2026 Finalists – Teagasc/FBD Environmental Sustainability Awards

Thomas and Peter O’Hanrahan

Co. Kilkenny | Dairy Calf to Beef Farmers

Thomas and Peter are farming 95 ha (including 5ha of forestry), operating a dairy beef system.  They purchase approximately 200 calves annually from local dairy farmers using CBV to select the best genetics.  They finish all cattle on-farm, currently at 23–25 months, with a target of under 24 months. Peter and Thomas have increased the use of protected urea, incorporated red clover into 5.85ha for high-protein silage and reduced chemical N use. A low-emission slurry tanker and GPS fertiliser system improve nutrient efficiency and reduce losses and overlap. Regular soil sampling, lime applications and targeted P and K help to improve soil fertility, while new slurry storage allows nutrients to be applied in suitable conditions.

Biodiversity has been enhanced through 700m of new hedgerow, 20 native trees, rotational hedge cutting and retained mature trees and habitat areas. ACRES includes 4.95ha arable and 3.85ha grassland riparian buffers.

They are DairyBeef500 demo farmers as well as Signpost and ACRES participants. Future plans include further reducing slaughter age, increasing clover, planting trees, rainwater harvesting and installing solar PV.

Maurice Deasy

Co. Tipperary | Tillage Farmer

Maurice has moved from intensive malting barley production to conservation agriculture, with the goal of regenerative farming and agroecology. They use 100% cover crops before spring crops, increased crop rotation to include beans, peas, oilseed rape, oats, wheat and rye, and are reducing cultivation towards no-till. Organic manures, legumes and multi-species swards improve soil health while reducing fertiliser requirements. He has reduced chemical inputs, including insecticides and fungicides, and use GPS technology to improve application efficiency.

Biodiversity has been enhanced through a new pond, additional native and fruit trees, flowering crops, three hives of native Irish black bees, heritage crop production and continued avoidance of insecticides. Water quality is supported through cover crops, improved soil structure and reduced cultivation.

They have diversified through Canvas Brewery, producing single-source beer using farm-grown ingredients and renewable energy from woodland, solar and micro-hydro. A flour mill is also being developed. They participate in ACRES, Farming for Nature, Talamh Beo EIP and other sustainability initiatives, with plans to expand biochar, organic manures, intercropping and no-till.

Co. Cork | Dairy Farmers

This 89 ha, grass-based spring-calving dairy farm milks 140 cows, with a strong focus on maximising pasture utilisation. Over 90% of the farm now incorporates clover, including white and red clover, alongside multispecies swards, reducing reliance on chemical nitrogen. In 2025, 63% of fertiliser N was protected urea, while slurry is applied using LESS/GPS. Annual soil testing and development of a nutrient management plan using NMP Online as well as targeted lime applications and organic manure have improved soil fertility, with 84% of the farm now at optimum pH.

AgNav carbon footprint is 0.81 in 2025, while milk solids was 497kg/cow.

Biodiversity measures include over 2,000 trees planted, 280 m of new hedgerow, riparian buffers, a critical source area, orchard, bird and bat boxes, and reduced chemical sprays. A new 400 m³ slurry tank and managed bunded drain improve water quality. Programme participation includes ACRES, EIP, Trees on the Land and Signpost Advisory. Future plans include more grass, improved genetics, increased clover, reduced nitrogen and ration use.

Matt Hennessy

Co. Tipperary | Organic Tillage Farmer

This farm has undergone a major transition to a fully organic tillage system, converting in 2021 and achieving full organic status in 2023. Organic dairy production ceased in 2024, with 2025 the first full year producing organic winter and spring oats and winter barley.

The system has eliminated chemical fertiliser and pesticides, using red clover, cover crops, multispecies swards, organic manures and straw incorporation to build fertility and soil carbon. Reduced soil disturbance, low ground-pressure machinery and regular soil testing further support soil health. Matt uses the VESS assessment tool to assess soil health on the farm.

Biodiversity has been enhanced through ACRES, a three-year hedgerow cutting and plans for agroforestry. Cover crops, buffer zones and the absence of synthetic inputs help protect water quality. The farm also participates in the Farming for Water Catch Crop EIP and Signpost Advisory Programme.

Future plans include reintroducing organic cattle, establishing 20 acres of agroforestry, expanding multispecies swards and growing intercrops to create a more circular, resilient farming system.

Michael Gleeson

Co. Kerry | Suckler Farmer

Michael has farmed organically for many years, embracing sustainable farming despite the challenging peat and gley nature of his land. He operates a 25-cow Kerry suckler herd, with animals finished from grass and home-grown oats used as feed. No chemical fertiliser is used; slurry and farmyard manure are recycled through careful composting, while rushes are utilised for bedding.

He has planted over 800 metres of hedgerow and, with his family, established 5.6 ha of agroforestry in 2025, including fruit trees to enhance biodiversity.

Buffer zones and closed periods are strictly observed, while improved roadways and careful grazing management help minimise poaching and protect soils. Solar PV was installed in 2025, further increasing farm self-reliance.

Michael participates in ACRES and is actively involved in the Kerry breed. His entrepreneurial background includes organic beef, poultry, milk and barley enterprises.
