Enhanced nitrogen availability in karst ecosystems by oxalic acid release in the rhizosphere

Enhanced nitrogen availability in karst ecosystems by oxalic acid release in the rhizosphere

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 rel...
