While the advancement of autonomous farm vehicles offers clear economic and environmental benefits, its future growth also presents the new challenge of ensuring unmanned machines pose no risk to farmers, and the public crossing their land.
During Farm Safety Week (19-23 July 2021) Agri-EPI Centre and the award-winning Hands Free Farm (HFF) project have announced they will hold a hackathon to identify new solutions for robotic farming safety.
As experts in the development of autonomous farm machinery, the HFF team will integrate and evaluate the winning solution at their Midlands plot.
The event is open to any company or individual from any background.
Registration will open on 30 July on the Agri-EPI website.
Agri-EPI’s Business Development Director, Lisa Williams, said: “The benefits of autonomous farm machinery are many but as it becomes more commonplace in the future, and while more and more people recognise the mental health benefits of walking outdoors, it’s essential that farm automation poses no threat to the public.
“We’re excited to have Hands Free Farm on board to help us devise the hackathon and look forward to seeing the participants come up with some really innovative ideas.”
Innovate UK-funded HFF is led by Precision Decisions, with partners Farmscan Ag, Harper Adams University and Agri-EPI Centre. It builds on an earlier project, Hands Free Hectare, in which a hectare of cereal crop was grown without any human entering the hectare of land.
Clive Blacker Clive, Director of lead partner Precision Decisions, said:
“One of the challenges of our project is that, like many typical farms, our 35ha plot includes footpaths and roads with public access. Safety and security of the operation of autonomous machinery is of paramount importance. Addressing this issue will be critical to implementing autonomous machinery and devices in real-world commercial farming settings in the future, and gaining regulatory, market and public acceptance of the technology. We are very excited to be working with Agri-EPI to develop a robotic safety hackathon and cannot wait to see what new thinking and imagination can be applied to agriculture from any background.”

A robotics solution to horticultural labour shortages is being developed to help secure the availability of the UK’s favourite salad veg – the lettuce.
Agri-tech and machinery experts at Grimme, Agri-EPI Centre, Image Development Systems, Harper Adams University and The Centre for Machine Vision at the University of the West of England, Bristol have joined forces with two of the UK’s largest lettuce growers, G’s Fresh and PDM Produce, in the new Innovate UK-funded project to develop a robotic solution to automate lettuce harvesting.
Whole head, or iceberg, lettuce is the UK’s most valuable field vegetable crop. Around 99,000 tonnes were harvested in the UK in 2019i with a market value of £178 million. But access to reliable seasonal labour has been an increasing problem, exacerbated by Brexit and Covid 19 restrictions. Early indications are that a commercial robotic solution could reduce lettuce harvesting labour requirements by around 50%.
Thom Graham, Vegetable Specialist at lead projects partner Grimme said: “One of the greatest challenges facing the horticulture sector is sourcing sufficient seasonal labour to conduct their harvest commitments in a timely manner. In addition, rising cost of labour with no increase in retail price has squeezed margins. Growers are looking at solutions that can reduce labour input costs and maintain their resilience in the sector and we hope our expertise can help.”
Dermot Tobin, Managing Director of Farming at PDM said: “For many decades our business has relied on seasonal labour for harvesting lettuce. Nearly all the lettuce you see on UK supermarket shelves is cut by hand. Sourcing labour is getting really challenging and with wage inflation rising far quicker than return to grower prices margins are really tight. Our industry needs to embrace robotic technology to reduce our reliance on labour so being involved in this project is of the utmost importance to our business.”
Richard Ellis, Innovation & Research Project Manager of G’s subsidiary Salad Harvesting Services Ltd. said: “The process of lettuce harvesting has continuously evolved over the past 30 years, with harvest, packing, date coding, boxing and palletising all completed in the field, within minutes of the crop being cut. The cutting process of an iceberg is the most technically complicated step in the process to automate. We are encouraged to be involved and see the results of this project which offers the potential to reduce reliance on seasonal labour.”
The project will adapt existing leek harvesting machinery to lift the lettuce clear from the ground and grip it in between pinch belts. The lettuce’s outer, or ‘wrapper’, leaves will be mechanically removed to expose the stem. Machine vision will then identify a precise cut point on the stem to separate lettuce head from stem.
A prototype robotic harvester will be developed for field trials in England towards the end of the 2021 UK season, in around September, then at G’s Espana.
Lettuce is also a valuable crop in Europe and the US. 123,000ha of lettuce and chicory was grown in the EU in 2018ii with similar areas in the US. These areas have similar issues of access to seasonal labour, offering a significant potential market for the lettuce robot.

