Fertilizers used in agriculture have significant environmental effects like toxic algal blooms and biodiversity loss. Legumes are a crop with their own method of supplying nitrogen for growth: a symbiotic relationship with rhizobia. Rhizobia can convert atmospheric nitrogen into a form usable by plants, although not all rhizobia fix nitrogen. We hypothesize that by improving rhizobia’s ability to fix nitrogen we can offer an eco-friendly way to improve crop production.
