Decades of excessive phosphorus (P) fertilizer application in intensive agriculture have left significant residues of plant-unavailable soil P, commonly referred to as “legacy-P.” There is an urgent need to utilize legacy-P in agriculture, both because fossil P reserves are dwindling and because P leakage from agricultural systems into the environment already exceeds planetary boundaries. In this opinion paper, we advocate aga...

Tree species differ in their carbon (C) allocation strategies during environmental change. Disentangling species‐specific strategies and contribution to the C balance of mixed forests requires observations at the individual tree level. We measured a complete set of C pools and fluxes at the tree level in five tree species, conifers and broadleaves, co‐existing in a mature evergreen mixed Mediterranean forest. Our study period...
