As part of Sustainability Week, dairy farmers John and Brendan Walsh join Emma-Louise Coffey on this week’s episode of The Dairy Edge podcast to discuss the evolution in their farming practices in an effort to improve the sustainability of the farm system. Brendan explains that, while they have always had an environmental focus on the farm, their urgency in the uptake of new practices has escalated in an effort to help combat climate change.                                                                                                                            The Walsh’s have begun to test their slurry and John explains that they have slurry tanks associated with different stock groups: dry cows, weanlings, finishers and an uncovered tank. This gives them more knowledge of the nutrient value of the slurry and the ability to target paddocks deficient in nutrients. Brendan estimates that they have established clover on 62% of the farm. This has allowed them to reduce the quantity of chemical nitrogen spread on the platform. When considering the challenge of bloat, John explains that they lost a cow and had cows blown up last autumn, when there was high growth rate following the drought and an abundance of lush, low fibre grass available. To counteract the risk, the Walsh’s make straw available to cows and estimate they used half a bale per cow last autumn. John urges farmers to strongly consider the adoption of best practice on farms saying, ‘Try everything but don’t be afraid to fail’. For more episodes from the Dairy Edge podcast go to the show page at: https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com.
