What is the correct order of soil particle sizes from smallest to largest?

The correct order of soil particle sizes from smallest to largest is indeed Clay, Silt, and then Sand. Clay particles are the smallest, measuring less than 0.002 millimeters in diameter. They are known for their ability to hold water and nutrients due to their large surface area relative to their volume.

Next in size are silt particles, which range from 0.002 to 0.05 millimeters. Silt has a smooth texture and retains moisture better than sand, but does not compact as much as clay.

Finally, sand particles are the largest of the three, ranging from 0.05 to 2 millimeters. Sand particles are coarse and do not retain water as well as clay or silt, allowing for good drainage.

Understanding the different sizes is essential for soil management and informs how soil behaves in terms of water retention, aeration, and nutrient supply, which are crucial factors in agriculture, gardening, and environmental conservation practices.
