Hello Dear
We are going to create a machine learning model that will predict NPK values without any lab testing. For model creation, we have to test 200+ soil samples. P and K have been found through XRF. However we need 2,6-Dimethylphenol (2,6-xylenol) for NItrogen's amount finding. 
I kindly request the company to please update me about the current prices and discounts offered.
Thanks You
