The biochar coating of the ball helps protect the seed within from predators such as rodents and insects, dehydration, and extremes of temperature. When wet, the seedball will help retain and prolong a moist environment around the seed to encourage germination.
Seed balls are a form of direct seeding, where the seeds are coated within a ball of clay or other materials such as biochar and then spread by various means. They are mostly used in reforestation, but can also be used to improve pasture, establish mixed improved fallows, wind breaks, wood lots, for biochar or charcoal production, etc. Seed balls or seed bombs are seeds that have been wrapped in soil matter and then dried.
The soil matter is often a mixture of Activated biochar Biochar is a carbon-rich solid that is derived from biomass (organic matter from plants ) that is heated in a limited oxygen environment. … Activated carbon is a carbon-rich solid that is derived from biomass or other carbonaceous substances such as coal or tar pitch, using pyrolysis.) (vermi-compost, Fungiculture along with organic bonding agents to keep the balls uniformed until the seed has a chance to take root
What is a Seed Bomb? It is a technique of planting trees by embedding organic seed balls in the ground. It is also known as aerial reforestation. Vegetation can be introduced in any land by throwing or dropping seed balls in the ground. The best time to execute this process is raining season. Seed Bombs require water for the germination process to activate, which can occur from 14-28 days or can take longer depending on weather conditions, temperatures should reach 20 degrees centigrade for germination.
