Plants instead depend upon combined or fixed forms of nitrogen, such as ammonia and nitrate. Currently the majority of this nitrogen is provided to cropping systems in the form of industrially produced nitrogen fertilizers. Use of these fertilizers has led to worldwide ecological problems, such as the formation of coastal dead zones, and requires a high energy input to produce. Biological nitrogen fixation, on the other hand, offers a natural means of providing nitrogen for plants.    Legume aka Pulse Crop) in association with Rhizobium bacteria.   Biological Nitrogen fixation is an important component of organic gardening/farming, forest gardening and other agro-eco practices. Through a partnership with micro-organisms in their roots, some plants can turn atmospheric nitrogen into nitrogen fertilizers useful...
