Thanks to y'all, I have a grasp on how legumes use nodules on their roots to work with soil life to convert atmospheric nitrogen into nitrogen available in the soil that other plants can use.
Read something intriguing, though that leads to my question. What I read, in a description of fieldpeas, stated that harvesting the peas, for eating or planting later, removes much of the nitrogen produced by the plant.
Are they differentiating between the nitrogen fixed in the soil by the roots, and nitrogen carried in the above ground plant?
In other words, where is the greatest benefit in available nitrogen from legumes coming from? The roots, or the above ground biomass? Both?
