In Mosier et al. (2021) we assessed differences in soil carbon and nitrogen stocks on five replicate pairs of rangeland farms, with each pair having a farm practicing conventional grazing and the other adaptive multi-paddock grazing. High care was used to identify comparable soil types between the farms in each pair, and the comparability was tested using soil spectral analyses, so that measured differences could be ascribed to management effects. The study objectives did not need pre-treatment baseline measurements since we never claimed to determine stock changes withing a farm over time. Similarly, while the study did not aim, claim, or need to quantify soil carbon stock variability within a farm, it used a fully replicated design at regional scale. Therefore, the criticisms by McGuire regarding lack of pre-treatment baseline data and for the use of pseudoreplication are not pertinent and indicate a lack of understanding of the study design and objective
