MATI raises farmer incomes by removing carbon. Today, MATI works in seven countries to spread natural rock dust on the fields of farmers. This raises crop yields, corrects soil acidity, releases nutrients, and delivers durable carbon removal through the process of enhanced rock weathering.
Progress
Across the Global South, 500 million small farms grow a third of the world’s food. Their soil is depleted and the weather is getting harder to farm through. Rock dust raises yields on that soil and removes carbon from the air.

How MATI Helped Urmila Devi protect her crops and cut input costs
My crops used to have pests like stem borer and gundhi bug very frequently, so we had to add lot of pesticides. This added to our costs and reduced the value of the produce. After adding MATI, I have seen a significant reduction in pests and there is 50% less fertilizer needed.
It starts with the farmer. Her yields go up, her soil improves, and she pays nothing in money, labour or time. The carbon removal starts in her field too, and it is measured after it happens, never sold in advance.
