When documenting the specific benefit of a management practice, the potential magnitude of this change will depend on both inherent and dynamic soil properties (Fig. 3.3). For example, when considering tillage, visualizing a disturbance continuum can be helpful because humans have the ability to shape soils from a range tools and techniques, including tillage (Reicosky, 2015) and drainage (Dinnes et al., 2002; Skaggs et al., 1994). Similarly, when comparing a range of management practices, selection of two practices with major differences (e.g., moldboard plow vs native prairie grass) will likely show more significant differences due to contrasting levels of soil disruption, plant species, and external inputs (Veum et al., 2014; Veum et al., 2015). Furthermore, the way in which the comparisons are statistically conducted can definitely influence “how much” of an effect was present and detectable (van Es and Karlen, 2019; Roper et al., 2017).
