The three main types of soil particles are sand, silt, and clay. These soil particles are categorized based on their size, which significantly affects soil properties and behavior.

Sand particles are the largest among the three, typically ranging from 0.05 mm to 2.0 mm in diameter. This larger size allows sand to provide excellent drainage and aeration, making it suitable for many types of crops that require well-drained soil.

Silt is intermediate in size, with particles ranging from 0.002 mm to 0.05 mm. Silt holds more moisture than sand and contributes to the soil's fertility and nutrient-holding capacity. It has a smooth texture and can enhance the overall texture of soil when mixed with sand and clay.

Clay particles are the smallest, measuring less than 0.002 mm in diameter. Clay has a high surface area relative to its volume, allowing it to hold moisture and nutrients effectively. However, its small size can lead to compactness, which may restrict water movement and root growth if not managed properly.

Understanding these three particle types is essential for soil management, as their proportions influence everything from drainage and aeration to nutrient retention and soil structure. Options that include loam, gravel, or organic
