Depending on your location, cover crops can have a big impact on your fields. Steve Haring, second-year Ph.D. student in the Department of Plant Sciences at UC Davis, has been collecting research on how different climates influence the effectiveness of cover crops.
“As we try to design cover crops, there are a lot of different paths we can take, and it’s important to test these different things out and see what is best for the specific things we can use cover crops for in the Central Valley,” Haring said.
He further mentioned that for optimum weed control in the Valley, growers should plant in the early winter months in order to prevent annual winter weeds.
Haring worked with the UC Davis Cooperative Extension on three different sites across both the Central Valley and northern Sacramento Valley collecting data on growth rates for cover crops. He found that because the northern valley had more direct sunlight hit the ground, cover crops thrived, and as a result, weeds were minimized.
The research will not stop there, though, Haring ensured. “The study I’m working on is funded by the Almond Board, and it’s continuing for a second year and maybe a third, so we’re trying to repeat it and validate and then also sort and synthesize information because there are people working on weeds but also working on water, insect pests, pollinator health, nematodes, and call sorts of ecosystem services,” he concluded.
“It raises this question,” Peltier asked, “When do we get honest and start talking about the regulatory drought—the man-made drought, the policy-induced drought, the policy-directed drought? We can’t even have an honest conversation about that.”
“That our opponents want to deflect and obscure that whole conversation is telling,” he continued, “because we have a tremendous story of adverse economic impact as a result of failed policies. When they tried to protect the fish, they took our water away and they made the supply unreliable. ‘Just a huge failure and they don’t want to address it; they don’t want to deal with it. The same agencies are fixated with their false confidence or their false certainty, their false precision, in terms of how to help the fish.”
Peltier explained the regulators failed to deliver all of the 5% allocation [née water delivery reduced by 95%] to growers in the federal water districts south of the Delta. “It’s nonsense,” he reiterated, that part of the insufficient 5% was never delivered this season. “It’s avoidance of the reality that the regulators have constricted the heck out of the water projects and made it so—even in wet years, and like this year, a normal to wet year—we’ve got huge amounts of land out of production,” Peltier said, adding that almond growers in the federal water districts are not getting a late, post-harvest irrigation, which can hurt next year’s production.
