hi all
I just got my soil test back but I need some help to convert the numbers to ppm , soil labs says that results are in mg/100gr ( 100 gr being the soil)
anyone know how to convert his?
and yes Amelio even your help would be appreciated
thanks

Are you sure the results are not in mg/1000g? 1 mg per 1000g is 1 ppm. 77 ppm P sounds reasonable but if it is mg/100g it would be 770 ppm which is not likely.

Rohhny, deel het door 0.502

dus je bedoelt alle resultaten x 0.502 ?
als dat waar zou zijn is er nog veel werk aan de winkel
merci for de info
and thank you Amelio will certainly get back to you on this topic

Niet vermenigvuldigen. Delen, 77 : 0.502 = 153.38 ppm

well got an e-mail bacl from soil lab and they say you have to do all results X 10

ppm = mg/L or mg/1kg DM

ppm (part per million), is like %, you have to compare same things, weight to weight, volume to volume etc. The advice to multiply by 10 is right.

The labs we have here are giving results in mg/L, and then the conversion should take into account the density of the soil. For mineral soils 1:1 can be used so, ppm is the same as mg/l to get to the ballpark. But that is a different subject.

I,m not confusing you more, the lab's advice is right.
Your P seems to be extremely high...but I'm no expert.
