I just bought a soil test kit for pH, N, P, and K. But I am extremely confused on how it works.

I put the soil in the thing to the line, then I filled with water to the other line, opened a capsule and poured it in with the water and soil mix, then put the lid on and shook it up.. The color was hard to determine with all the soil floating around, from what I could decipher it looked like 6, 6.5 or even 7.. hard to tell. If I had to take an honest guess the color was like 6.5 maybe a little bit higher or lower.

How accurate is this? Did I do it right?

did it come with instructions?

Yeah, instructions that weren't clear at all. I know it doesn't take rocket science to test pH, but I have never done it before.. and I know someone here has.

I might just go buy a 4-way analyzer tomorrow at home depot or something.. even though I dropped $18 on this lame test kit.

I havent used one myself, but I have managed to find some instructions in pdf form for taking the soil samples and how to read them

For soil testing you should just get one of these meter things.. they are cheap and accurate. It cost me about $8 USD at Home Depot.
