    I'm looking to reduce the tonnage of CGM applied and would like to get some N into my compost tea applications.
    Any ideas?

    Fish is 4% N but according to Tim Wilson it drastically reduces the herd population, probably the phosphoric acid used to stabilize it

    Our liquid corn gluten meal is only 1.5% N and much easier to apply, it also works better because you can control the application and it does not need to be watered in. One 275 gallon tote treats 25.25 acres and only weigh 2000 pounds, this represents 22,000 pounds of bagged CGM

    chilean nitrate is a great source and is plant available as soon as it hits the dirt for a very quick green up, NOFA does not consider it sustainable and does not recommend it though.

    If you want something spreadable you could use alfalfa or soy bean meal, the only problem with them is they attract rodents

    Check my math, that treatment rate is ~.25 gal per 1000 sq ft?

    how does this liquid coincide to recommendations like turf that requires "2 lbs of N / 1000 sq ft"?

    that is correct 1 gallon is mixed with 3 gallons of water, the 4 gallons of mix will treat 4000 sq ft. If the mixture is too viscous or you are already set up for 2 gallons per 1000 mix 1 gallon of Gluten-8 to 6 gallons of water, mix will treat 4000 sq ft
    Gluten-8 is also cheaper than bagged, it does not have to be watered in, does not attract rodents so storage is not an issue, has a 2 year shelf life, is cheaper to ship and is more effective than bagged

    One gallon 9 lb bottle of Gluten-8 is the equivalent to 80 lbs of bagged

    I'd be wary of any recomendation for 2lbs N. Many (20+) years ago we had a lawn that would turn yellow during summer. At the time we were too stupid to check the PH. So we sent a turf sample out and the results came back with a 4lb/1000 N requirement. The soil was so out of wack that the plant could not utilize the nutrients available to it.

    I was not as clear as I should have been, with bagged CGM you are putting out 2 pounds per 1000 of N, with Gluten-8 you are putting out 1/4 to 1/3 of a pound per 1000
