For sustainable food production on land, we might soon be looking to the sea

Some ocean microbes capture nutrients from thin air. Researchers demonstrated how these tiny powerhouses could replace synthetic fertilizer on land. Researchers have found that a unique species of marine bacteria is just as effective at fertilizing agricultural soils as mineral fertilizers that are over-applied to croplands worldwide. And, these bacteria could do it with a fraction of the environmental cost that these other conventional fertilizers impose on the land.        Image: Glenn Peters, Unsplash
