Spraying iron sulphate

Hi, 
Currently treating my lawn after years of neglect and starting to rid of the moss. 
It's approx 196m2. 
I have a 20L sprayer and the iron sulphate I have says to use 3g/L/m2 therefore I'm going to need the best part of 10 spray loads.

I've done one pass already and it's taken almost 45mins to do 20m2. Is it possible to ramp up the iron dosage so I dont have to do as many spray loads and then water in with sprinklers?

The reason I ask is it's going to take many hours and it kills my back after a while plus the instructions say you can actually apply the granuals direct but I dubious about getting an even coverage thag way so would prefer the spray on method.

    It's a big risk.

    Why not use a watering can with a rose? 
    It may need filling more often, but it only takes about a minute to empty

    Just remember to dissolve the granules in warm water as they will clog up your rose or sprayer. I use 4 canes with string 1 metre apart and use watering can and get good results using this method.

    @jonny_supersonics for 196 m2 of lawn you need 588g of product.  196m2 with 3g of product.  196 x 3 = 588.

    Yeah I got that bit cheers, I was just looking for a more effective way of applying that as its in 196L of water and takes ages to do 20m2 in my knapsack sprayer so going to try a 10L rose head watering can, not sure why I never thought of that initially

    I use a watering can with a fine rose.  W/c is best as no risk of over-spraying.  6 tablespoons of FeSO4 in a 1.5 gallon watering can.  To a fine lawn I apply at the rate of 3 watering cans to 100m2.  I use the topping up of the w/c to mix the FeSo4, it dissolves quite quickly in cold water.    It's all done in 1/2hour.  I just  judge a uniform covering by eye, and use a pebble to mark where I last stopped, and in what direction I was heading . It's not super-critical.

    Lawns only.  It will stain hands and surfaces, and rot clothes.

    @jonny_supersonics what you should have done is filled your sprayer with water and then gone over your lawn spraying the water out doing only 1 pass.  Once you have done this see how many litres of water you have used and times by 3.  This number is the number of litres you need to fill your sprayer with.  You then add the 588g of product to the sprayer and spray your lawn making 3 passes (until the sprayer is empty).  Voila, you’ve treated the whole lawn.

    Let's say 600g.  That's a lot to be dissolving in one small sprayer.
