    Hello,

    I've been going through process of starting a residential/commercial turf maintenance company( fertilizer, herbicide applications). While looking at sprayer options, I was asked the question of how many gallons per 1000, I would like to spray. I replied with two gallons, and was told that most people spray 4 gallons/1000. I am a golf course superintendent, and have pretty extensive experience in spraying. For the most part, most herbicides and insecticides have a range starting with 1 gallon per 1000. Fungicides usually specify for 2 gallons/1000.

    So I'd like to know what the train of thought of is going with 4. Seems like a lot of waste( extra towing weight, more frequent refills) I am in the Tampa area, maybe its a local thing?

    Thanks for your feedback.

    I think your thinking is correct--one or two gal per thousand is fine--however--if you are planning to mix urea or other liquid fertilizer with the water solution that is different. Urea and potassium chloride have a burn potential (a high salt index). Unless mixed with more water, these two will tend to draw water out of the grass plant. This results in fertilizer burn. Small companies usually have to apply the fertilizer as a second step. This is time consuming--but it results in better quality--if the operator is experienced.

    Ok, at what rate of lbs/1000 of n does it become a problem? I spray fairways with uflexx (46-0-0) all the time at .1-.25 lb of n/ at less than a gallon/10000 with no problems.

    I think 4 gallons is excessive as hell unless you need to get an insecticide down in the soil. My gut feeling is low rates of fertilizer, as you mentioned, in low volume of water is less of a problem on warm season turf than it is for us in cool season. Good luck with your new venture.

    I started at 3/1000 and went to 2/1000 very quickly. Now I'm using a rideon at .25/1000.

    .75 pound of nitrogen as urea, per thousand sq ft in 3 gals of water is acceptable--up to a temperature of 80. Reduce to a half pound of nitrogen and omit potash, if temp is over 80.
    Reduce the rate even more if on fine fescue, or if the soil is dry.
    Sometimes it works to use the pressure adjustment screw; cut the pressure in half to reduce the rate--if the temperature gets hot. Your weed control could be adversely affected of course.
