No but I'm very aware of the power of plant exudates in increasing soil life. It's the magic behind regenerative farming with cattle. I'm also a big fan of heavy mulching although I used to bring a lot onto the property. A big difference with Syntropic Ag is growing the mulch on site. 

Healthy, vibrant soil means healthy, vibrant plants. I'm a bit lucky in my climate. Everything explodes with life after the dry season. The trick is keeping things thriving during the dry. Shade & mulch is key.
