Looking for some advice. Got icp test results back can anyone explain how phosphorus can be so low but phosphate is so high i thought the 2 were directly linked as i use a hanna checker phosphorus ulr and convert to phosphate with the following formula.
Phosphorus ppb x 3.066 ÷ 1000 = phosphate ppm. attached is the icp and my own test results from same sample.
