Eucalypts is a group of species with great economic importance. However their development can be limited due to the low phosphorus (P) availability in tropical soils. Contrarily, manganese (Mn) is a highly available micronutrient in such soil types, and can cause phytotoxicity when in excess. Eucalypt species capable of mobilizing P in soils via exudation of organic acids into the rhizosp…
