    I would be interested in some input on seasonal rates of application of fertilizer. I apply granular fertilizer at maximum rate of 1# per M.

    Can't give you a number like that.

    Grass varieties?
    Soil composites?
    Thatch?
    Sun/shade?
    Irrigated?

    N is only part of the requirements for a healthy turf.

    Most reccommend 2Lbs per year (N per K)
    Cool Season try to lay down about 75% in the Fall (1.5Lbs per K).
    !! Not in one app....1.0 Lbs max,

    Warm season is opposite.....I think. :)

    Detriot Lakes. MN,(cool season) well, let's say you have a K blue lawn. Mostly sun-low to moderate thatch. 4lbs N per year is recommended for best results.

    A shade turf with creeping red fescue should top out at 2lbs N/1000.

    Mixed variety lawns can vary with soil composites. Sandy soils can leach nutrients, so requirements can be higher. Clay soils can hold N-(lots of P)-K, so requirements can be lower.

    I think your question was concerning total nutrients, not just N, so you need to do soil tests to determine P-K levels. Then, you can take into account other factors and apply accordingly.

    Treat every lawn as an individual.

    Good Luck.

    What are your objectives for the site? What is your budget for the site? What are the site characteristics? Have you done a soil test? What are the cultural practices (watering frequency, mulch mowed or not, etc.)? Do you really mean 1# of fert/M or 1# N/M?
