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 1

Different C and N pools were analyzed in the soil samples collected at two depths (0–15 and 15–30 cm) from the tractor and vine rows of the experimental plots in 2021, three years after practice implementation. Values are means ± standard errors. Letters within the same column indicate significant differences between treatments, locations, and depths at .
