The soil had a wealth of minerals, trace elements, and rich humus. Some of these deposits are exceedingly rich in a little known substance called fulvic acid.

The downward movement of minerals through soil layers is known as leaching. This process occurs when water percolates through the soil, carrying minerals with it to lower layers. Leaching can impact soil fertility and nutrient availability for plants.
Leaching is the process in which water seeping downward through the soil dissolves and carries minerals from the upper horizons into lower horizons. This movement of minerals can impact the soil fertility and nutrient availability in different layers of the soil profile.
Truly good soil is made up of the following: A proper balance of clay, sand and silt, with a goodly addition of humus (decomposed organic matter). If it has those things, it will automatically have the minerals and tiny microorganisms. Such soil is called "rich loam", and is an ideal growing medium for most things.
The zone of leaching is found in the E horizon of soil. This horizon is characterized by the removal of minerals, organic matter, and other solutes due to the downward movement of water through the soil profile.
Top soil usually has humus and minerals which are often absent from sand, clay or gravel.
The mixture of soil is called humus, which is a combination of decayed organic matter, minerals, and other substances in the soil that provide nutrients for plants to grow.
