Earth-friendly perennial grain crops, which grow with less fertilizer, herbicide, fuel, and erosion than grains planted annually, could be available in two decades, according to researchers writing in the current issue of the journal Science.
Perennial grains would be one of the largest innovations in the 10,000 year history of agriculture, and could arrive even sooner with the right breeding programs, said John Reganold, Washington State University (WSU) Regents professor of soil science and lead author of the paper with Jerry Glover, a WSU-trained soil scientist now at the Land Institute in Salina, Kansas.
“It really depends on the breakthroughs,” said Reganold. “The more people involved in this, the more it cuts down the time.”
Published in Science’s influential policy forum, the paper is a call to action as half the world’s growing population lives off marginal land at risk of being degraded by annual grain production. Perennial grains, say the paper’s authors, expand farmers’ ability to sustain the ecological underpinnings of their crops.
“People talk about food security,” said Reganold. “That’s only half the issue. We need to talk about both food and ecosystem security.”
