Assessing the Short-Term Effects of No-Till on Crop Yield, Greenhouse Gas Emissions, and Soil C and N Pools in a Cover-Cropped, Biodynamic Mediterranean Vineyard

Table 3

Cumulative CO2 and N2O emissions by season were measured at the tractor row and soil under the vines in tilled and nontilled plots. Letters within the same row (season) indicate significant differences between tillage treatments at .
