How well do they work? I'm talking about the ones you just stick into the ground and they give you a reading of the soil pH. Also i've seen a fertilizer analyzer that is supposed to give you a composite reading of nitrogen, phosphorus, and potash. How do those work?

What is the best way to know what/how much fertilizer a lawn needs?

The best ways to know how much fert your turf needs in a given year is to do a soil test. Also you have to know what species of turf you are dealing with. Fescues only need 1 - 2 lbs of N per year, whereas Bentgrass, Bluegrass, and Ryegrass need 3 - 5 lbs of N per year.

I have used them before in contanier plantings. I got a reading, so I guess they work. I would not use it for large areas(soil test)
