Wildfires have a significant impact on the properties of the soil. The heat of the fire burns away all of the vegetation and organic matter on the surface of the soil, which makes some nutrients more readily available to the soil while turning others into gases that are lost (chiefly nitrogen). In addition, the heat…
In a radical step away from the tradition of looking at the Earth’s core (center) and mantle (surface portion) separately, scientists have taken a look at the geochemical signatures of each with a new model that considers how the two might interact.
