Examples of soil organic carbon (SOC) concentrations in soil horizons buried below 1 m depth under glacial, erosional, and multiple types of deposits. Letters (a, b) indicate multiple buried soil horizons within a vertical profile. Numbers (1, 2) indicate buried soils from different profiles or sites reported in the same study.

Soil Formation and Parent Materials
Soils form in place over periods of time under the influence of other soil forming factors: climate (heat and moisture), organisms, topography, and parent materials. Parent materials determine the mineral building blocks of most soils, and vary considerably from place to place. They are classified according their mineral characteristics, whether they are bedrock or deposits, and if the latter, the mode of deposition. For further details consult Soil Formation and Parent Material; paying speci...
Soil Profiles and Properties
To study soils we use the soil profile: a vertical cross-section, or side-on view, of about 1 metre depth (Figure 10.1). Soil profiles are normally described at two levels: 1. in the field, different horizons are identified and described using simple observable properties such as colour and texture (feel method) and 2. samples taken from each horizon identified are later subjected to detailed physical and chemical analysis in the laboratory. The soil characteristics that can be assessed in th...
Soil Classification in Canada
The type and combination of horizons present in the soil is used to classify the entire profile into a class of soils such as podzols or gleysols. In Canada, we use the Canadian System of Soil Classification (CSSC). The CSSC identifies 10 major soil orders which are further subdivided. Refer to Chapter 3: Outline of the System and a Key to the Classification of a Pedon for a thorough description. Table 10.2 summarizes the 10 soil orders and associated vegetation communities.

Sep 17, 2024 · The soil profile is one of the most significant components of terrestrial ecosystems, often overlooked yet playing a crucial role in sustaining life on Earth. Soil is not just dirt; it is a dynamic, living system that supports plant life, regulates water, and acts as a medium for microbial processes.
A buried soil profile, or paleosol (above geologist ‘s head), represents soil development during the last interglacial period. A modern soil profile (Alfisol) occurs near the land surface. Source: D. Grimley. Soil is important to our society primarily because it provides the foundation of agriculture and forestry.

Apr 13, 2022 · In agriculture and horticulture, soil generally refers to the medium for plant growth, typically material within the upper meter or two (Figure 9.2.1 9.2. 1). We will use this definition in this chapter. Soil consists predominantly of mineral matter, but also contains organic matter (humus) and living organisms.
