Adapting Farm Management to a Changing Climate: Butterworks Farm – part II

“Paying attention to the nuances of the land, I’ve learned to grow really high quality forages, protein, and energy.”  Jack and Anne Lazor, Butterworks Farm, raise their herd of Jersey cows on pasture and high-quality forages in Westfield Vermont and produce a certified organic yoghurt.

For most Vermont farmers, the variable weather of summers from the extreme dry summer of 2016 to the wet cool summer of 2017 has proved challenging.   To meet these challenges, Jack considers increasing the organic matter content of agricultural soils as an important strategy to address many of the impacts of climate change.  The farm has doubled the organic matter content of the soils over the past 40 years. This has significant benefits for water infiltration during times of extreme precipitation, while maintaining soil moisture during dry periods.  The organic matter also improves plant growth, regulates soil temperature fluctuations, and helps resist the erosive forces of rain and flooding.  “It’s all about soil building. I want to see what I can do to increase the OM of the floodplain lands and stay off the tractor when the soil is wet.”

During years of drought, Butterworks Farm has been short on feed for their herd of Jersey cows. They have relied upon increasing their land base to provide more summer forage and more hay in the winter.  Jack noted that maintaining good grazing practices during drought was crucial to the health of the entire agroecosystem.

Specifically, his rule is grazing down to only 3-4 inch height, instead of down to the ground or only 1 inch. He said, “If you want them to regrow quickly, don’t brutalize them.” That requires more land base, which not all farmers have.

Overall, Jack is transitioning is farm land to predominantly perennial forages. “Forage consumption has increased at least 40% for our transition to grassfed, which goes along with transitioning more land out of grain into permanent forage.”

“It’s all about soil building. I want to see what I can do to increase the OM of the floodplain lands and stay off the tractor when the soil is wet.” – Jack Lazor

Business Management Decisions 

Management decisions are informed by weighing a complex set of goals, challenges, constraints and opportunities. Butterworks Farm is transitioning away from grains because there are so many challenges, some of them directly or indirectly climate related. Jack says, “Though I love it, its not financially viable.” The farm is striving the make a transition into the hands of the next generation while reasserting a strong presence in the organic dairy market, though these trends are informed by, but not driven by climate change projections.

Constraints and Challenges

Jack recounted the history of the economic successes and trials of his business over the last 40 years, explaining that when the yogurt business took off and the business was flush with cash, they were able to not only purchase extra equipment and amendments, but also invest in the ecological sustainability and climate resilience of the farm. In this way, Jack linked the farm’s capacity to invest in new adaptive management strategies directly to the financial stability of the farm and market opportunities. Since 2008, the farm has experienced a decline in skim milk yogurt sales, which has dominated much of the farm’s strategic decision-making.

Making the investment into good soil and committing to regenerative agriculture takes a leap of faith, time and money, and Jack sees that some farmers are afraid of that. In Jack’s experience on the land, he sees the return on his investments into the minerals, soil amendments, cover crops and equipment show up in the health of the soil and the plants, and then in the health of his cows and quality of milk and cream.

Greenhouse Gas Mitigation Strategies and Potential

“My main takeaway from being on the land for 40 years is you think you’re being kind to the earth, but there’s always more you can do. Everyone needs to educate themselves and make changes.” – Jack Lazor

Jack emphasized the importance of developing a carbon consciousness. Agriculture has a lot of potential to offset the greenhouse gas emissions in multiple ways. We know that some carbon is captured by perennial, reduced tillage and other systems that increase organic matter, but exactly how much is captured is difficult to measure. Further research is needed on the carbon sequestration potential of grazing systems, and innovative manure and tillage methods. We should be proactive about this, even if the exact amounts of carbon sequestration or reduction in greenhouse gas emissions are unknown- every bit counts!

Butterworks Farm is one of Vermont’s oldest certified organic dairy farms, and has a strong reputation for growing some of the finest organic grains in the state. The farm building complex and surrounding fields are situated on gently sloping fields near the border of Canada. A herd of Jersey cows produces milk which is processed on site into yogurt, kefir and rich Jersey cream for direct and wholesale markets.

Butterworks Farm leases and owns additional parcels in the surrounding area, including some floodplain fields. The farm has grown a diversity of whole and milled grains for regional markets, and animal feed and is currently transitioning to a 100% grassfed operation with a bedded pack system. Alissa White visited Butterworks in early April 2017 to talk to Jack Lazor about how he manages his production with the impacts of climate change in mind.

