Using the Kjeldahl nitrogen determination method, first measure the nitrogen content of the organic matter in the sample, then multiply by 6.25.
--------------------------------------
The principle behind crude protein determination is basically the Kjeldahl nitrogen method; it is just that using instruments makes it more convenient, and the error can be reduced accordingly.
