[QUOTE="sjt01, post: 7604148, member: 30726"] P and K will come out of the digester just as they went in. Nitrogen can be lost as ammonia from the digestate, as it is high pH. I am not sure what the pH of pig muck is, but the losses are probably comparable. You might lose a bit of sulphur, depending on how the reactor is run. We are now acidifying our digestate to stop the ammonia loss, I have not had the final analysis done but I think we will have about 25% more N than untreated. [/QUOTE]
