K removal in barley straw

Q & ACategory: QuestionsK removal in barley straw
Tom Shaw asked 3 months ago

Hi,
I have identified three different sources which give me three different answers for the amount of K removed in 1 t of barley straw. I have a document from Landmark that tells me that I will remove 5 kg/T, a GRDC barley grow notes document that tells me 10-11 kg/T, and the IPNI calculator that tells me 16.6 kg/T.
Which of these is correct and why?
Regards,
Tom

Australian Soil Fertility manual quotes 12kg/t for cereal hay.
