Harvest round up from Tillage Signpost farmers
The harvest of combinable crops is almost complete and for this episode of The Tillage Edge, Michael Hennessy speaks with Tillage Signpost farmers Tom Tierney (Kildare), Don Somers (Wexford) and Tom Barry (Cork) about their 2026 harvests. Don was somewhat disappointed by yields but emphasises that a diverse crop rotation helps reduce risk. Tom Barry reported good yields, which he attributes to high fertility and the use of organic manures. And Tom Tierney teamed up with his neighbour for harvesting — a collaboration he described as very successful this year.

Oilseed rape still the star crop on most farms
Oilseed rape has been a strong performer on Irish farms thanks to consistent yields, high prices and potential for lower production costs. Eoin Lyons, Teagasc advisor, Laois, and Ciarán Collins, Teagasc tillage specialist, join the Tillage Edge podcast to discuss rotational slots, varieties, establishment and early management of oilseed rape. Eoin stresses the importance of avoiding sowing into very dry soils, which can cause uneven emergence and lead to management problems later in the season.

Planting cover crops using a drone
Drone technology is becoming more accessible and increasingly useful on tillage farms and on this episode of The Tillage Edge, Michael Hennessy speaks with Daniel O'Reilly of Aerial Ag Ireland about a large agricultural drone used to apply cover‑crop seed into a standing spring barley crop. Daniel explains how the system works, why it’s well suited to in‑crop application, and how a machine that can carry up to 40 kg of seed can speed up application and reduce the need for ground machinery.

The highs and lows of the harvest so far
With more than half the harvest completed overall (and some areas more than 80% finished), Teagasc advisors, Michael McCarthy (Cork), Mark Trimble (Kilkenny) and John Brophy (Naas) join the podcast to discuss harvest results in their regions. Yields are mixed — most cereal grain has been disappointing, although oilseed rape performed well across the board. As Michael McCarthy noted, “Once again oilseed rape is the star of the show and I have had a number of enquiries about planting it again for next year.” For more episodes and information from the Tillage Edge podcast go to: https://www.teagasc.ie/crops/crops/the-tillage-edge-podcast/ Produced on behalf of Teagasc by LastCastMedia.com

Harvest 2026 – how it is shaping up so far
With the harvest well underway and the continued good weather, farms are proceeding without a hitch. Shay Phelan and Ciaran Collins, Tillage Specialists with Teagasc, join this week's Tillage Edge podcast to discuss harvest yields so far and to consider possible reasons for the results. Both Ciaran and Shay agree winter barley yields are disappointing and pinpoint the factors behind higher yields — and they explain how the absence of those factors has led to lower returns.

Why Cation Exchange Capacity Matters on Your Farm
Eddie Casey spoke to Michael Hennessy at the recent Johnstown Castle Research Centre Open Day to talk about Cation Exchange Capacity (CEC) and why it’s important for farmers to understand their soils and the actions they can take to influence CEC and nutrient retention. Eddie explains what CEC is, how it affects a soil’s ability to hold and supply nutrients, and where soils with higher and lower CEC typically occur across the country.

Brian Caldbeck in the US on Wheat, Drought & the Coming Harvest
Getting an international perspective can help put current grain-market conditions into context — and for this episode of The Tillage Edge, Brian Caldbeck, an Irish grower who runs Rubisco Seeds in Kentucky, USA, joins the show to discuss what he’s seeing across the U.S. crop landscape. Locally in Kentucky wheat yields are good, but recent rains may have created quality concerns, while further west severe drought has significantly reduced production and many fields were used for forage rather than grain production.

Crop update from Kildare
North Kildare farmer, Phillip Harris, and Teagasc advisor, John Brophy, discuss crop progress and management challenges on this week’s Tillage Edge. Phillip describes the adjustments he’s made since changing to strip till establishment, plus a strict containment plan for grass weeds involving crop burn off, fallow and rigorous hand rouging. Phillip recommends herbicide testing for resistance in the identified weeds. John warns that many spring crops face moisture stress and urges caution with herbicide applications, especially tank mixes or spraying marginal crops.

Cost driven choices: Jim McCarthy on his changing machinery policy
We re-join the conversation with Jim McCarthy, who farms an extensive holding in north-eastern Romania, as Jim walks us through recent changes on the farm, most notably his move away from the big-name manufacturers toward more affordable South American machinery to reduce costs. He also discusses the wider crisis facing Romanian agriculture after three severe droughts: bankruptcies among local suppliers, a tightening of credit for farmers, and many crops that have not yet received fertiliser this season.

Crop Update from the South of the Country
Michael McCarthy, a Teagasc tillage advisor, and Tom Barry, a farmer near Mallow, Cork, discuss how crops in their area are progressing. This spring brought three distinct planting windows and Michael is concerned about the later two as emergence is only ok and there is visible damage on the headlands, so those fields will need close monitoring. Tom reports his winter crops are looking well and he’s up to date with fertiliser and spraying operations. He’s used organic slurries for several years and says the improved soil resilience is helping crops cope in a challenging season.

Cover Crops and Cashflow: Jim McCarthy on Farming in Romania
Jim McCarthy, who is farming a large tract of land in Romania, joins this week’s Tillage Edge to talk about the progress on his farm over the past few months. Jim talks about the changes in establishment system and how this is helping maintain yields by trapping more moisture and allowing him to reduce fertiliser inputs. However, Jim remains cautious about the outlook for prices and expresses concern about overall costs rising and eroding profitability of the sector.

Controlling weeds and wild oats in spring cereals
Weed control is becoming more difficult with herbicide resistance of one or more weeds now on most farms. For this episode of The Tillage Edge, Ciaran Collins and Shay Phelan, Tillage Specialists at Teagasc, explain how to get good weed control in spring cereals, even where resistance is an issue. Shay says that sequencing weed control around wild oats can be effective in ensuring good control of all weeds while Ciaran says that tank mixing of a number of products in the same tank is possible, with some care, but he emphasises a strong growing plant is key to minimising damage to the plant.

How important will BYDV control be in 2026?
Dr. Louise McNamara, a researcher with Teagasc, is on this week’s Tillage Edge to talk about the threat posed by aphids and, consequently, BYDV this season. Louise explains that the thresholds, or triggers for action, are similar to previous years, although ongoing research is expected to refine these in the future. She highlights that crops emerging after mid-April are at greatest risk, while noting that location can also play an important role. Aphicide resistance is an important consideration, but pyrethroid insecticides are still providing effective control.
