Molecular properties of a fermented manure preparation used as field spray in biodynamic agriculture [R. Spaccini, P. Mazzei, A. Squartini, M. Giannattasio & A. Piccolo, 2012]
Abstract Manure products fermented underground in cow horns and commonly used as field spray (preparation 500) in the biodynamic farming system, were characterized for molecular composition by solid-state nuclear magnetic resonance [13 C cross-polarization magic-angle-spinning NMR (13 C-CPMAS-NMR)] spectroscopy and offline tetramethylammonium hydroxide thermochemolysis gas chromatography-mass spectrometry. Both thermochemolysis and …
