We ask you to seek prior approval to use images using the VRO feedback form. } However, the soil needs to be drained first due to its high nutrient and water content. The level of moisture in a soil affected iron compounds that gave color to the subsoil. An even, single colour indicates the soil is well drained. Soil texture is determined by the relative proportion of the three kinds of soil mineral particles, called soil separates: sand, silt, and clay. Varying horizontal bands of colour in the soil often identify a specific soil horizon. Soil texture and soil structure are both unique properties of the soil that will have a profound effect on the behavior of soils, such as water holding capacity, nutrient retention and supply, drainage, and nutrient leaching.. Soil color can indicate the composition of the soil and give clues to the conditions of the soil. return null; " /> Subsoil colors are associated with natural drainage of the soils while the soils were forming.
