The degradation of plant and animal matter, i.e. the release and the binding of nutrients and trace elements, is one of the most important functions of soil organisms. The pH scale is logarithmic; each unit is 10 times more acid or alkaline than the next. For example, a soil with pH 4.0 is ten times more acid than a soil with pH 5.0, and 100 times more acid than a soil with pH 6.0. A soil’s pH depends on the parent rock (limestone is alkaline, granite is acidic), rainfall, plant materials, and other factors. Soil is often described using several characteristics including texture, structure, density, temperature, color, consistency, and porosity. One of the most important properties of soil is the texture. Texture is a measure of whether the soil is more like sand, silt, or clay. The more like sand a soil is the less water it can hold.
