Hi, have used a rapid nutrient analyser set that was made by the National Vegetable Research Station for doing pH, N,P and K analysis of soils for a good few years now but am starting to run out of certain powder and reactants. Can get barium sulphate easy enough for pH but am struggling to find any of the others for P and K. Tried few different agronomist, grain traders, grass seed guys but no luck. They were more interested in doing it for me for a small charge of course! Anyone know where they could be sourced? Cheers
