You are correct. I punched 3.6 ppt into an online converter and it gave me 0.0000036 ppm. Just put it in a different one and it’s 3600. Maybe it was using parts per trillion?? Didn’t even think to check that. Makes a lot more sense that the EC reading is 5120 now. I took calculus classes for electives in college but now I use a smartphone calculator for addition. SMH.
This question is for anyone that can answer it. Do you need to measure runoff when using dry amendments? How do you know if you need to add more or added too much? or just use them on a schedule?
