It all depends on your definition of soil and the context it is used in. What we typically think of as "soil" is top soil/garden soil. This contains organic material: compost, (decayed leaf and plant matter), humus, (concentrated organic material), manure, (animal fecal matter), peat moss, and a small amount of non organic material such as mineral rock, sand, or clay. It is the organic material that will break down and cause some problems under the right circumstances.
People in this forum use garden/potting soil such as Miracle Grow in various ways. "Mineralized soil" is a method created by a hobbyist where they take any type of garden/top/potting soil and enrich it further by adding various things to it.
There are some commercial "potting soils" that are not really what we would call soil at all. They are usually a type of gravel or pellets. These are sold for potted plants, hydroponics, and pond plants. They usually do not contain any organic material that will decay or cloud the water. If what you have has the consistencey of dirt rather than gravel, and its not sand or clay, then it contains organic material.
