Thus, most phosphorus gets bound up in terrestrial ecosystems because it's less mobile than nitrogen, or gets bound up in aquatic sediments.
WebThe cycles of the key nutrient elements nitrogen (N) and phosphorus (P) have been massively altered by anthropogenic activities. Thus, it is essential to understand how photosynthetic production across diverse ecosystems is, or is not, limited by N and P.
