What part of the soil is inorganic?

The inorganic part of soil primarily consists of minerals and rock particles, which include sand, silt, and clay. These components originate from the weathering of rocks and contribute to soil's texture and structure. Inorganic materials provide essential nutrients, such as potassium, calcium, and magnesium, which are crucial for plant growth. Overall, the inorganic fraction plays a vital role in soil fertility and ecosystem function.
