There was a time when "soil" did not exist. During Earth's infancy, hot molten rock covered the planet. As water vapor began to condense and freeze, wind, water and ice weathered the cooling rock, breaking it down into its mineral components. It wasn't until billions of years later that evolving life forms added organic matter to the minerals, creating a substrate in which terrestrial plants and animals could "put down roots". Today, there is a vast array of different types of soils that support a diversity of ecosystems, such as forests, meadows, marshes, bogs and numerous others.
Soil scientists, referred to as pedologists, organize different soils into taxonomic groups, much the same way that biologists and botanists classify animals and plants into families and species, etc., using a taxonomic hierarchy system. There are 12 different soil orders - the highest grouping of soils, worldwide. Akin to a species of organism, soils are broken down into soil series - the lowest grouping. There are 195 named soil series in New Jersey.
You may be pleasantly surprised to learn that New Jersey has a state soil, just as it has a state bird (American Goldfinch), a state flower (Common Blue Violet) and a state tree (Red Oak). Our state soil is called Downer. Read more about Downer soil on OCSCD's blog!
