Maaperäluokituksella refers to the classification of soils. This process involves systematically categorizing soils based on their physical, chemical, and biological properties. The primary goal of soil classification is to understand soil behavior, predict its performance for various uses, and facilitate communication among scientists, land managers, and policymakers.

Common classification systems exist worldwide, with the most widely used being the USDA Soil Taxonomy and the World Reference Base for Soil Resources (WRB). These systems utilize a hierarchical structure, starting with broad categories and becoming progressively more specific. Factors considered in classification include soil texture (the proportion of sand, silt, and clay), soil structure (the arrangement of soil particles), soil color, pH, organic matter content, and the presence of diagnostic horizons or layers.

Soil classification is crucial for a wide range of applications. In agriculture, it helps determine the suitability of land for different crops, guides fertilizer management, and informs irrigation strategies. In engineering and construction, it is essential for assessing foundation stability, drainage requirements, and the suitability of soils for building materials. Environmental science utilizes soil classification to understand soil's role in water filtration, nutrient cycling, and carbon sequestration, aiding in land use planning and conservation efforts. Different soil orders or classes represent distinct environments and have unique characteristics that influence their functions and potential uses.