Climate Vulnerabilities

Regional climate change projections predict agriculture in the northeastern US will experience a variety of direct weather impacts, and indirect impacts as a result of climate change. For Butterworks Farm in northern Vermont, the site-specific vulnerabilities of climate change encompass potentially both direct and indirect climate change impacts.

Direct Climate Change Impacts

  • Warmer temperatures overall,
  • Longer warmer growing seasons,
  • Precipitation increases,
  • Extreme precipitation events,
  • Increased flood damage and erosion,
  • Severe wind and storm hazards,
  • Elevated atmospheric CO2,
  • Increased potential for drought.

Indirect climate change impacts lead to increases in:

  • Weed competition and invasive species,
  • Populations of damaging insects,
  • Incidence of plant pathogens,
  • Livestock heat stress, and
  • Pressure from pathogens and parasites of livestock.

Management goals

Jack and his family balance many goals and challenges when making decisions about managing their farm. Climate concerns fall into both short and long-term decision making at Butterworks, but at the forefront of farm decision making for their family at this time are long-term financial solvency and near-term intergenerational transfer of ownership. Climate change considerations are important, but auxillary to day-to-day management and long-term planning.

How do we manage climate change and weather-related risks at the field scale?

Jack implements a number of practices on the field, specifically, managing for flooding and controlling soil erosion.  He has transitioned land which is particularly prone to flooding from grain production into permanent forage. “We’ve been farming this floodplain property for 20 years…Increased incidence of high water… could come any month of the year now… Then we only loose one cut out of three if there’s high water.” In previous years, the farm has used underseeding cover crops to limit erosion from high intensity rain events.

Jack attributes many benefits to crop rotations, including some that are directly associated with climate risks. His goal is to do less with tillage in all fields because he sees evidence of better soil quality and healthier plants without tillage.  By minimizing tillage and keeping roots in the ground, he maintains soil health with organic matter of 8-9%.

At the field scale, Jack is focused on increasing soil health to buffer the impacts of drought, flooding and extreme precipitation. Cover crops are planted to help hold soil from erosive forces, and land which is particularly flood prone is being transitioned into perennial forages to protect soil.

Building soil biological health and organic matter levels has multiple benefits for the farm.  Jack sees the soil health reflected in the plant growth, and in turn the health of his farm’s Jersey cows.  Increased organic matter limits the damage of extreme precipitation and holds moisture in times of drought.  In response to 2016 summer drought, Jack relied upon increasing his land base for forages and maintaining good rotational grazing practices.  In contrast, grain production has been challenging financially as it’s prone to disease during wet summers and storm events. Overall, the farm’s trajectory is towards perennial forages and away from grain production.

Raised Beds Raise Revenues at Golden Russet Farm

Filed Under: water management by farmclim — Leave a comment
March 24, 2017

Farming for over 30 years in Shoreham, Will and Judy Stevens have noticed climate changes at their organic farm – Golden Russet Farm.  From 1985 to 1995, Will recalls having a number of late frosts in May and that the first frost date typically occurred in early September. However, in the last 20 years, there’ve been only two years where the frost date has been as early as that, with the typical frost date extending to October.

Our growing season is longer and we have more frost-free days; we’ve had years where we’ve had no May frosts and more notably the fall has gotten longer.

In addition to the changes in frost dates, Golden Russet Farm has experienced both extreme storm events, as well as excessively wet growing seasons. 2011 was a persistently wet year, starting in spring and culminating with Tropical Storm Irene in August. Golden Russet Farm was in the red that year with a $34K loss. Much of the crop loss was due to soil saturation, not event flooding per se. The farm’s soils are a layer of loam on top of a layer of clay of varying thickness (2 to14 inches), which inhibits drainage from the root zone. Learning from 2011, Will says,

I’ll take a dry year over a wet year any day. It’s easier to manage dry conditions with irrigation than to be at the mercy of heavy rain events. We’ve noticed over the years that almost every rain event is a violent event. We used to get gentle rain. Now it’s thunderstorms and violent events. With 2.5 inches of rain in an hour, we needed to get rid of the surface water as we didn’t want standing water.

In 2012, working with their existing equipment (a three-bottom moldboard plow), the Stevens built up raised beds by alternating plow passes with 12 inch dead furrows. This roughly formed 36 inch wide ‘beds’. Going to this type of raised bed did add some complications. After soil smoothing and mulching, the Stevens ended up with a final bed width of 30 inches, but this width was too narrow for the transplanter and cultivators as they risked sliding off the beds.

