Examining data from around the world, researchers have created a global map of soil fertility and explained how it changes between wet and dry climates. The study has been published in the journal Nature. For some time now, scientists have known that climate influences soil chemistry and in particular, soil pH, a measure of acidity or alkalinity.
In dry climates, soil is alkaline; in wet climates, it’s acidic. But what has remained unknown is just how soil pH changes between wet and dry climates. The new research sheds light on that mystery, revealing that the shift occurs abruptly, right at …read more
