This story is based on a 2013 interview, with a 2020 update.

Brendon and Sheldon Rockey are the third generation to grow potatoes on 500 acres of irrigated land in the San Luis Valley of Colorado. The Rockeys operate a farm and packinghouse near Center. Brendon is in charge of field operations while Sheldon is operations manager of the business which packs specialty potatoes for certified seed and fresh table use. The farm focuses on direct sales to commercial potato growers and the wholesale fresh table potato market. They also do some direct sales from the farm.

Brendon has successfully incorporated sustainable agriculture practices like cover cropping and companion planting into the production system to improve soil quality and conserve water. The increased soil quality that Brendon achieved with the new cropping practices improved farm profitability because he found that he could use less water and decrease or eliminate fertilizer and pesticide use while maintaining yields and improving crop quality.

Brendon Rockey says that concerns about water use on their farm pushed him and his brother into trying cover crops. Average rainfall in the valley is about five inches per year, so all agriculture there is irrigated. Growers pump from wells and that water is replaced each spring from the snowmelt, which flows down from the mountains to replenish the groundwater. During this drought, growers have been pumping more water from the aquifer than is being replaced by the snowmelt and in 2013 the aquifer level hit a record low. “Water has always been a huge issue for us out here in Southern Colorado. We’re in the middle of a drought like a lot of America, and it’s been going on now for fifteen plus years. It has really forced us to make some changes to our management practices, but it’s actually helped out our farm as a whole,” explains Brendon.

Longtime growers of certified seed potatoes as well as fresh market potatoes, the brothers decided to drop barley from their two-year potato/barley rotation about ten years ago and replace it with a mixed cover crop as a way to decrease water use. They reduced their water use by about fourteen inches, and the switch had some other significant and unexpected benefits. As Brendon explains, “Bringing in a diverse cover crop improved our soil health so much that it had a huge impact on the productivity of our potato crop.” The increase in soil quality reduced input costs and increased potato quality so dramatically that Brendon found it was more profitable to grow one cash crop every two years than one cash crop every year.

The cover crop success and the extreme drought in the Southwest has Brendon thinking about how to get even more out of his cover crops. As the drought continues unabated, Brendon is contemplating a polyculture designed to encourage beneficial insects and suppress pests in the potato crop. “We’ve seen so much positive impact from having the multi-species out in the cover crop that we are thinking about bringing more diversity into the potato crop. Next year I am planting a three-species companion crop and an eight-species insectary crop in the potatoes. I’m planting peas, chickling vetch and buckwheat in the rows with the potatoes. So I’ve got the two legumes out there for my nutrient management and the buckwheat attracting insects. I am also going to plant an occasional row of insectory mix in among the potatoes as well for the purpose of attracting predatory insects.” Brendon hopes to further reduce input costs and increase soil quality with the additional diversity added to his crop rotation.

Looking ahead, Brendon wonders about the future of agriculture in his valley. If the water supply becomes even more limited, growers will have no choice but to start taking acreage out of production. “I guess that’s the real scary thing. I’m hoping that we can get enough guys to do the right thing and save enough water that we don’t get to that point. It seems from the outside like it would be easy, but the attitude here is like, ‘I wish the neighbors would all cut back on the water so I can keep farming every acre I have.’ You just try and get a bunch of farmers together and get them to all agree on the same approach. It’s really difficult!”

Since 2013, the continuing drought in the southwest means that “water is still the number one stress factor for us in this valley,” according to Brendon. “It’s been business as usual since we talked last, no dramatic changes one way or the other in the weather.”  He has been pleased with 

Long-term drought, plus low barley prices, have encouraged more potato farmers in the region to replace barley with cover crops, a shift that both conserves water and improves the production of the following potato crop. Brendon thinks these benefits have helped to make cover crops a more common practice in in the valley.  “I’ve heard a lot of people say that even if water was no longer a concern, they would continue to grow cover crops because of the benefits to the potato crop.”

Crop diversity has continued to be a focus of Brendon’s farm management. “I cringe when I see a monoculture,” Brendon says, “because I can’t imagine that crop functioning at its peak when it’s a single species by itself. It just doesn’t make sense to me.” He has increased his companion crop mix to five species and has also expanded his insectory strip mix to more than 20 species to cultivate the long bloom time and complex plant architecture needed to support high populations of beneficial insects throughout the growing season. He has also done some recent trials to explore the potential of adding quinoa to his cash crop mix.