After several years making adjustments, the Stevens invested in a three-point hitch bed shaper in 2015, which can be pulled with their tractor to shape 34-inch beds, moving soil up from the wheel track, so that only two passes need to be made with the press pans. The 34 inch top width of the beds matches up with the cultivator and transplanter. At the same time, drip irrigation tubing is put into place as the beds are made.

Will Stevens with his bed former purchased in 2015

The Stevens started by planting carrots, lettuce, beets, and spinach in some of the raised beds, and brassicas, broccoli and corn in others. In 2016, the Stevens had 12 raised beds of tomatoes, cucumbers, melons, peppers, flowers, and 11 raised beds of garlic across their 1.5 acre field.

With the bed shaper, there’s no need to till the topsoil. In fall 2016, the Stevens bought a chisel plow with four shanks for subsoiling as their soils have a plow pan, which needs to be broken up to make the soils more friable and further improve drainage. For 2017, their plan is to increase by a third the raised bed production area so that they’ll have two acres of raised beds in 2017, and then, they’ll expand to three acres by 2018. With raised beds, Golden Russet flower sales are up 50% from 2015 to 2016.

Raised beds keep me in farming and really reduce the risk of loss, especially mitigating the losses in a bad year. If we’d had raised beds that year (2011), we’d have had fewer crops with wet feet. We lost $4000 worth of carrots, and ended with none that we could sell.”

Soil temperature changes more quickly on raised beds with greater surface area exposed to air.

Raised Bed Equipment

2015 Purchases:

Raised bed shaper              $2,700

Chisel plough -4 shanks  $2,900

Drip tape layer                    $200

These equipment purchases of $5,800 represent only 17% of the cost of the Golden Russet losses in the year of Irene, 2011. Looked at another way, this $5,800 spent in 2015 was easily recouped the next year with the $7,000 annual increase in flower sales. While Golden Russet’s overall use and related costs of irrigation are up, it’s clear that the combination of irrigation to increase yields during dry periods and raised beds to prevent losses during wet periods will result in more stable revenues over the years.

A $5800 investment in equipment for raised beds was easily recouped in one year of increased revenues.

Golden Russet’s plan to move to raised beds arose from the worst case scenario of record wetness and Tropical Storm Irene in 2011, but as Stevens says, “Even in a dry year like 2016, there’s not really a downside.”

When Politics Go Low, Farmers Go High

Filed Under: climate change adaptation, water management by farmclim — Leave a comment
December 19, 2016

While political discourse hit new lows this past year, concern for climate change hit an eight year high in 2016.

US concern for climate change

US concern for climate change

Whatever headwinds affect legislation in the new year, a number of localities, states, and organizations are taking action.

Already, 165+ jurisdictions have signed or endorsed the Under2 MOU. Together, this group including Vermont and our neighboring states, New York, Massachusetts, New Hampshire, 7 other states and five Canadian provinces among others, represents more than 1.08 billion people and $25.7 trillion in GDP, equivalent to more than a third of the global economy.

This global compact among cities, states and provinces aims to limit the increase in global average temperature to below two degrees Celsius.  The Under 2 MOU calls for parties to aim to increase energy efficiency and develop renewable energy and to collaborate on climate change adaption and resilience efforts, scientific assessments, communication and public participation.

It is in this spirit of collaboration, communication, and adaption that UVM Extension Center for Sustainable Agriculture partnered with the USDA Northeast Climate Hub produced three videos showing Northeast farmers talking about their farms and how they’re experiencing climate change and are adapting with cropping strategies, water management and soil protection practices which mitigate climate impacts and help them farm successfully.

 

This past fall, 51.2 percent of the Northeast experienced moderate to exceptional drought, the largest extent since 2002 in the 17-year USDM record. Vermont was 3.5 F degrees warmer than its 20th century average, and this past year was the 2nd warmest year on record. period. This past fall was drier than on average, 2.38 inches less rain that the 20th century average.

In Vermont, Andy Jones, Manager, Intervale Community Farm in Burlington, VT explains how he uses irrigation to maintain soil moisture. Andy talks about his strategies in managing water, whether too much as in the summer of Tropical Storm Irene in 2011 or not enough as in this past summer 2016. Andy shares his thoughts on seeding rates and timing for the cover crops which protect the Intervale’s’s soils and shows the equipment he uses.

In New Hampshire, Pooh Sprague of Edgewater Farm, explains that even though his farm location is within feet of the Connecticut River, in dry periods, there’s no guarantee that he’ll be able to access enough water for this crops.   With increasingly erratic weather in the CT river valley, Poo has increased his use of hoop houses to protect his crops and extend the growing season.

