Wendy has problems getting flowers to grow in one of her flower beds. If she sends a soil sample to the lab for recommendations to correct her problem, she should take samples from:

• all the flower beds.

• all the flower beds except the problem one.

• the entire lawn.

• the problem flower bed.

Rory is studying the pH scale. What number represents neutral?

• 3

• 5

• 7

• 9

Clayey textured soils are characterized by:

• being loose and single grain.

• having high moisture-holding capacity.

• having large soil particles.

• having low moisture-holding capacity.

The pH test on a soil sample determines the:

• acidity or alkalinity.

• air and water movement.

• amount of nitrogen.

• salinity or salt content.

Compared to other layers of a typical soil profile, the amount of organic matter in the O horizon is:

• about the same.

• less

• more

• none

When indicating or measuring pH, the lower the pH number, the:

• less acid.

• more acidic.

• more alkaline.

• more neutral.

What are the three layers of a typical soil profile starting at the soil surface?

• Bedrock, subsoil, and topsoil

• Subsoil, topsoil, and bedrock

• Topsoil, bedrock, and subsoil

• Topsoil, subsoil, and bedrock

What is the texture of soils that have about equal parts of sand, clay, and silt?

• clayey

• loamy

• sandy

• silty

The most desirable soil for noncontainer outdoor plant production is:

• clay

• loam

• sand

• silt

A soil test report with a pH of 7.2 is:

• extremely acid.

• extremely alkaline.

• mildly acid.

• mildly alkaline.
