kivennäismaalajit

Kivennäismaalajit are soil types primarily composed of mineral particles. These particles are derived from the weathering and erosion of rocks and other geological materials. The size and composition of these mineral particles are key factors in classifying different types of kivennäismaalajit.

The main mineral components are sand, silt, and clay. Sand particles are the largest, ranging from 0.06 to 2 millimeters in diameter, and feel gritty to the touch. Silt particles are smaller, between 0.002 and 0.06 millimeters, and feel smooth or floury. Clay particles are the smallest, less than 0.002 millimeters, and can feel sticky when wet and hard when dry. The relative proportions of these particle sizes determine the texture of the kivennäismaalaji.

Common examples of kivennäismaalajit include sand (hiekka), silt (savi), clay (savi), and loam (multa). Loam is a mixture of sand, silt, and clay, often considered ideal for agriculture due to its balanced properties. The mineral composition also influences the soil's chemical properties, such as its ability to hold nutrients and water. Different mineral compositions can lead to variations in soil fertility and drainage. Understanding these soil types is crucial for various applications, including agriculture, construction, and environmental science.
