Indicator value
Where annual sorghum is dominant, it indicates fair to poor pasture condition in most pastures. Annual sorghum is usually considered an intermediate species. It is initially an increaser when pastoral condition deteriorates but may decrease under very heavy grazing pressure.
Forage value
Annual sorghum is palatable to livestock when it is young, but becomes unpalatable when it is mature and has very little bulk.
Habitat
Various loamy, sandy and rocky soils.
General description
