has dwindled to between 18,000 and 22,000 acres, experts say, and the trend is expected to continue downward for the next couple years before stabilizing at around 15,000. The big farmers—the ones with groves ranging from 40 to 800 acres—will survive as they keep investing in their business by replanting for higher density and upgrading to more efficient irrigation methods. But the small guys, the ones who have a few acres of older avocados trees, are realizing that the cost of water combined with less fruit produced by their aging trees makes it financially impossible to continue.

Each of the 842 soil samples showed concentrations higher than the screening level of concern recommended by the US Environmental Protection Agency. Researchers found the patterns of arsenic in Ohio soils are most closely related to the arsenic content of the underlying bedrock formed approximately 250 million years ago. The findings should not alarm the public, say the authors, who note that regulatory levels typically are set far below those thought to be harmful. Arsenic’s reputation as a poison is warranted. High levels can cause cancer, skin diseases and death. People can be exposed to arsenic found in the soil through drinking water, the foods they eat and even through minute amounts of dirt they unknowingly ingest each day, but the element does little or no measurable harm at extremely low levels.
