The particles that make up soil are categorized into three groups by size: sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Although a soil could be all sand, all clay, or all silt, that's rare. Instead most soils are a combination of the three.
A soil's ability to be influenced by the pH of the water is related to its texture. Soil particles which are smaller, like clays and clay loams, are more influenced than coarse, sandy soils. Fine-textured soils have a higher number of very small particles called colloids.