Perhaps the biggest change at Rockey Farms since 2013 has been Brendon’s decision to integrate cattle and sheep into his crop rotation through contract grazing of cover crops. “It’s funny when you look back, because when my grandpa started farming here, every single farmer had livestock. I’m not sure at what point we drew the line in the sand and said, ‘you can only be a farmer or a rancher,’ but it’s nice to be bringing the two components back together again because both parties benefit from it.” Neighboring ranchers appreciate the opportunity to graze their stock on high quality cover crops close to home, and Brendon appreciates the additional income from pasture rent which pays about 75% of his cover crop seed costs, plus the added soil health benefits of managed, multi-species grazing.

Looking long-term at the future of agriculture in his region, Brendon recognizes that challenges of the continuing drought, but points to the growing population along Colorado’s Front Range as a bigger threat. Thinking about the most recent attempt to pipe water from his valley to supply homes 200 miles away in the Denver area, Brendon says, “I finally decided, you know what? Climate change is not going to be the thing that ends agriculture in this valley. I am much more worried about people than I am about weather changes. It’s going to be politics and other people that will put an end to it, long before climate change will.”

Brendon and Sheldon regularly host visitors and lead workshops at their farm and Brendon is a regular speaker at farming conferences and workshops throughout the U.S. The brothers were nationally recognized in 2012 for their innovative potato production system as recipients of the Soil and Water Conservation Society Merit Award for promoting sustainable agriculture and soil health.  In 2015, the National Potato Council recognized their leadership with the Environmental Stewardship Award.

This story is based on a 2013 interview.

Jerry and Jacquie Monroe are the third generation to farm his family’s 20-acre “homeplace” in Kersey, Colorado, about an hour northeast of Denver. Monroe Family Farms is the oldest organic farm in Colorado. When Jerry and Jacquie took over from Jerry’s father in 1991, they went into the business of growing organic vegetables in a big way, adding 175 acres and starting the first CSA in Colorado in 1993, because they wanted to work closely with people who appreciated their farming philosophy. Today, the farm produces a hundred different kinds of vegetables and all the pasture, hay and feed grains needed to produce pasture-based meats (beef, pork, and lamb) and eggs on site — all of it USDA-certified organic. With the help of seven employees, Jerry manages the crop and livestock production while Jacquie manages sales and distribution for their year-around, 650-member CSA. The farm also markets to select restaurants in Denver and Boulder.

The Monroes emphasize soil health, water and energy conservation on their farm. They maintain soil health by integrating livestock into a diverse rotation of vegetables, alfalfa and feed grains. Irrigation has been upgraded from gravity-fed, furrow irrigation to more water-efficient pivot and drip systems and they use tailwater ponds to capture and return to the fields any surface runoff that occurs during irrigation or rainfall events. Produce for the winter months of the CSA are stored in dugouts, pits and straw-bale buildings, to reduce energy use. Jerry and Jacquie have succeeded with a philosophy of growing ample quantities of organic, life-filled and healthy foods while conserving and respecting the natural environment and to providing an educational experience working with Mother Nature for any CSA members who want it.

Sixteen years of extreme drought combined with higher summer temperatures, warmer winters, more extreme weather and a longer growing season have put the focus on water efficiency. “Water management has become huge,” says Jacquie. “Jerry has to keep track of how much water we have, how much he’s used. Everything has been flood irrigated here. Back in the day, they dug ditches and then had these pipes that went over the ditches and fields were just flooded to irrigate them. When you flood irrigate the top of the farm gets more water and the bottom of the farm gets less water and in the middle is the only part that gets the perfect amount of water.”

“Then we had to start conserving water because of the drought so we started putting in drip irrigation. I would say we have sixty acres of vegetables. When we first started with the drip irrigation, we put ten acres in. We’re up to probably forty acres of drip irrigation. And the rest of the crops are now under a new center pivot that we put in just this year because of the shortage of water. We want to make sure that we can continue to grow vegetables and the pivot and drip irrigation it puts that exact amount of water throughout the whole entire system. We are doing a lot more with water management. I don’t know that we would have done if our weather hadn’t changed and we hadn’t been so dry.”

Jacquie says that another change that has come with the drought has been more challenging weeds. “Weeds are starting to go crazy out here. We’re finding some of them are becoming very invasive. I can give you two examples. We’ve always had what’s called goatheads. It’s a small weed that grows very low to the ground and has a burr that sticks in your tires and in your shoes. It used to be only in certain parts of the farm, but now it seems to be going everywhere. The other one is sunflowers. We’ve never had sunflowers here before the drought. They are literally taking over all of our ditches. Anywhere that you can’t mow or get to they grow like trees and we can’t seem to get rid of them. These weeds are getting to be a problem for us. We’re trying to do a lot of mowing to try to keep them down, but the darn things adapt. They’re growing shorter now and growing a head and flowering close to the ground where the mower doesn’t hit.”

