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.
