    Can you over apply a purely organic fertilizer in regard to nitrogen? In our case Brown Patch in NC. This may have been addressed before, but I haven't been able to find it.

    When you think in terms of the fertilizer 'rotting', in order to become fertilizer then you just need to figure out whether the microbes causing the 'rot' are beneficial or pathogenic...
    They claim that corn meal actually eliminates pathogenic fungi... this may be because the beneficials that are rotting the corn, outcompetes the pathogenic ones...

    It's the same concept of Soybean Meal creating an odor... Well if you pour it on too thick you'll get an odor and I would say that the N is being wasted to volatizing rather than providing too much N for the turf...

    There is no , 'yes or no' answer...

    You've given me the equivalent of a bad song. I'm going to be thinking about this all day not getting it out of my head. Essentially it's a crap shoot?

    It depends on decomposition rates and the C:N of the product being applied. What exactly do you expect to happen from an "over application" of organic products and what products are you applying?

    My concern is applying to much nitrogen during the Spring for tall fescue and increasing the chance of brown patch, which is a big issue in the NC Piedmont region. We have used Nutrite (5-5-4), Milorganite (6-2-0), and another Shemin Nursery provides (I think it's 5-4-3). Bio-solids and or chicken manure. This may be a mute concern, but I just want to be more sure. Part of the application process is to create a better soil structure and I was not sure if putting down more organics in fertilizer form would increase the chances of my concern? I know compost would be the best way to go, but it's much more costly in regard to bettering the soil.

    That Nutrite really requires that you put down lots of P and K, in order to get a normal amount of N... As was noted in another thread, it isn't likely that your grasses require any P, let alone equal amounts to N at every application...
    Milorganite applied at the recommended level should not be too much N and it will release in accordance to moisture availability, so I would imagine that you're no worse off with the brown patch issue than any other fertilizer... working on soil structure and increasing soil fertility goes along way in moderating the need for N, spikes and valleys, that may cause your brown patch problems... sounds like you're on a good track...

    In general less N is required with organic fertilizers and the added organic matter will suppress most turf diseases.
