Grazing Management and Soil Health on the Walsh Farm

John and Brendan Walsh & family were the 2021 Clover & Sustainability winners in the Grassland Farmer of the Year Competition. They farm in Ballylooby, Co. Tipperary.

The Walsh family, along with the Teagasc Grass10 team and local Teagasc Advisors, hosted a farm walk on Tuesday, 4th October to share some of their experience and knowledge when it comes to farming sustainably.

Brendan Walsh has been measuring grass since 2014 on his farm, with 54 walks per year recorded over the past five years, and sees great benefit in measuring grass. He measures the grass every five days during the summer. The main advantage is that it allows Brendan to plan ahead and decide which paddocks to graze in a very well informed way. It also helps to identify poorer performing paddocks and this means those can be targeted for reseeding. The pre grazing yield on the farm is 1,518 kgDM/ha and average grown is 12,926 kgDM/ha.

Soil health is a very important factor in the success of the farm. The Walsh’s sample their soil every year in order to get as much information as possible so that they can make decisions each year to keep the soil in good health. The soil fertility on the farm is excellent with soil above a pH of 6.2, 85% of the farm at or above index 3 for P, and 75% of the farm at or above index 3 for K. This reduces the farms reliance on chemical fertiliser, the Walsh’s have spread 130 kg of nitrogen so far this year and have grown 11 tonnes.
