The Yorkshire farming household behind the profitable Wold High Brewery and Yorkshire’s first single-malt whisky distillery is utilizing the newest precision mapping expertise in its drive in the direction of a low-carbon, sustainable future.
Carbon and soil well being are a serious focus at Hunmanby Grange and third-generation farmer Tom Mellor has lengthy recognised the significance of those given his ardour for sustainability and regenerative agriculture ideas.

Hunmanby Grange Farm
- 240ha household farm
- Shallow lime-rich soils over chalk
- Cropping consists of spring barley, winter barley, winter wheat, land rented for potatoes, and overwinter cowl crops
- Sturdy environmental focus, with stewardship margins and wildlife-rich grassland (AB15 two-year ley)
- Most arable work carried out by native contractor, other than drilling in autumn and spring
- Diversified into brewing in 2003, when Wold High Brewery was based, and in 2012 when the Spirit of Yorkshire Distillery was established
- Sturdy concentrate on sustainability and regenerative farming ideas
Cultivation carbon prices
Overwinter cowl crops have been a part of the rotation for greater than 5 years, and Tom is working with Future Meals Options to guage their worth for carbon sequestration.
In 2018, the farm moved to direct-drilling most crops, though he recognises the necessity to stay versatile and adapt to conditions as they come up.
For instance, focused shallow ploughing is being thought of as a cultural management for grassweeds, notably brome, which has turn into extra problematic on some fields.
Tom additionally appreciates the worth of utilizing exterior experience the place needed, and two years in the past, began working with native Hutchinsons agronomist Ben Jagger, and farm enterprise advisor Will Foyle, to assist plan the farm’s strategic route, in addition to help with day-to-day agronomy.
This began with evaluation of 2022 discipline efficiency and manufacturing prices utilizing Omnia Enterprise Supervisor.
Yield maps have been uploaded to the system, and mixed with agronomic information from Muddy Boots, monetary costings, and different info from the farm’s contractor, together with discipline operations, equipment varieties, gasoline consumption and work charges.
This allowed them to incorporate each the carbon value when it comes to gasoline use, but additionally the embedded carbon (that related to the manufacture of the equipment) when benchmarking efficiency.
Utilizing this info, the Omnia system mapped variations in variable and direct prices throughout particular person fields in £/ha, and confirmed the related carbon “value” (carbon dioxide equivalents (CO2e)/ha).
One significantly fascinating perception was the comparability between two fields of Gleam winter wheat; one direct-drilled in 2021-22, the opposite ploughed, pressed and drilled.
The direct-drilled discipline averaged 9.56 t/ha, and had a complete operation value of £270/ha, or 1.57t/ha CO2e, equating to 0.16t of carbon dioxide/t.
In distinction, the ploughed discipline value extra to determine at £400/ha, nevertheless the upper common yield of 10.91t/ha diluted the carbon value to 1.61t/ha CO2e or 0.15t of carbon dioxide/t.
“This one instance reveals how you will need to have in mind the influence of yield dilution when assessing prices and carbon.
“However, equally, manufacturing techniques should be financially, agronomically and environmentally sustainable, so we will’t contemplate something in isolation,” Ben says.
Full Terramap evaluation of the entire farm over the previous two seasons offers an additional layer of knowledge, together with detailed mapping of all main soil properties, equivalent to nutrient ranges, pH, soil texture, natural matter, and carbon, with outcomes uploaded to Omnia.
Apparently, this reveals that within the two fields with contrasting institution techniques, natural and energetic carbon ranges have been each decrease within the ploughed discipline in contrast with the direct-drilled space, probably because of the oxidation of natural matter throughout the inverted soil.
It once more highlights the complexity of resolution making, as whereas ploughing might not be the most effective answer when it comes to soil carbon or institution prices, the rise in brome populations in some direct-drilled fields may have a extra damaging long-term impact if left unchecked, by means of lowered yields and the necessity for management.
The group insists it’s nonetheless early days when it comes to figuring out the optimum stability when it comes to what’s finest financially, agronomically and environmentally, however understands that precisely measuring the variables concerned and benchmarking efficiency is vital to creating extra knowledgeable choices.
It’s hoped that having the ability to quantify the carbon footprint of barley going into the brewery may even assist them obtain their ambition to supply “carbon-neutral beer” someday within the close to future.
“It might be a extremely good distinctive promoting level if we may sooner or later say that each one the barley going into our beer is carbon impartial, in addition to being produced from our personal farm,” says Kate.
“In the mean time, we’re most likely about three-quarters of the best way there, however zero carbon is one thing we’d like to realize.”
Synthetic fertiliser is the largest contributor to the carbon footprint of many arable crops, and Ben says that is an space the place there could also be scope to enhance.
“Reaching excessive nutrient use effectivity is a problem on the shallow, chalky soils, so we’re making an attempt to evaluate the place there are alternatives to scale back inputs with out jeopardising grain high quality or yield.”
For nitrogen, wheats sometimes obtain 180-200kg/ha of N, winter barley will get 150 kg/ha of N and spring barley nearer 130 kg/ha of N.
Prior to now two seasons, which have been each very dry, Omnia evaluation has helped them trim complete utilized nitrogen on winter and spring barley by 10kg/ha, with no discount in yield or high quality, he notes.
“It’s a begin. We’re nonetheless seeking to discover the place the equilibrium is for this farm, however on a regular basis should be conscious that what we do within the discipline has implications for different components of the enterprise when it comes to grain high quality and brewing potential.”
Utilizing the soil mapping evaluation to raised perceive the interactions between soil properties, nutrient availability, and the influence of canopy crops may even assist with such decision-making, says Kate, and should open up alternatives for financial savings sooner or later.
Brewing and distilling success at Wold High brewery
Ever for the reason that Mellor household moved to Hunmanby Grange Farm in 1945, successive generations have all the time recognised the significance of driving the enterprise ahead.
Third-generation farmer Tom Mellor isn’t any exception, and believes the necessity to adapt has by no means been better given agriculture’s present tempo of change, unstable markets, and binding authorities targets to scale back carbon, that are steadily filtering by means of to producers.
“Farming is transferring at a tempo I’ve not seen in my lifetime, and I’m certain we’ll face many new challenges within the subsequent 10-15 years, so it’s important we plan for this and hold transferring ahead.”
It’s 20 years since Wold High Brewery was established by Tom and his spouse Gill, initially to diversify earnings throughout a tricky interval for farming, including worth to spring barley grown on the 240ha farm.
The brewery, now managed by Tom’s daughter, Kate Balchin, has grown right into a massively profitable enterprise in its personal proper, producing a spread of award-wining cask, keg and bottled beers offered nationwide.
In 2012, Tom and enterprise companion David Thompson additionally established the Spirit of Yorkshire Distillery, of which his different daughter, Jenni Ashwood, is now the advertising and marketing director.
There stays a robust pure synergy between the companies, with sustainability and provenance at its core.
The brewery nonetheless proudly makes use of practically all home-grown barley, about 500t yearly, with the primary selection being Laureate, plus some Vessel, the one non-GN winter malting barley on the UK market.
Barley is purchased by the brewery from the farm on the going market value, offered to an area maltster, Muntons, then that ring-fenced batch of malted barley is purchased again for brewing.
“It’s not simply that we’re utilizing home-grown barley in our brewing and distilling, however we even have full management over how it’s grown,” Tom says.
Whereas the diversification has been very profitable, he’s eager to make sure the farm stays financially and environmentally sustainable, unbiased from the opposite enterprises.
“The farm is the guts of our enterprise, so it’s actually essential it’s worthwhile and never only a car for allied components of the enterprise.”
