Description

In order to increase food production and to avoid injuries for the environment, agriculture and farming researches have to be enlarged. Regarding soil degradation, the identification and characterization of organic matter, as well as its qualitative evaluation, have been made by nuclear magnetic resonance (NMR), electron spin resonance (ESR), infrared spectroscopy, and others. This work has evaluated humic acids structure and properties using 13 C NMR techniques and compared several kinds of soil handling. NMR spectra were presented and analysed and the results discussed