Meeting the challenge of climate change with soil flux analysis
For growers, agri-chemical companies, producers and food retailers monitoring and measuring positive and negative soil flux can help balance greater productivity, sustainability and improved soil health. What is soil flux analysis and what impact does it have on climate change?
Driving net zero reduction
Global Green House Gas emissions are a sensitive topic politically with international agreements of targets and the drive to a net zero status, but there is a debate going on also about who is the most culpable.
Carbon Dioxide (CO2) is by far the highest proportion of GHG emissions at around 75%, but Methane (CH4) and Nitrogen Oxide (N2O), although less in proportion, are respectively 28 times and 310 times more potent than CO2. Most of these emissions come from the burning of fossil fuels for energy production, transportation, manufacturing and building but land use also plays a significant part.
In 1973, the National Soil Inventory (England and Wales) was set to obtain an unbiased estimate of soils, and their carbon content. Since the original survey, further sampling has shown that in most soil types, there has been a progressive decline in carbon content, and the inference is that other temperate regions would show similar traits.
Losses due to land use activity
Inefficient use of fertilisers results in N2O being last as emissions to the atmosphere, and nitrates being leached through the soil into water courses. By targeting applications more effectively to ensure the crop is only given what it can utilise we are able to reduce these losses. Using variable rate applications, or slow release Urea are examples of how land managers are changing behaviour.
Storage and application of slurry and manure also result in emissions. Covered stores, better timing of applications and use of dribble bars and direct injection of slurry rather than splash plates can all contribute.
Rumination results in emissions of CH4 which give cattle and sheep a particularly bad image. This is more a factor in international production than UK, where many animals graze pasture unsuitable for crop production, and that permanent grassland can also be considered a net carbon sink.
Deforestation for agriculture, although not an issue in the UK, but certainly in other parts of the globe for production of soya and palm oil amongst other commodities has a significant impact. We not only lose the of that forest to act as a carbon sink, but the felled and cleared timber both emits CO2 and subjects the cleared areas to the potential of erosion.
Cultivations result in emissions from varied sources, the tractor exhaust (combatted in recent years by addition of EGR and AdBlu technology). The soil surface, as each cultivation releases naturally occurring gases into the lower atmosphere (minimum tillage and direct drilling have had some impact by reducing the amount of soil disturbance)
Natural ecological processes in the soil sub-surface produce and consume gases, and as the soils warm due to climate change, microbial metabolic rates increase resulting in increased CO2 emissions. Gases diffused from the soil surface into the lower atmosphere is known as positive flux, and gases absorbed into the soil is known as negative flux, the balance between the two will determine whether soils are a net source, or a net sink of GHG.
Soil Flux chambers
To calculate this, we need to collect accurate data on soil respiration rates, which can be done by using soil flux chambers. There are several different manufacturers of soil flux chambers, but they can be separated into two main categories.
- Closed chambers where the gases accumulate in the headspace and are sampled by syringe and stored for laboratory processing and analysis.
- PP Systems CPY-5 Canopy Assimilation Chamber (#1)
- Automated chambers which can provide a timely method of sampling, as when coupled with a multiplexer and an analyser, up to 12 chambers can be linked in series and be deployed over a long period to sample and analyse in the field (subject to a reliable power supply)
All of the above equipment is designed to be used in the laboratory or the field (subject to a satisfactory and reliable electricity supply). The Picarro G2201-i (#5) is particularly useful for academic research applications, as it is more robust and user friendly than typical mass spectrometry methods (McCloskey et al 2020).
Strawberry gas flux measurement research
The time saving that can be achieved by automated chamber equipment deployed in a field experiment is demonstrated by Pamona College, California when monitoring soil flux in a commercial strawberry crop. The time in the field and the interpretation was the same using both systems, but the processing of the data represented a huge time saving for the trial, reducing the days from 68 down to 1.

For many farmers and growers, the use of chemical inputs is the largest contribution to their carbon footprint. Aquapulse water technology enables reduced inputs, results in better quality produce naturally, and improves water efficiency. It allows growers to achieve enhanced white root development, more consistent batch colour, and better quality produce whilst using reduced inputs, and less water.
Dr. Hugh Martin, formerly Head of Agricultural Science at the Royal Agricultural University, wrote an independent academic paper on Aquapulse water technology. This article brings forward the highlights of that study.
Aquapulse technology provides naturally clean water lines, promoting healthy bird development, less maintenance & reduced or eliminated chemical use
- Aquapulse is a totally natural technology utilising Feldspar minerals contained in a food grade stainless steel cartridge
- The cartridge can be simply immersed to treat water
- Plants irrigated with Aquapulse treated water show positive physiological growth changes to roots and fruiting
Main benefits for growers
Using Aquapulse can deliver:
- Enhanced crop yield
- Improved quality of produce
- More consistent batch colour
- Crisper fruit & vegetables
- Reduced chemical input
- Reduced water consumption
- Extended post picking shelf
Initial water technology trials
Design of full trials NIAB were commissioned to design and perform scientifically robust and statistically verifiable trials on three crops: dwarf beans, maize and capsicum. The trials were overseen and reported by Dr. Hugh Martin, formerly Head of Agricultural Science at the Royal Agricultural University.
Positive impact plant species
Aquapulse has a physiological and morphological impact on specific plant species (more marked in capsicum and maize, less evident in dwarf beans):
- Increased fruit yield in capsicum
- Increased root mass in capsicum and maize
- Change in the root:shoot balance, with a greater proportion of growth in roots
- There is evidence of advancement in the rate of development of flowering and fruiting.
Water technology treatment follow-up
Additional scientific evaluation is required to further understand the exact mechanism of Aquapulse treated water on plants. This will focus on physiological and morphological impacts on plants and the mechanisms at play. The work will focus on the following objectives:
- Identify specific species that Aquapulse has the greatest impact on
- Identify economic benefits in high-value crops
- Identify opportunities to reduce agricultural inputs (water, crop protection agents, fertilizers)
- Optimise the application of Aquapulse in a farming environment
