Conventional Farmers Learn to Reduce Dangerous Chemicals

January 6 | Danielle Venton The fields of Henry Hibino Farms are empty. Neat rows of raised dirt stretch
along the fields, ready for the next planting.
Kent Hibino: this is more of clay loam, it’s got a higher organic matter, as
you get to the river it’s a sandy loam. 
Kent Hibino looks out on his fields from his Chevy truck. They’re bare now,
but a few weeks ago they held lettuce, romaine, celery, broccoli and
cauliflower. Kent is a third generation farmer in the Salinas Valley,
managing about 1,000 acres. And while these fields grow many of the same
crops Kent knew as a child, he’s seen some big changes since then.
Modern farming, he says, uses new techniques that let farmers apply fewer
chemicals to their land. Take, for example, the soil tests they do before a
planting. Kent sends dirt samples from each field to a lab. The lab tests for
nitrogen, phosphorous, potassium and a host of other elements. The results
inform him exactly what to apply. 
Hibino: so we’ll take a hard look at that before pre-plant and sometimes we
don’t even pre-plant because we feel everything is there, so that’s definitely
a change from my dad’s time where they were just on program, now we look
at everything field by field, what does that field need to survive.
Kent sees a slow, steady movement among farmers. Acre for acre, they’re
having less of an environmental impact now than they did 10 years ago.
Regulations are strict and pesticides and fertilizers have become expensive.
Maximizing their efficiency is all a matter of staying competitive. 
According to the California Department of Pesticide Regulation, this trend is
real, and dramatic. Between 1998 and 2009 the total pounds used of the
broad-based, more highly-regulated and generally more toxic pesticides —
things like organophosphates, for example, declined 66 percent. 
Growers now use licensed pest control officers to issue spray orders. They’ll
only recommend a spray if pests are present above certain thresholds. Many
farmers now use drip irrigation as well. This waters the plants at the roots,
and reduces the chance of mildew. Using drip irrigation, by some estimates,
allows farmers to cut fungicide use by half, and their pesticide use by a
Hibino: when you’re using drip irrigation, your spray bills will be a lot less
when you use drip irrigation, and and you can fertilize through them, not
using creating a mildewy microclimate overhead.
Farmers are also fertilizing through the drip systems. By targeting the
application they can apply less overall. And farmers switch plantings to put
organic matter back in the soil, and reduce the chance their crops will catch a
April Mackie: that’s one reason we rotate crops, if you grow lettuce,
that’s why we rotate with strawberries, reduce the number of bacteria and
viruses in the soil 
April Mackie is the Food Safety Manager for Martin Jefferson and Sons a
large, family-run operation in Castroville. Spraying costs a couple of
hundred dollars per acre so, April says, they’d rather not do it all. 
Mackie: we don’t spray just to spray, we have a guy walking the fields if he
sees a certain amount an area then he’ll know he needs to apply, it’s so
expensive, they try not to spray if they can get away with it, that’ll eat you
In this way, simply watching the bottom line is helping farmers have a
smaller footprint. For KUSP, I’m Danielle Venton. 

What Does It Take To Turn A Restaurant Green?

September 8 | Sean Rameswaram • Charlie Hong Kong is a Santa Cruz fast food restaurant that has made a number of moves to run as green an operation as possible. It recently won an award from a local environmental advocacy group for doing so. But is Charlie Hong Kong’s model practical for any restaurant?

EPA Settles Methyl Bromide Complaint, Leaves Complainants Out Of Discussion

August 31 | Sean Rameswaram • Fumigation season is approaching on the Central Coast and foes of methyl iodide are ramping up the campaign to have the known carcinogen banned. They’re taking their case to court and to Governor Jerry Brown via Facebook.

Meanwhile, the Environmental Protection Agency has made a landmark decision regarding the use of methyl iodide’s predecessor methyl bromide: The EPA found that Latino schoolchildren on the Central Coast and in Ventura County were exposed to the toxic pesticide at a greater level than their peers.

Some say the settlement is historic: The EPA has never before confirmed “adverse disparate impact” on a community in a civil rights case. But others say justice was stymied in the name of a toothless settlement that quickly closed out a complicated case.

The Monterey Bay’s Endangered Neighbors

August 5 | Sean Rameswaram • The Monterey Bay area is home to a number of endangered species. Local photographer Sebastian Kennerknecht spent the last 4 years of his life taking photos of them. He hopes his artful images will compel people to take action and help conserve species’ habitat. He gave KUSP’s Sean Rameswaram a tour of Endangered Neighbors, a collection of his work showing now at the Santa Cruz Museum of Natural History.

Cooling Coast, Warming Inland?

July 29 | Sean Rameswaram • Global warming means that temperatures across the globe are on the rise, right? Well, maybe not entirely. Some recently released numbers suggest that California’s coast may actually be cooling over time becauseof warming temperatures inland.  

Leatherback Turtles Edge Toward Federal Protection

July 18 | Sean Rameswaram • Leatherback sea turtles recently came one step closer to having part of their favorite ocean pathway recognized and regulated by the federal government. Part of that pathway is here in the Monterey Bay. 

Marine Predator Tracking Project Reveals Massive Ocean Highway

July 8 | Sean Rameswaram • Over the past ten years marine biologists across the globe were busy taking part in the first ever Census of Marine Life. One group involved in the census focused on tracking migration in the Pacific Ocean and it recently published a remarkable discovery: Marine predators, including everything from leatherback turtles to blue fin tuna, are traveling across the planet’s biggest ocean on a superhighway.

Nature Helps Crown Cowell “Biggest Beach Bummer”

June 23 | Sean Rameswaram • Summer is officially here, so we’ll be seeing many more a beachgoer enjoying the water around the Monterey Bay. A report from Santa Monica’s Heal the Bay says some of that water may not be as clean as we would like.

So, What Exactly Is Organic?

May 27 | Sean Rameswaram • Local, natural, sustainable, and organic are all terms we see on our food labels, but only one is explicitly defined. KUSP’s Sean Rameswaram spends an afternoon at the Farmers’ Market and New Leaf Community Market in downtown Santa Cruz to clear up some of the confusion surrounding “organic.” He’s joined by Amy Lamendella from California Certified Organic Farmers.
