Michelotti, L. A. and Miesel J. R. Source Material and Concentration of Wildfire-Produced Pyrogenic Carbon Influence Post-Fire Soil Nutrient Dynamics. Forests 2015, 6, 1325–1342

The authors wish to make the following corrections to this paper [1]:

We discovered a calculation error in our CO₂ flux data reported in our published manuscript [1]. As a result of the calculation error, the values reported for CO₂-C flux from our laboratory incubation experiment were underestimated by a factor of 3.90. Further, our corrected data indicate that CO₂-C fluxes for type and concentration of wildfire-produced pyrogenic carbon at T₁₀ follow the same trends as the other time points, whereas, due to a graphing error, we had previously ascribed the different T₁₀ response to the initial disturbance of setting up the incubations. Here, we present a corrected figure to replace Figure 3 in the original manuscript. We have compared the results of the statistical analysis of the original dataset to the results of analysis of the corrected dataset, and we found that the conclusions of our study do not differ between the original and the corrected datasets. We present a corrected Table 2 with the correct F and p-values. The corrected Table 2 shows that there are no changes to the conclusions stated in our original manuscript.

The authors apologize for any inconvenience caused to the readers by these changes. We will update the article and the original version will remain available on the article webpage.

Figure 3. Corrected figure: CO₂ flux, in terms of (A) g soil C per day and (B) g soil per day, of soils incubated with charred bark (yellow), charred pine cones (blue), or charred woody debris (green) at zero (black, control), low (0.1%), or high (1.0%) PyC concentrations. The CO₂ concentrations were measured on days 10, 20, 40, and 60 (T₁₀, T₂₀, T₄₀, T₆₀, respectively). The error bars represent one standard error.
