Nitrogen is the macronutrient most essential to plant growth. In today’s agriculture, nitrogen sources are applied to the soil, often multiple times, before planting, at planting and/or side dressed or foliar applied during the season. This can lead to leaching of Nitrates to groundwater in lighter soils, which is an ongoing problem with modern agriculture. In addition, it is estimated that only 30 – 50% of the Nitrogen delivered through chemical fertilization is absorbed by plants. There are certain crops that have a symbiotic relationship with microbes (Plant Growth-Promoting Rhizobacteria- PGPR) that can pull Nitrogen from the Earth’s atmosphere (in a form readily available to plants).