Farms aren’t built in a single person’s lifetime.

Not far from the Connecticut River, Upinngill Farm sits on a hillside overlooking the river valley. The second generation of farmers in the family, Sorrell grew up farming with her father and now has her own two children growing up on the farm.  She says, “farms aren’t built in a single person’s life lifetime.”

Farmers throughout the northeast are experiencing the effects of extreme weather due to climate change and are managing their farms with the resources they can find.    It’s at this community level that the Intervale Community, Edgewater, and Upinngill farms are doing their bit to adapt to the new normal of climate change.

Report on climate change resilience for service providers – Part 1

Filed Under: Uncategorized by farmclim — Leave a comment
July 8, 2015

Rachel Schattman with the Agroecology and Rural Livelihoods Group talks about the Vermont Agricultural Resilience in a Changing Climate Initiative, Rachel Schattman, a former UVM Center for Sustainable Agriculture  and current doctoral candidate, conducted extensive interviews of Vermont farmers and agricultural service providers.  Her goal was to delve into the approaches Vermont farmers are taking to increase resiliency and limit the risks they face due to changing climate.  Rachel’s project also investigates the role of the service provider in improving agricultural resilience and the key adaptation strategies for Northeastern farmers.

The full publication can be found here.

Center for Sustainable Agriculture (CSA):  We find your publication very helpful in terms of identifying and categorizing the dominant adaptation approaches of farmers in the state and region.  Through your interviews, did you get the sense that farmers and service providers were on the same page regarding climate change?  Was it as much of a priority for farmers as it was for service providers?

Rachel:   For this part of the project, we interviewed 15 farmers and 12 service providers. Both groups were clear that climate change is real and that it is a big deal for everyone in agriculture, though not everyone has the same degree of knowledge about climate change or how it will affect agriculture in the northeastern United States. 

People get their information about climate change from different sources, and there are differences in whether people are thinking five years into the future or 50 years into the future.  

 

DSCN0046It’s less a case of farmers thinking one thing and technical service providers thinking another, than a situation where farmers are not all of one mind and nor are technical service providers.

Specifically, we asked farmers how much climate change played into their farm management decisions, and we asked technical service providers if and how they talked about climate change with farmers. The farmers did not all prioritize climate change to the same degree: those that suffered losses with Tropical Storm Irene, or who were located in areas where erosion and flooding are reoccurring challenges, tend to be more concerned. These farmers know that climate change in the Northeast will likely mean more frequent and intense rainstorms, more floods, etc.  We found that these farmers had knowledge of climate change that was more accurate and nuanced than other farmers.  Likewise, some technical service providers were highly knowledgeable about climate change and others were less so, though most had questions about how to best support the farming community through the changes that are to come.

CSA:  Diversification, in a variety of ways, is a time-tested risk mitigation strategy and was a dominant adaptation strategy of the farmers you interviewed.  Was it your impression that farmers diversified initially to mitigate risk from other sources, and then continued after seeing the benefits for climate change resilience?  Or was it the impacts of climate change that prompted the diversification?

Rachel:  Yes, diversification is a widely used strategy for mitigating many different types of risk including economic, ecological and production risks.

These risks are not unique to climate change, but are intensified by the pressures that climate change puts on farms. 

Increased intensification of risk can look like a field that has flooded every 25 years in the past starting to flood more frequently under new climatic conditions. It can also look like spikes in fungal diseases on plants because of more humidity and warmer atmospheric temperatures.

All of the potential ecological changes affect farmers’ financial stability and success.

A farmer’s initial reason for diversifying may have been market related (e.g. wanting to have several different types of sales avenues), crop or product related (e.g. drought or moisture resistant crops, animal and crop systems), or a livelihood decision (e.g. off-farm jobs or other sources of income).  The type of diversification a farmer chooses depends on the specific threats their business faces and the particular resources they have to draw upon.

The farmers that we interviewed reported diversification strategies that were originally adopted for reasons other than climate change.  They also acknowledged that these same strategies put them in a good position as climate change intensifies preexisting threats such as increased frequency and intensity of storms and flooding.

As farmers learn more about climate change, they also tweak their diversification strategies. For example, we interviewed one business owner who chose to site several new greenhouses on a piece of land that is less vulnerable to high winds, which she believes will be a more important factor in the future. This same farmer chose stronger construction materials for the greenhouses because she believes structural integrity of these structures would become more of an issue as intense storms become more frequent.   

Diversification strategies originally adopted for reasons other than climate change put farmers in a good position as climate change intensifies.
