California Rice Grower Demystifies Rice Industry

California Rice Grower Feeds Minds Also

By now, growers have harvested much of northern California’s rice. Most of it is already in the rice mill. While prices were low this year, production has been very good, according to Matthew Sligar, a third-generation rice grower in Gridley, up in Butte County.

“Yes, we just got done with rice harvest. We are chopping the rice straw that is left in the fields. We’re disking it in to aid in decomposition,” Sligar said.

“Then we flood the fields with about 4 to 6 inches of water, creating a natural habitat for migratory birds. We just let the field sit over the winter so the straw decomposes. We work it back up in the spring.”

Northern California rice growers dedicate the winter months, and even the early season months when fields are first flooded, to help migratory birds whose original habitat has been taken over by cities and expanding neighborhoods.

Birds by the millions – including ducks, geese and shorebirds – rest, feed and rear their young in rice fields during their annual migrations. “Our fields turn white like snow from the down floating feathers left behind by birds,” Sligar said.

And yet, due to global oversupply, rice prices are trending lower this season. “We had to put our rice into a marketing pool because we wanted to guarantee a home for it,” Sligar said. “We did not want to gamble on the cash market. We haven’t seen the returns yet; however, I got a great yield, and I hear most of Northern California got extremely good yields.”

“Hopefully, that will make up for some of the low price, and we might make some money. When you get a good year, you’ve got to save that money for bad years like this year, just make it through to next year,” Sligar said.

Besides farming rice, Sligar is a cyclist and a social media blogger. He produces great videos on all segments of the rice industry.

“That’s one reason why I started Rice Farming TV because whenever I’d be at a restaurant or some spot socializing, someone will say, ‘What do you do?’ I tell them that I farm rice. ‘Rice? Where do you live?’ I say, ‘I live in California.’ They don’t know that rice is grown in California, but it’s the best,” Sligar said.

Earthworms Help Cleanse Dairy Wastewater

Fresno State has turned to a group of very efficient workers to help clean up wastewater on the campus dairy.

Red earthworms now play a big role in the effort to solve water quality challenges. They squirm when you interrupt their meal. 

The worms dig in and feast on wood shavings soaked in wastewater from cow manure.

Sanjar Taromi is the chief marketing officer for BioFiltro. He explained, “The wood shavings absorb a lot of the organic contaminants within the wastewater. The worms then eat that material depositing their castings.”

The Chilean-based company relies on worms to do their dirty work for the pilot project at Fresno State. 

Taromi said, “We’re also taking analysis of wastewater to show to reductions in key indicators like nitrates and nitrogen, phosphates.”

Taromi added the campus dairy uses over 25,000 gallons of water each day. This system filters about 15 percent of the wastewater. “Water is turned on and it comes and flushes the lanes down and carries the manure down to the solid separation basins.”

The water which came out of the cow stalls was a murky dark brown. After the bio-filtration process the water was a lighter brown color but Taroma says that was due to the wood shavings. As the worms turn they produce a cleaner, recycled product.

Taroma said, “You have irrigation water that now you can use with drip irrigation, with center pivots.”

Dairy wastewater is normally only used for flood irrigation on crops used for feed.
