New study into the long-term impacts of regenerative management on vineyard soil health
Interesting new study from Cristina Lazcano’s team at UC Davis, analysing the effect of long-term use of cover cropping, compost, no-till, and grazing across different vineyard conditions. They found that 10+ years of cover cropping is most effective, especially when combined with other practices. Animal integration can jumpstart soil biological activity and carbon cycling. 6+ years of grazing improves soil health even in the absence of long-term cover crops. Stacking practices depends less on the number of practices and more on the combinations as not all combinations are equal. The authors also identified potential benefits from the management of alley rows expanding into the under-vine area.
