Some soil material contains gravel and this is described by modifying the texture class depending on the proportion of gravel present in the sample. For example a silt loam sample with 10 % gravel would be described as - slightly gravelly silt loam.
The texture class can also be modified to include the amount of organic matter in the sample. For example slighty peaty clay loam.
