Enhanced Nitrogen Availability in Karst Ecosystems by Oxalic Acid Release in the Rhizosphere [PDF]

Frontiers in Plant Science, 2016
In karst ecosystems, a high level of CaCO3 enhances the stabilization of soil organic matter (SOM) and causes nitrogen (N) and/or phosphorus (P) limitation in plants. Oxalic acid has been suggested to be involved in the nutrient-acquisition strategy of plants because its addition can temporarily relieve nutrient limitation. Therefore, understanding how
