Methods

Method ID: 1
Name: Near Infrared Spectroscopy
Description: Samples were dried at 70oC, and ground to pass a 1mm mesh screen. The dried and ground sample was scanned using a NIRSystems spectrophotometer. Foliar N, lignin and cellulose concentrations were predicted from the resulting spectral signatures.

Method ID: 2
Name: ICP Analysis
Description: Digestate was analyzed for Al, Ca, Fe, K, Mg, Mn, P and Sr using an inductively coupled plasma spectrometer.

Method ID: 3
Name: TKN digestion
Description: Samples were dried at 70oC, and ground to pass a 1mm mesh screen and digested using a modified TKN digestion using a selenium catalyst (Isaac and Johnson 1976).

Method ID: 4
Name: Microwave digestion
Description: Samples were dried at 70oC, and ground to pass a 1mm mesh screen. Dried and ground foliage was digested using a microwave assisted acid digestion procedure.
