What is Soil remineralisation?
To begin with, let’s look at the climate history of the Earth. Everyone’s heard of the Ice Age. But there have been several Ice Ages during the Earth’s history. The remarkable thing about them is they seem to have lasted for roughly the same length of time – around 90,000 years. During this long period, glaciers and walls of ice scrape to and fro over much of the Earth’s surface. Any soil is quickly lost, and the underlying rocks are ground into dust and fine material. This dust, containing a wide range of minerals, is suspended in the ice in huge quantities. At the end of each glacial period, it is deposited over the surface of the Earth as the ice melts and the glaciers retreat. Following the end of each Ice Age, there comes a period, called an interglacial. Plant life returns. Pioneer trees drop leaves and, with the minerals crushed by glaciers, soil forms. Atmospheric carbon is absorbed by expanding tree cover, microbial organisms, and larger animals, increasing organic build up. S
