Black Locust & Drought

With its symbiotic bacteria, black locust (Robinia pseudoacacia) makes its own nitrogen fertilizer – and can share it with other tree species. “In early successional temperate forests, symbiotic nitrogen fixation is often the main source of new nitrogen,” says USDA Forest Service scientist Chelcy Miniat. But drought could slow the rate of symbiotic nitrogen fixation,…  More 

Black Locust & Drought Tolerance

By affecting plant growth, drought could potentially affect the nitrogen cycle too. “Some plants – with help from their bacterial companions – can fix atmospheric nitrogen,” says U.S. Forest Service researcher and project leader Chelcy Miniat. Atmospheric nitrogen gas, or N2, is plentiful. This form of nitrogen is inaccessible to most plants. However, legumes such…  More
