Session Title: Seed Endophytes, Rhizophagy, Nutrient Density, Nitrogen Efficiency and Fixation in Corn

This session was recorded during the 11th Organic Seed Growers Conference hosted February 4-11, 2022 by Organic Seed Alliance. More presentations from the conference are available in this playlist.

Over 1,200 seed people from 48 U.S. states and 39 countries from across the Earth participated virtually in the weeklong event. The biennial Organic Seed Growers Conference is the largest conference in the U.S. focused solely on organic seed, and creates spaces where experienced and emerging seed stewards can convene timely conversations, educational trainings, and strategy sessions.

Seed Endophytes, Rhizophagy, Nutrient Density, Nitrogen Efficiency and Fixation in Corn
Breeding corn for 50 seasons for organic/biodynamic conditions by the Mandaamin Institute has led to plants that partner with seed borne endophytes. These endophytes cause rhizophagy, which helps the plants to obtain nutrients from the soil and lead to grain enriched in minerals and essential amino acids. Trials showed that some nitrogen fixing hybrids from the program respond negatively to direct manuring but positively to systems that build soil organic matter. Conventional corn does not appear to have these relationships. However, given the right parentage, environments, and selection, corn can generate such partnerships. Basic research at Rutgers University shows how rhizophagy works, where plants foster endophytes, and the biochemical dialogue associated with supplying plants with nitrogen. The overall results indicate paradigm shifts are needed in how breeders view and work with crops and how farmers fertilize soil and crops.
