Soil formation is a complex process that involves the weathering of rocks and minerals, the decomposition of organic matter, and the erosion and deposition of soil particles.

Peat soil is not a major soil type because it is formed from the accumulation of partially decayed plant material in wetlands, rather than from the weathering of rocks and minerals.

Topsoil is the upper layer of soil that is rich in organic matter and is typically darker in color than the subsoil.

Organic matter content is the most important soil property for plant growth because it provides nutrients, improves soil structure, and helps retain moisture.

Wind erosion is the process by which soil is eroded by wind.

Clear-cutting is not a sustainable land use practice because it can lead to soil erosion, loss of biodiversity, and climate change.

Restoration is the process by which soil is restored to its natural state.

Fertilizers are not a type of soil pollution because they are used to improve soil fertility and plant growth.

Compaction is the process by which soil is compacted.

Mining is not a type of land use because it does not involve the use of land for productive purposes.

Salinization is the process by which soil is salinized.

Irrigation is not a type of soil conservation practice because it does not prevent soil erosion.

Alkalization is the process by which soil is alkalized.

Lime is not a type of soil amendment because it is used to adjust soil pH, not to improve soil fertility.

Water erosion is the process by which soil is eroded by water.
