What is not included in the information provided by soil surveys?

Soil surveys primarily focus on assessing and documenting various physical properties of soil, as well as its suitability for different land uses and management practices. Among the key attributes covered in soil surveys are soil texture, soil permeability, and management techniques relevant to soil management and crop production.

Soil texture refers to the relative proportions of different-sized particles in the soil, which can influence water retention, drainage, and nutrient availability. Soil permeability indicates how easily air and water can move through the soil, which is crucial for understanding drainage patterns and potential erosion risks. Management techniques may also be included to provide guidance on how to effectively utilize or improve soil for agricultural or development purposes.

In contrast, while historic land uses might inform current soil conditions or management strategies, they are not a standard element of soil surveys. Historical data typically consist of qualitative assessments rather than quantitative measurements of soil properties and characteristics needed for soil classification. Therefore, historic land uses do not fall under the typical categories of information provided by soil surveys.
