摘要
The biodegradation evaluation method determines the nitrogen or carbon available for plant nutrition by measuring the content of the latter in the soluble and non-soluble organic substances, with determination of the overall organic carbon content, with determination of the soil breakdown characteristics by measuring the soil texture and the water capacity, in combination with climatic factors. An analytical soil sample is subjected to reflection and/or transmission spectroscopy with a wavelength range between 400 nm and 2500 nm, with evaluation of the absorption values by comparison with the values for chemical analysis fractions.
