Lecture 2a – Soil Texture Soil Texture = %Sand, Silt & Clay in a soil.

Lecture 2a – Soil Texture Soil Texture = %Sand, Silt & Clay in a soil. Soil texture is the single most important physical property of the soil. Knowing the soil texture alone will provide information about: 1) water flow potential, 2) water holding capacity, 3) fertility potential,

Soil Texture

Soil Texture. As we learned, soil is made up of both organic and inorganic components. Soil Texture. Lets focus on just the inorganic mineral solids part of soil. When we investigate the soil mineral part, we see rocks, pebbles and other large rock pieces we call “coarse fragments.”.
