In the second half of the 20th century, the mass use of fertilizer was part of an agricultural boom called the “green revolution” that was largely credited with averting a global food crisis. Now, the challenge of feeding the world looms again as the population continues to balloon. To help spur the next agricultural revolution, researchers have invented a “bionic” leaf that uses bacteria, sunlight, water and air to make fertilizer in the very soil where crops are grown.
