It involves pulverising silicate rocks such as basalt – left over from ancient volcanic eruptions – to bypass the slow weathering action. The resulting powder, with a high reactive surface area, is then spread on large areas of agricultural land where plant roots and microbes in the soil speed up the chemical reactions.
