Soil Infiltration and Erosion Practices

Curtis Swantec from the Indiana County Conservation District explains how water moves through landscapes, focusing on soil infiltration and its impact on water quality. The video covers factors affecting infiltration rates, such as soil compaction and organic layers, and demonstrates how different soil types affect water movement. It highlights the importance of vegetation in preventing pollution and discusses farm practices that protect water quality. The video concludes with practical tips for maintaining water quality in various environments.

What is soil infiltration?

• The compaction of soil by heavy machinery.

• The process of water evaporating from the soil surface.

• The movement of soil particles by wind.

• The absorption of rainwater by the soil surface.

Which factor can decrease the soil infiltration rate?

• Planting a single crop repeatedly.

• Reducing soil compaction.

• Increasing the organic layer.

• Using multiple species cover crops.

What are the three main particles that make up soil?

• Clay, sand, and silt.

• Gravel, sand, and clay.

• Silt, gravel, and loam.

• Loam, clay, and sand.

How does sandy soil affect water drainage?

• It causes water to evaporate quickly.

• It prevents water from infiltrating.

• It has high water capacity and drains well.

• It retains water and drains poorly.

In the demonstration, which soil type showed the fastest water infiltration?

• Silt

• Sand

• Topsoil

• Clay

What is the role of vegetated cover in soil?

• It increases soil compaction.

• It stops pollution by absorbing nutrients.

• It decreases water infiltration.

• It accelerates soil erosion.

What is one farming practice that helps prevent soil erosion?

• Using chemical fertilizers.

• Planting contour strips.

• Increasing soil compaction.

• Removing all vegetation.

How can farmers prevent nutrients from entering streams?

• By increasing soil compaction.

• By planting a single crop.

• By using larger equipment.

• By having setbacks from waterways.

What should you do before fertilizing your lawn?

• Ignore the soil condition.

• Apply as much fertilizer as possible.

• Conduct a soil test.

• Use only chemical fertilizers.

Why is it important to cover bare soil?

• To increase soil compaction.

• To prevent soil erosion.

• To allow water to evaporate.

• To reduce organic matter.
