| Résumé : | Context Conservation Agriculture (CA) aims to enhance the sustainability of agricultural production by minimizing soil disturbance, maintaining soil cover and implementing crop rotations. Despite its potential benefits, the effects of CA on cereal production and soil borne nitrous oxide (N2O) emissions have not yet been investigated at a European scale. Objective We conducted a comprehensive meta-analysis on the effects of CA on cereal yield, yield stability, and N2O emissions compared with conventional agriculture (CONV). Further, we performed a spatial-explicit analysis across different pedoclimatic conditions in Europe to identify regions more susceptible to negative impacts. Methods We compiled a dataset of 58 field experiments (a median duration of 7 years) examining the effect of CA on cereal yields (i.e., winter and spring wheat, barley, oats and maize). Additionally, a separate dataset of 11 field experiments (a median duration of 10 years) was assembled to evaluate CA effects on N2O emissions. A weighted meta-analysis was conducted, and Cochran`s Q test was applied to evaluate heterogeneity in effect sizes associated with pedoclimatic conditions and agronomic management practices. Maps for Europe were created to evaluate the spatial patterns of yield changes under two tillage scenarios - minimum tillage (MT) and no tillage (NT) - both adhering to the core principles of CA. Results Overall, CA led to a statistically significant reduction in cereal yields by 3 % (95 % Confidence Interval (CI): 0.2 %-5 %, n = 58) and a decrease in yield stability by 9 % (95 % CI: 3 %-15 %, n = 50) when compared to CONV. A larger yield gap was linked to a higher topsoil clay content and a decreased tillage depth (p |
