Barren Fields Inoculated with Healthy Soil Can Heal
Cornucopia’s Take: Small amounts of healthy soil can help revive barren land. What processes cause the increase in nematodes, bacteria, and fungi remain unclear. The study reaffirms the importance of soil in organic production.
Soil ‘booster shots’ could turn barren lands green

Want to make your barren yard lush again? Just add a bit of soil from your local meadow. A new study reveals that the addition of foreign soil—and more importantly, the organisms it contains—can shape which plants will grow in the future. Such “inoculations” could even help bring back fallow farmlands and turn deserts green.
“This is a really cool and remarkable study,” says Harsh Bais, a root biologist at the University of Delaware, Newark, who was not involved in the work. “Dirt matters.”
Soil isn’t as simple as it seems. It contains microscopic bacteria and fungi, as well as tiny worms called nematodes and other invertebrates. Ecologists have long known that these underground communities build critical partnerships with the plants growing nearby. But many of these partnerships remain a mystery. Small-scale studies in greenhouses have shown that adding the right soil can promote the growth of a particular plant community, and some researchers have even tried soil transplantation—replacing one soil with another—to get certain endangered plants to grow.
