Which soil particle type is the largest in size?

Sand is the largest soil particle type among those listed. Soil particles are categorized by size, with the largest being sand, which has a diameter ranging from 0.05 to 2 millimeters. This larger size allows sand to create air pockets between particles, leading to good drainage and aeration in the soil.

In contrast, clay particles are much smaller, measuring less than 0.002 millimeters in diameter. This small size gives clay a high surface area relative to its volume and causes it to retain moisture very well, but it also means clay can lead to compaction and poor drainage. Silt particles fall in between sand and clay, with sizes ranging from 0.002 to 0.05 millimeters, offering characteristics that allow for moderate water retention and drainage. Organic matter is not classified by particle size like the mineral components of soil; instead, it refers to decomposed plant and animal material, contributing to soil fertility and structure in different ways.

Understanding these distinctions is essential for effective soil management practices and agricultural productivity.
