New paper: 19 years of conservation tillage + cover crops built 50% more soil carbon, but also created macropore networks that triple carbon mineralization rates when soils are wet.

Soil structure changes under reduced tillage and cover cropping enhance carbon mineralization in Mediterranean croplands
Conservation agriculture practices like no-tillage and cover cropping are promoted for rebuilding soil health and sequestering carbon, but their effectiveness in irrigated systems remains questioned....
