Many years ago I attended a talk by Harry Hoitink of THE Ohio State University about using compost in container growing media. It was a little interesting but I had forgotten about Dr. Hoitink until doing some more reading this past weekend. Wow, compost is it!! I'm not sure if he was the only one doing this research but I believe he was the one that established the link between compost on lawns and disease suppression. Have any of you read his stuff?

I always mix in some compost and vermicompost in my potting mix, the flowers especially like it with very long lasting blooms
Although too much can keep the plant to wet and get root rot, I probably add 5 to 10% of the mix as compost
Can you post a link so we can read it too

that didn't work. let me try again to post a link to an article.

Trying again. Aha. I think I've got it.

Very interesting stuff, most forget that bacteria and fungi make enzymes, hormones and motabolites. In the soil they are used to get things that they want like food.
Often they make an enzyme to break down raw materials into food, sometimes they are used to defend themselves against attack
we are trialing a product this year for seed establishment, one set of microbes increases germination, also quickens the germination process, meanwhile another is in the soil making rooting hormones, the root enters the soil from the germinating seed and it is bathed in rooting hormone. It will be released spring 2010
Some of the golf courses using it have stopped using starter fertilizer altogether, don't need it. Big savings
Trichoderma are very effective at killing fungal pathogens. Your article does open up a question, do trichoderma actually kill the fungal pathogen or does it interfere with the pathogens quorum sensing and break down the ability for the pathogen to spread. If you turn off the sensing part in a microbe they believe they are alone and do not multiply until that receptor is filled again. It is literally like a light switch, on and i multiple like mad, off and I basically sit here and eat
We are in trials in California in organic spinach where we are proving this very theory. We are interupting the quorum sensing for powdery mildew, at least that is the theory, so far good to great results

Bacteria quorum sensing. What an amazing world we live in!!!
Department of Molecular Biology, Princeton University, Princeton, New Jersey 08544-1014, USA. cwaters@molbio.princeton.edu
Bacteria communicate with one another using chemical signal molecules. As in higher organisms, the information supplied by these molecules is critical for synchronizing the activities of large groups of cells. In bacteria, chemical communication involves producing, releasing, detecting, and responding to small hormone-like molecules termed autoinducers . This process, termed quorum sensing, allows bacteria to monitor the environment for other bacteria and to alter behavior on a population-wide scale in response to changes in the number and/or species present in a community. Most quorum-sensing-controlled processes are unproductive when undertaken by an individual bacterium acting alone but become beneficial when carried out simultaneously by a large number of cells. Thus, quorum sensing confuses the distinction between prokaryotes and eukaryotes because it enables bacteria to act as multicellular organisms. This review focuses on the architectures of bacterial chemical communication networks; how chemical information is integrated, processed, and transduced to control gene expression; how intra- and interspecies cell-cell communication is accomplished; and the intriguing possibility of prokaryote-eukaryote cross-communication.

Yes, Barry, what an amazing world we live in AND we still have so much to learn about it! I feel like going back to school. Lawnsite....lots to learn here, too.

Hey Dirt if you want to go to school I have some peer review papers that will blow your mind, it gets very technical but gets the point across
email me sometime
