Fig. 1: Particulate C:P and N:P are sensitive to the nutrient N:P supply ratio, while C:N is more constant.

Concentrations of particulate carbon (C) (a), nitrogen (N) (b), and phosphorus (P) (c) in the incubations over time show that particulate C accumulation was stimulated by the addition of N and was equivalent whether or not P was added along with N. Error bars represent 1 σ for treatment replicates (n = 6, except for all -N+P, +N+P on day 11 in a–c, and -N-P on day 29 in c where n = 5). Also shown are relationships between particulate C and N (d), C and P (e), and N and P (f). Point shapes indicate sampling day. Sub-treatments are denoted in d-f by the point fill color; added iron (+Fe) treatments are filled black and no iron added (‒Fe) treatments are filled white. Source data are provided as a Source Data file.
