Which chemical property most contributes yo soil formation and what effects do it have?

The chemical property that most contributes to soil formation is mineral composition, particularly the presence of weatherable minerals like feldspar and mica. These minerals break down through weathering processes, releasing essential nutrients such as potassium, calcium, and magnesium into the soil. This nutrient availability influences soil fertility, supporting plant growth and biodiversity. Additionally, the chemical properties of the soil affect its pH and cation exchange capacity, which further impacts nutrient retention and availability to plants.
