A seed bomb is a little ball generally made up of a combination of compost, clay and seeds. The compost and clay act as a carrier for the seeds so they can be launched over walls or fences and into inaccessible areas such as wasteland or railways.
The compost offers nutrients for the seeds to germinate and grow strong during their infancy and the clay binds the seed bomb, making it hard enough not to break when it hits the ground.
It is used in re-vegetation and reforestation of the fragile ecosystems.
The plantation technique wherein seed balls are sprayed using aerial devices, including planes, helicopters or drones, is known as aerial seeding.
Recently, Udaipur has been chosen for experimenting the seed bombing technique to increase forest cover in Rajasthan.
The Haryana government has employed aerial seeding techniques to improve green cover in the Aravalli area of the State.
