    Eric Nelson and his colleagues at Cornell indicate that compost derived from poultry litter was effective in controlling the soil-borne fungal disease Pythium, because it contained high populations of disease suppressive organisms. However, compost derived from municipal biosolids, while as effective in controlling Pythium did so by providing appropriate nourishment to disease suppressive organisms in the soil.

    Does the disease suppression microbes in the poultry compost eat different stuff???

    What does rotting cornmeal do? that is any different than going through the digestive tract of birds??

    Doesn't all food sources have to feed the organisms that thrive on it???

    If beneficials are not thriving, then pathogens have a shot at winning... :)

    I'm not sure what you are asking in the first 3 questions.
    The answer to question 4 is yes.

    I believe that there are millions of different kinds of organisms in any given scoop of dirt, and the ones that find the right conditions and food,,, at the same time,,, are the ones that thrive over the others...

    So if the article has any practical application in the field,,, if the information in the article is useful in the real world of Pythium control,,, will the chicken manure fair better against the pythium than the other biosolids???

    Is it possible that the anti-pythium organisms will die when the poultry litter is applied to the lawn/soil that just happens to be a hostile environment??
