An emerging paradigm su ggests that the dominant form of nutrients can be the driving factor mediat ing plant-microbial-soil interactions and feedbacks\, in addition to the bi ogeochemical cycling of carbon and nutrients. For example\, an inorganic nu trient economy is characteristic of an acquiring system where nutrients cyc le rapidly by microbial “scavengers” whereas an organic nutrient economy is characteristic of a recycling system where nutrient turnover is slower\, p rocessed by the microbial “miners”. Related to this\, I present my three co re research activities addressing several paradigms: Mycorrhizal-Associated Nutrient Economy (MANE) hypothesis\, the microbial mining hypothesis\, and nutrients in synergy hypothesis. This is accomplished by leveraging my 11- year manipulation experiment where the native\, nutrient-poor organic nutri ent economy was shifted towards a nutrient-rich inorganic economy by adding phosphate fertilizer and/or lime in several mixed mesophytic forests. In t his presentation I\, 1) provide evidence that shifting nutrient economics c an have a disproportionate impact on tree growth depending on their symbiot ic associations with fungi. 2) Show increasing soil pH and/or phosphorus ca n suppress late-stage oak litter decay rates and may be contributing to inc reased soil carbon storage. 3) Present novel evidence that increasing phosp horus can also increase the cycling and availability of soil nitrogen\, sho wing these two essential nutrients are tightly linked.
