Regen benefits overestimated, according to Teagasc

Overall, the 23-year tillage system study at Knockbeg showed that the cultivation system had relatively little impact on soil carbon levels. However, min-till systems did increase earthworm and slug populations.

Irish tillage farmers interested in the non-ploughing systems now recommended for "regenerative" agriculture have been advised by Teagasc to “take a flexible approach”.

The advice stems from the results of a 23-year tillage system study in Co Carlow revealed at the recent Teagasc National Tillage Conference.
