The calculation of slope in soil assessment is determined by the rise over run, expressed as a percentage. The formula specifically states that the vertical change (rise) is divided by the horizontal distance (run) and then multiplied by 100 to convert it into a percentage. This method is essential in soil judging because slope affects various soil characteristics, including drainage, erosion, and vegetation types.

Using the rise/run formula ensures that you accurately measure how steep the land is, which can affect not only soil conservation practices but also agricultural productivity and land use decisions. Understanding the slope is crucial for assessing potential erosion risks, water runoff patterns, and suitability for certain crops or land uses. This knowledge is particularly important in Iowa, where varied topography can significantly influence soil characteristics and management strategies.
