Fig. 2: Responses of potential denitrification activity to different management practices.
From: Diverse crop rotations offset yield-scaled nitrogen losses via denitrification
Responses to a phylogenetic diversity of the crops, b proportion of time with crop cover and c presence of ley in the rotation, all during the last 10 years, and d amount of applied nitrogen (N) fertilizer the year of sampling (including both organic and inorganic N), e amount of organic fertilizers during the last 4 years, and f number of tillage occurrences the year of sampling. The blue line represents the estimated effect of each variable conditional upon the other terms in the model. The grey dots denote the partial residuals, and the shaded area indicates 95% confidence intervals. P-values are indicated on the corresponding plots. See Supplementary Table 2 for summary of the model statistics.
