If you’ve seen a yogurt commercial or read a wellness blog in the past few years, you may have noticed that probiotics—helpful bacteria—are breaking through to the mainstream.
Probiotics have been advertised as a treatment for everything from allergies to digestive issues to, amazingly, social anxiety. New research indicates that we might not be the only ones to benefit from probiotics, though: a study from the University of Washington suggests that plants might grow bigger and stronger with a dose of bacteria as well.
Friendly bacteria in humans, mostly located in the gastrointestinal system, can have all kinds of effects, breaking down foods and chemicals and turning them into nutrients and compounds that can be more easily or efficiently absorbed by the body. In plants, they work a little bit differently, and are not very well understood.
Past research shows that all plants have what are called endophytes, basically the plant version of probiotics. Endophytes can be bacteria or fungi, and by definition are, at the very least, harmless. (Harmful bacteria or fungi would be classified as some sort of parasite.) But we know hardly anything about how the relationship between the endophyte and the plant itself works.
Older research has focused on endophytes found in little nodules attached to the roots of plants. It’s known that the endophytes in these nodules sometimes serve a similar purpose for plants that probiotics do for us: the endophytes turn a key element for growth, in this case nitrogen, into a form more easily absorbed by the plant. Nobody’s quite sure how they get there (guesses include an early presence in the seed and movement through the environment), and their behavior is mostly a mystery.
The new research takes a huge step forward by finding endophytes elsewhere in the plant body. Working with poplar and willow trees at first, the team, led by Sharon Doty of the University of Washington, found endophytes in leaves, stems and the roots themselves, not just in the nodules attached to the roots.
In a paper published by the American Society of Agronomy, Doty and her team not only isolated these endophytes, but extracted them and transferred them to an entirely different plant species: rice. This is where things get interesting, and possibly groundbreaking, in terms of agriculture, because the rice given a booster shot of endophytes grew fuller and stronger root systems, even though the amount of nitrogen in their greenhouse home soil hadn’t changed.
This is a huge leap forward, because it allows plants to make better use of limited nitrogen in their environment. Nitrogen is the great problem in plant nutrition; nitrogen-based fertilizers can have a really nasty effect on the environment, and by giving the plant a sort of life hack to make the most of the nitrogen it has, we could potentially decrease the amount of nitrogen fertilizer we have to use.
Who knew? Looks like plants aren’t so different from us, after all.

A fast, easy way to compost ALL of your food scraps.
Bokashi is an anaerobic (no air) decomposition process. It is fermentation, think "pickles," "wine," or "yogurt." It is simple to do, provides fast results, puts off little to no smell, and can be convenient for all homes. You can compost all of your food scraps right in your own kitchen, garage, or patio. Bokashi means "Fermented matter" in Japanese and has been practiced by farmers in Japan for centuries. Only recently has Bokashi made it's way to the U.S.

Bokashi VS Bio-digester
While the end result is similar, there are several key differences between the Bokashi method and the Bio-digester method. The main difference is that Bokashi uses beneficial microbes, or living microscopic celluar organisms, while traditional composting uses heat and soil microbes to break down plant matter. The Bokashi method allows you to compost all of your food scraps, and not just the plant based food waste. This results in higher quality compost that has more nutrients and beneficial microbes for your soil.

In this 6th Age of Extinctions, the biosphere’s life-support systems that have allowed humans to ascend are collapsing. Visionary mycological researcher/inventor Paul Stamets illuminates how fungi, particularly mushrooms, offer uniquely powerful, practical solutions we can implement now to boost the biosphere’s immune system and equip us with benign breakthrough mycotechnologies to accelerate the transition to a restored world.
This speech was given at the 2014 Bioneers Annual Conference.