Like many other vegetable growers across the nation, the Monroes have also found opportunity in the longer growing season created by the changing climate. Jacquie estimates that in the last decade they have extended their growing season nearly two months with the help of some physical protection for frosts. They are in the field about a month earlier in the spring and can extend the fall harvest season about a month longer than they used to. “We’re picking things by the first of June and that’s never happened in our lives. That is crazy to think that we are able to produce something and harvest it by the first of June when our official last freeze date is May 15. We’ve extended our harvest season and our income has increased because of it.”

Jacquie and Jerry’s twenty-two-year-old son is weighing the pros and cons of joining his parents in the farm business. He would like to become the fourth generation on the farm, but competition for water in the region makes it difficult to imagine a lifetime in farming. “We are very concerned in the future about our water rights and whether or not we’re going to be able to get our water,” says Jacquie. “The cities are buying the water off the farms and taking it back to the city so people can eat, drink, bathe and water their lawns. Our elderly farmers are selling out. Once a person has gotten to a certain age and there isn’t a family member who wants to take over the farm, they sell their water. I don’t blame them. They finally have something of value that somebody wants and they’re paying them well for it, but it sure hurts the rest of us.”

“I’m to the point where I’m going to start asking at our annual water meeting that the farmers quit selling it, that they rent it to the cities for the rest of their lives and the rest of their children’s lives so that we can keep control of our water. That way the farmers can still have some kind of control over what’s going on out here. The cities are drying up our farms. They say that seven hundred thousand acres is supposed to be dried up in the next ten or fifteen years. It means that water will never go back to those farms. Once it’s gone, it’s gone forever.”

This story is based on a 2014 interview, with a 2022 update.

Full Belly Farm, in the Capay Valley of Northern California, is a 400-acre diversified organic farm raising more than eighty different crops, including vegetables, herbs, nuts, flowers, fruits, grains and livestock. The farm landscape is home to a diverse interweaving of perennial orchards, annual crops and pastures, plus hedgerows and riparian areas managed as habitat for beneficial insects, native pollinators and wildlife. First established by Paul Muller and Dru Rivers in 1984, Full Belly Farm has involved an active partnership since 1989 among four owners who live in three households on or close to the farm: Paul Muller, his wife Dru Rivers, Judith Redmond and Andrew Brait.

Full Belly Farm was designed to be ecologically diverse to foster sustainability on all levels, from healthy soil to content consumers, a stable, fairly compensated workforce, year-round cash flow and an engaging workplace that renews and inspires everyone working on the farm. The productivity of the diversified organic system is based on the use of cover crops and the integration of sheep and poultry to capture and cycle crop nutrients and water, maintain soil health and prevent losses from pests and disease. Virtually all of the production on the farm is irrigated, mostly with water from Cache Creek, which runs along one side of the property.

The farm sells to a diverse mix of direct and wholesale markets in the San Francisco Bay area that includes restaurants, grocers, farmers’ markets and a 1,500-member CSA . Full Belly also supports a number of outreach programs to help create awareness of the importance of farms to all communities.

According to Paul Mueller, three years of extreme drought coupled with dryer and warmer winters, longer and more variable spring and fall seasons and greater weather extremes have created both opportunity and challenge on Full Belly Farm. “The last couple of years we have had the driest January and February on record. That’s the time of year we normally get the moisture that goes deep in the ground, the moisture that serves as the reservoir for our crops that come in the spring. They get their roots down deep and draw on that water. The last couple of years, it just hasn’t been there.”

Declining water supplies have made growing the cover crops so crucial to building soil quality and providing nutrients for crops more challenging. Increased weather variability has made planning and conducting fieldwork more difficult by reducing the periods when work can be done without damaging soils and crops. Paul explains, “Normally we can’t prepare ground for planting in February, but it is so dry now that we can. The challenge is that you’ve got to get your groundwork done as early as possible and when the time is right. We used to get light rains in fall that moistened things up and made large windows to prepare ground, but now variability has narrowed windows and made them less predictable.”

The longer, more variable springs and falls have complicated crop management, but also created opportunities by increasing the length of time the farm can produce valuable spring and fall crops. “The way I look at it is, we are gambling more on the edges. Summer temperatures have been relatively stable, so we can hit our main summer season, but now our main season shifts a couple of weeks forward or backward but those summer crops — melons, tomatoes, beans, peppers — remain the same. If spring weather is unseasonably hot, our spring will end sooner than we thought. If our summer is unseasonably long, then tomatoes will go longer, but the fall crops won’t do quite so well because we did not get them planted early enough. And maybe in mid-winter, the January, February crop mix, if it’s unseasonably warm, we’ll harvest more crops in those months than we normally do. Our crop mix is not changing a lot, but we’re more conscious of how we plan for the edges.” Paul goes on to say that increased weather variability means the edges can have “bigger bounces” and more extreme swings, but that the farmers can push the edges, and sometimes they do really well.

