6.E.2.4 - Soil Stewardship Test Review

A farmer plows a field but leaves it unplanted for several years. How will this most likely affect the soil in the field?

• The soil will erode.

• The soil pH will change.

• The soil horizon will change.

• The size of the soil particles will decrease.

Which action would be most effective in improving the future soil quality of large-scale agricultural industries?

• eliminating crop rotation

• planting high-yielding crops

• using genetically modified seeds

• bordering all fields with fast-growing trees

How can a farmer monitor the soil quality on his farm?

• by increasing the use of water

• by testing the nutrient content

• by decreasing vegetable growth

• by installing a fence around the fields

How is remote sensing used to monitor soil quality?

• It tests nutrient levels in the soil.

• It samples for pollutants in the soil.

• It helps locate areas of high soil erosion.

• It ensures plant roots attach to soil particles.

Why is it important to test soil acidity?

• to know which crops to plant

• to ensure the soil is healthy for plants

• to check whether fertilizer can be used

• to determine the amount of soil erosion

How does plowing a field perpendicular to the slope of a hill help maintain good soil quality?

• It prevents water runoff.

• It adds nutrients into the soil.

• It allows water to fill underground reserves.

• It prevents pests from burrowing in the soil.

A farmer uses remote sensing as part of his farm management. What is the most likely goal of this practice?

• to improve soil quality and prevent erosion

• to reduce soil cover in the fields

• to increase pollination of crops

• to decrease crop yield

How can a farmer use the shape of the land to prevent soil loss and to conserve water?

• by constantly plowing the fields

• by plowing fields along their contours

• by rotating the crops grown in the fields

• by removing crops from the fields during heavy rain

Why would a gardener want earthworms in a garden?

• Earthworms break down organic materials into nutrients that plants use to grow.

• Earthworms travel long distances and help move plant seeds to new areas.

• Earthworms protect plants from predators by releasing poison into the soil.

• Earthworms eat the leaves of plants but give the plants water in return.

What provides the organic matter needed for the most fertile soil?

• eroded sand

• moving water

• decaying plants

• weathered bedrock
