This is a fascinating topic. Any comments?

"Free-living plant growth-promoting rhizobacteria (PGPR) can be used in a variety of ways when plant growth enhancements are required. The most intensively researched use of PGPR has been in agriculture and horticulture."

Just like any other microbial infrastructure of our gardens, will the rhizosphere manage with all that we add to the soil? I mean rhizo appears to me as so delicate and perhaps even too much NP or K might cause an imbalance. If we are to seek the optimum for our garden, then perhaps too much as these pumpkins need, may already cause the fragile microorganisms to work poorly. Without knowing all the genes and their characteristics, I believe that just like the article said that plant, it's age, root and even the soil itself can vary the micro community. So IMHO that PGPR would probablty benefit more from an organic garden or as close as we can keep it. I did not see where it would work most effeciently but would have to duplicate this at every aspect of the garden. So fragile, bnut yet so beneficial. If Rhizo is so efecient then we could afford to use less of everything in the garden and it would still have the pumpkins working at their maximum. If this Rhizosphere will make everything work more effeciently then would the less desired bacteria work more effeciently also? Would we need less of everything to grow our pumpkins? Would stretching it too far create a backlash? Sorry, you wanted to know our thoughs and all I came up with is more questions. Did any of it make sense?

What makes sense is the health of the Rhizosphere is directly dependant upon what you put into and do to it. Add mycorrhizal fungi gain a couple of hundred pounds add good organic matter promote bacterial growth, gain another couple of hundred pounds. Add teas and reinoculate gain another couple of hundred pounds.

True and right you are about additional NPK. Why? Our soils high in OM hold all of the nutrients they need. Supplements are not required as they disturb the collective community of good beneficial's held within the confines of the top soil layers.

PGPR is the product of some our teas. A natural tonic and elixir of microbial life. The prevailing information suggests that super charged rhizospheres can and do inhibit the less desirable bacteria. In fact new research is beginning to proclaim that pythium can be entirely controlled using the organic approach. Consider many growers remain in the same patch year after year with similar results and little disease pressure.

PGPR is a product of some of our teas. Which teas are you speaking of? Ii thought PGPR was a product of all teas. Bad Jerry. I will be a first time user of teas this year. Yes I know, bad Jerry. I have read Dirt Doctor and a book called "The Organic Gardener's Handbook Of Natural Insect and Disease Control" and also reading this article that you presented to us is showing me that it is very possible that a supercharged rhizosphere can control more than just pithium. I believe that it can control different types of antagonists in the ground and on the plants, but not all. Whether it is fungal, viral, or bacterial, some can be controlled from each. Hope I explained it well enough.
