What is the systematic examination of soils in the field or laboratories known as?

The systematic examination of soils in the field or laboratories is referred to as soil evaluation. This process involves assessing various characteristics of the soil, such as texture, structure, permeability, and nutrient content. Soil evaluation is essential for determining the suitability of the soil for specific applications, especially in the context of setting up a septic system, where understanding the soil’s capacity to absorb and treat wastewater is crucial.

In conducting a soil evaluation, tests may be performed to assess aspects such as the absorption rate of the soil, which can help inform decisions about the design and placement of septic systems. By evaluating soil, professionals can ensure that the right system is implemented to effectively manage wastewater while protecting public health and the environment.

In contrast, other options like soil map, soil absorption rate, and soil injection refer to specific components or methods within the broader context of soil science, rather than the comprehensive assessment process that soil evaluation encapsulates.
