Land used to raise food and fiber crops for human use is

• cropland

• range land

• aquaculture

• pollinators

• reduces pests and weeds

• is more labor intensive

• maximizes efficiency

• simplifies production

A major disadvantage to Monoculture is

• its high use of fertilizers

• simplicity of production

• its need for specialized harvesting

• that it reduces the threat of pests

Over irrigation of shallow rooted plants could cause the water table to rise bringing with it dissolved

• salt

• limestone

• soil

• nutrients

An Earth material that is 45% mineral, 50% pore space and 5% organic matter is called

• soil

• subsoil

• bedrock

• impermeable

Because it has many components which work together, soil can be called a(n)

• system

• degradation

• composite

• litter

Which of these Earth materials is likely the most permeable?

• gravel

• sand

• silt

• clay

The relative abundance of sand, silt and clay in soil can be found by determining its

• texture

• implied ratio

• salinity ratio

• saturation

Good garden soil may

• have equal quantities of sand, silt and clay

• have mostly sand

• have mostly clay

• none of these answers is correct

The most important factor in soil formation is the

• climate

• topography

• rock type

• vegetation type
