Soil Quality--Crop Rotation

When legumes are part of a crop rotation regimen, nitrogen is supplied to the succeeding crop.

• True

• False

Crop yield is often higher when the land is in a rotation regimen than when in monoculture (same crop planted year after year).

• True

• False

A crop that has a high nitrogen demand should be grown before or after legumes are grown?

• Before

• After

To maintain organic matter, you should rotate high residue crops with low residue crops.

• True

• False

By not growing the same crop year after year, which of the following is decreased? Select all that apply

• insects

• diseases

• weeds

• nematodes

Which of the following weakens soil structure, increasing susceptibility to compaction?

• Monoculture

• Crop rotation

An increase in organic matter, improved infiltration, and increased aggregate stability will reduce soil crusting. This results from doing what two things:

• sod-based crop rotation

• monoculture

• leaving crop residues on the soil surface

• tilling up crop residues

There is a (direct or indirect) relationship/correlation to the amount of residue and the population of soil microorganisms?

• DIRECT

• INDIRECT

Crop rotations can help reduce pesticide resistance.

• True

• False

Decaying roots of previously grown crops or grasses provides channels for water infiltration.

• True

• False
