definition of loam types
Loam is a type of soil, consisting of sand, silt, and clay. It occurs in various compositions under the upper humus layer in all parts of the world. Depending on their grain size and their formation, there exist different types of loam: alluvial loam, boulder loam, loess loam, and mountain loam.
Alluvial loam, also known as high tide loam, is characterized by its fluvial-morphological formation process. So, flowing water constantly transformed the muddy loose rock. Subsequently, the fine sediments subsided and alluvial loam arose. It is a yellowish, very clayey loam consisting of very small grains which have been rounded by the water.
This whole process did not happen overnight. Loam is the result of thousands of years of development.
