cover crop

Thân thiện

A farmer plants a cover crop of clover in the fallow field.

Definition

Noun: A cover crop is a specific type of crop planted primarily not for harvest, but to protect and enrich the soil. Its main purposes are to prevent soil erosion and to provide green manure when plowed under.

Usage

A cover crop is used in agriculture and gardening. It is planted during seasons when the main cash crop is not growing. The term is used as a countable noun.

Examples

• Farmers often plant a cover crop like clover or rye in the fall to protect their fields over the winter.
• Using a cover crop is an effective, sustainable way to improve soil health.
• The garden's fertility increased after the cover crop was tilled into the soil as green manure.

Advanced Usage

• As a soil management strategy: The concept is often discussed in the context of sustainable agriculture, crop rotation, and no-till farming.
  • Integrating cover crops into the rotation cycle helps suppress weeds and retain moisture.

Variants and Related Words

• Green manure: This is a closely related term. A cover crop green manure when it is incorporated into the soil to add nutrients. While all green manure can come from a cover crop, not all cover crops are necessarily used as green manure (some are primarily for erosion control).
• Catch crop: A related but distinct concept. A catch crop is a fast-growing crop planted between main crop plantings to utilize residual nutrients, often for harvest, whereas a cover crop is primarily for soil benefit.

Synonyms

• Soil-improving crop
• Green manure crop (when referring to its use for fertility)

Different Meanings

The term "cover crop" is specific to agriculture and does not have other common meanings. It should not be confused with a crop that is covered (e.g., by a tarp or greenhouse).
