Applying biochar to agricultural soils will require extremely fast growth of three subsystems: One to provide adequate material inputs (such as feed crops or agricultural byproducts); one to pyrolyze those inputs into biochar; and a third to distribute the product to farmers who spread it on soils. The growth of each of these subsystems faces unique social, political, and economic opportunities. The authors provide insights on these using three historical analogues: Fertilizer, ethanol fuel, and compost.
