1. A New Frontier Below the Horizon: My Work with Pivot Bio Biologicals

Symbiotic Nitrogen (N) fixation is an amazing process that harnesses the power of two organisms (a legume and rhizobium) to mutually benefit one another. However, the process of biological N fixation or the reduction from dinitrogen gas to ammonia/ammonium via the nitrogenase enzyme is an expensive one. The relationship between host plant and rhizobium hinges on the free exchange of N for carbon and other metabolites. Nitrogen fertilizer is often the most limiting nutrient for cereal crop production... T. Roberts
