Background and aim The processes of nitrogen (N) mineralization from organic amendments (OA) is important to provide mineral forms (NH₄⁺ and NO₃⁻) of N for plants. Assessment of N mineralization is ...

In order to identify and quantify reaction products, a variety of analytical methods are used. These reaction products include mass spectrometry, chromatography, nuclear magnetic resonance (NMR) ...

Man-made chemical treatments like chemical pesticides, fertilizers, and herbicides are not used to grow organic coffee. The soil is enriched with the utilization of manure, compost, and crop rotation ...

Nuclear Magnetic Resonance (NMR) was first experimentally observed in late 1945, nearly simultaneously by the research groups of Felix Bloch, at Stanford University and Edward Purcell at Harvard ...

For the majority of users conducting nuclear magnetic resonance (NMR) spectroscopy today, sample preparation follows a similar path: isolate a compound or compounds from a reaction mixture (or if ...
