A landscaping contractor wants to change the texture of a clay loam soil to meet the specifications for a sandy loam soil. What would they likely add to the clay loam soil? which class of particles in soil is predominately composed of secondary silicate minerals? a gritty feels indicates a high percentage of which soil particle fraction?
the triangle. For example: a soil with 40% sand, 30% silt, and 30% clay will be a clay loam. With a moderate amount of practice, soil textural class can also be reliably determined in the field. If a soil contains 15% or more rock fragments, a rock fragment content modifier is added to the soil’s texture class. For example, the texture class

Primary minerals: present in original rock from which soil is formed. These occur predominantly in sand and silt fractions, and are weathering resistant (quartz, feldspars); Secondary minerals: formed by decomposition of primary minerals, and their subsequent weathering and recomposition into new ones (clay minerals).

Many essential plant nutrients carry positive charges. Example: Potassium (K+) and Zinc (Zn+2) A fertile soil has the capacity to attract and hold these nutrients. Soils with large surface areas, such as clay and O.M., have more CEC and surface area and therefore are generally more fertile. How tightly are they bound to soil in high pH?