Although water conservation has always been a management focus at Full Belly Farm, heavier rainfall, longer dry periods and continuing drought have encouraged even more thinking about sustainable water management. Paul says that the management team is considering changing up their crop mix to include more drought-tolerant cover crops and is exploring potential cover crops that do better on less water or produce more with the same amount of water than their current cover crops. They are also looking at ways to use cover crop mulches to conserve soil moisture and are weighing the costs and benefits of more water-efficient irrigation systems such as drip and microsprinklers; these involve significant initial investment and add management challenges because they require filtered water, which the farm does not need now.

The managers are also working on landscape-scale improvements in water management. The main water source, Cache Creek, drains a large watershed above the farm. The low fields near the creek are kept in winter cover crops to reduce soil loss in the event of a flood, which would be most likely to occur during heavy winter rains. The farm also actively manages riparian zones along the creek so that when it overflows its banks, flood waters will move over the lower parts of the farm without damaging production areas.

Looking to the future, Paul expressed a number of concerns about the lack of coordinated planning for agricultural adaptation to climate change in his region and elsewhere. He also believes that the recent spike in farmland prices in Northern California is related to climate change. “Investors and growers are moving into more water-secure areas if they can. Other growers are trying to secure water access in other ways. For example, many are investing in deeper wells, even though that reduces water available to other farmers. There is a collision of interests that farmers are starting to pay attention to.”

He suggests that Northern California could reap huge dividends from an investment in a coherent rangeland management strategy designed to improve the health of the regional water cycle.

According to Paul, the new FDA food safety rule conflicts with current water recycling programs and could further restrict water availability in his region. “A lot of the FDA food safety rules are predicated on the assumption of an abundant resource, a stable water supply and a stable climate.” Paul would like to see more programs with NRCS to look at climate threats and develop strategies to create a balance of ecological health and farm protection. “There was a study from Stanford a number of years ago that said that agriculture is being overlooked as a sector that, one, has the largest impact on land use in the country, but two, doesn’t have a coherent strategy as to how they address rising CO2 levels. So maybe under that corn in the Midwest, there could be clover growing, so that as that corn’s done, the clover’s there. And it’s sequestering carbon all fall, and into the spring it starts again. And maybe we invest in other equipment that will allow that to happen, rather than just using herbicides. Let’s take a serious look at polycultural systems and other multilayered systems that provide greater ecological services in terms of sequestering carbon and enhancing climate resilience, and let’s pay farmers for using those practices.”

In the years since this 2014 interview,  Full Belly’s focus on food and farming designed to promote the health of land, people and community has served the farm well through a series of unprecedented disturbances and shocks: continuing drought, wildfires and a global pandemic.   Judith Redmond stepped down from active management of the farm and Paul and Dru’s children, Amon and Jenna Muller, have joined the partnership team.  Paul has continued to explore soil management practices that sequester carbon and enhance climate resilience, most recently as a recipient of a USDA Conservation Innovation Grant to explore no-till management options for the farm. 

In a January 17, 2022 News from the Farm blog post on Full Belly Farm’s website, Paul shares some of the questions ahead in the new growing season. “This week on the farm,” Paul writes, “talk is turning to planning as we begin our annual cycle once again.  We will meet for collective crystal ball gazing and we will go over each crop for a thumbs-up or down, mapping a strategy for this year’s production. Plans are also being mulled over for cover crops, soil improvements, new biological fertility amendments and strategies to enhance our farm’s resilience. This week we try to hone quantities to plant, project market changes that include CSA numbers, and determine the balance between sales to wholesalers, restaurant and local stores and direct to customers.” 

“We must balance that prognostication,” Paul continues, “with the anticipation of crew size. We realize that our 80 or so core workers are all are a year older with changing capacities to be physically able to plant, tend, harvest and pack. There are new labor laws increasing minimum wage and rules changing overtime for farm workers that need to fit into both plans and budgets. These laws are just and past due, but they certainly complicate the budgeting for a farm where labor is near 40 % of our annual expenses. We always add workers returning here in the busier summer months, yet there are fewer farm workers to do the jobs of harvest and stewarding California’s fields, making competition for field workers a critical unknown.”

The farm’s co-owners have collected numerous awards over the years for their success in creating an exemplary model of sustainable agriculture. In 1999, Paul and Dru were named Outstanding Farmers of the Year by the University of California Small Farm Program. Full Belly Farm has been recognized for their leadership in sustainable and organic farming with a 2005 Steward of Sustainable Agriculture or “Sustie” award from the Ecological Farming Association, the 2006 USDA Patrick Madden Award , a Growing Green Award from the NRCD in 2009, and the Leopold Conservation Award in 2014.
