Researchers are finding that when pulverized rock is applied to agricultural fields, the soil pulls far more carbon from the air and crop yields increase. More studies are underway, but some scientists say this method shows significant benefits for farmers and the climate.
Demineralization occurs rapidly on intensively farmed and tropical soils. Rock dust can reverse this process, rebuilding and restoring life to the soil.
Soil fertility is indeed a widespread global problem. Unless farmers develop creative solutions, people will struggle to grow food in the coming years.

“It’s like that old saying, ‘If mama ain’t happy, nobody’s happy,’ says soil advocate, Holly Arbuckle. “In order to have nutrient dense food, [and healthy people] we need healthy soil.”
Gravel dust could also help with soil nutrient supplementation.

People have been experimenting with gravel dust farming for several years now and with some very positive results.
