Researchers in Texas tested pigeon peas and found not only all the benefits we typically tout -- nitrogen-fixing, drought-tolerance, shade for other plants and w**d suppression, wind break for other plants -- but a potential for growing where other plants struggle or die.
The idea is that the roots create a chemical process that binds iron -- which already is bound to phosphorous -- and in so doing the phosphorous can be released for the plant to use as a nutrient. This allows pigeon peas to thrive in degraded soils where phosphorous may be unavailable to many crops. Like what other crops? Well things like corn, tomatoes, potatoes, cabbage, broccoli are dependent upon phosphorous being available but do not have the same capabilities of unlocking it.
The more we learn about pigeon peas, the more and more it makes sense of WHY they thrive in conditions where nothing else wants to grow.
(Pictured are new blooms on one of our Follower's pigeon pea trees, revealing the beautiful yellow blooms. She wrote: "The tree has made a beautiful addition to my yard and provides needed shade. Thank you for sharing the seeds. I can't wait to share mine with my neighbors soon."
And....
From the study........
"Pigeon peas are able to exude piscidic acid. Piscidic acid chelates iron, which releases the phosphorus to the plant (Ae et al., 2010). This is very advantageous for pigeon pea because it is able to exclude iron uptake and can grow in soils that would be toxic to other plants."
