Advice for farmers: A new look at the fertiliser value of cattle slurry

Cattle slurry has about 25% less potassium than was previously assumed from research findings in the early 1990s, said Teagasc researchers at the recent Beef 2016 event in Co Meath.

The reduction in K content is not surprising, given the decline in K fertiliser inputs since the 1990s.

But slurry is still a valuable source of nitrogen (N), phosphorus (P) and potassium (K), farmers were told at Beef 2016.
