    Odd .... why didn't he "reference" his own paper. :laugh:

    Despite the fact you would have everyone believe you have done an exhaustive review of all science regarding soils, you have not .... not even close. Further, if you think the opinion paper you posted settles the subject of soil health and fertility or lends support to your ridiculous claims here you are sadly mistaken. Beyond that, this paper you have posted primarily addresses sports turf on sand based systems .... how many people here work with sports turf on sand bases? What is the percentage of sand based turf vs. all the rest of the turf in the world? What about parts of the landscape that aren't turf?

    A small sample of published literature I have posted on this subject here before . I am sure you will find some research in there that does not agree with your opinion piece. Links may be broken, or not.

    Come on, Kiril! That majority of your links have nothing to do with turf at all! Apparently you haven't read those that do, since they agree more with my statements than with yours. I suppose next, you'll try to tell me how you practice precision ag on lawns without accounting for differences between lawns!

    Like I've said over and over, you guys can apply whatever you like to your lawns -- I'm not going to stop you. But, you're grasping at straws to find a way to back up what your salesman told you.

    Maybe you should ask yourself one question:

    If building soil microbial populations and soil health was such a good way to manage lawns, why isn't it recommended practice from the majority of university turf programs?

    All right, before this gets out of hand.... instead of slinging mud at each other, I suggest we agree that there are different opinions on how soil biology works and move on. Neither side is going to convince the other and the discussion will continue to disintegrate.

    I brought up the subject of soil health not just as part of a good turf management program but also to highlight other reasons to improve the health of soils.

    Healthy soils
    • Decrease soil erosion and compaction
    • Reduces the amount of nutrients required for healthy plants
    • Conserves water by improving the soil’s ability to retain moisture
    • Stabilizes pH so nutrients can be readily absorbed by plants
    • Allows better root penetration
    • Stimulates root development due to better structure and density of the soil
    • Improves drainage especially in clay soils

    Only one person is slingging mud and ignoring what is written :rolleyes:

    I've come to understand that soils need to have beneficials thriving in them in order for the soils to be providing the environment for the plants to be thriving... that is no longer at issue...
    I always ignore the pages of senseless arguements between 2 reference-slingers, so perhaps I missed the next step of soil management that never gets addressed...

    Every article I've come across, stops short of stating what one can do to increase the beneficial population of microbes... nematodes like to eat bacteria, utilizing the high protien in them, then excrete N that is plant ready... [/b] but what if we are not growing healthy numbers of those bacteria?[/b]

    Come on skip. If you can't draw meaningful parallels between Ag/rangeland/forest soil management to turf & landscapes than you are more ignorant than I had previously thought.

    Again with the ignorance.

    Let's assume I am in the spray and pray biz, what do I apply to my lawns?

    Maybe you should ask yourself why you continue to put words in peoples mouths and make claims you never have any hope of supporting.

    Maybe if you read and understood those references you ignore (you know, the ones you don't post) you might have an answer to your question.

    Maybe some are are but I am not sure about others. I hope everyone reads some of the papers not the post so they can make up their own minds. The Koske paper as I read it is pretty much saying there is a NEED to inoculate new putting greens. The failure was firmly placed on the manufactures of the inoculates, one in being tained, two in dead spores and 3 in not enough spores in the recommended dose for TURF. The companies with viable spored did inoculate and colonize another form of grass called Corn.

    Reading some of these white papers are like pulling teeth but keep in mind, they are subjected to peer review. This is particularly true if someone is trying to get tenure and seek further research funding.

    I do not believe I have read any papers by anyone that says this is a "panacea". It is preferred to salvage and use native top soil, when that is present then you create a good growing medium. These products are an assist.

    Plant size is more of a function of irrigation and fertilization but again the Mycor improves plant uptake but does not replace those items. If you are subject to drought or watering restrictions... again these products are your friend. However, some dealers are less than reputable.
