What is loam?
Loam has a mixture of sand, silt, and clay particles. Typically, loam soils contain approximately 40% by volume sand, 40% by volume silt, and 20% by volume clay. Loam is ideal for most plants and is easy to work.
There are a number of intermediates in the classification of soil texture such as loamy sand or sandy loam but they are still the result of the relative percentages of sand, silt and clay.
