Someone asked what is the total nitrogen value (ie. the N of NPK) of the SoyAmino come from?
According to Food and Agriculture Organization of the United Nations: http://www.fao.org/3/Y5022E/y5022e03.htm
the nitrogen content conversion factor for soybean amino acid/protein is 5.71. So, to convert the 9-% amino acid in SoyAmino AA90 we 90/5.71~=15.76%. To be modest we claim the NPK as 15-0-0 on our label.
