Last week, we reviewed deep drainage on the farm of Con Lehane near Macroom. This week, the method of draining reviewed is different – collector drains about a metre deep and subsoiling to break up a layer of soil that shows very little signs of cracking.

The Kiskeam farm of Sean O’Riordan in north Cork has a mix of free-draining soils that are well developed and maintained (50%) and recently acquired heavy clay soil with poor permeability.
