Soil Erosion and conservation

Front

What is soil erosion?

Back

Soil erosion is the process by which the top layer of soil is removed due to factors like water, wind, and human activities.

Front

What are the main causes of soil erosion?

Back

The main causes of soil erosion include water erosion, wind erosion, overgrazing, deforestation, and poor agricultural practices.

Front

What is topsoil?

Back

Topsoil is the uppermost layer of soil, rich in organic material and nutrients, crucial for plant growth.

Front

How does compaction affect soil?

Back

Compaction reduces soil porosity, making it harder for water and air to penetrate, which can harm plant roots.

Front

What is salinization?

Back

Salinization is the accumulation of salts in the soil, often due to improper irrigation practices, which can hinder plant growth.

Front

What is the impact of overgrazing on soil?

Back

Overgrazing leads to soil erosion as it removes vegetation cover, exposing soil to wind and water.

Front

What are fertilizers?

Back

Fertilizers are substances added to soil to provide essential nutrients that promote plant growth.

Front

What is water erosion?

Back

Water erosion is the removal of soil by water flow, which can occur through rainfall, surface runoff, or river action.

Front

What is wind erosion?

Back

Wind erosion is the process where strong winds blow away loose, dry, and bare soil, often in arid regions.

Front

What is the significance of soil conservation?

Back

Soil conservation involves practices to prevent soil erosion and degradation, ensuring sustainable land use and agricultural productivity.
