Sunflower is a warm season broadleaf that is used as a cover crop - either as a "break crop" in certain crop rotations; or to add diversity to mixtures.

​

Sunflower has certain benefits as a "green manure":

• Produces high levels of organic matter.

• On termination of the crop, a dense moisture-conserving mat is formed. 

• Forms a deep, extensive root system that hosts mycorrhizal fungi. 

• The broad leaves and quick establishment assists in smothering weeds.

• Attracts pollinators.

• Used as part of "insect havens" - attracting insect predators.
