Producing compost with consistent stability and maturity is critical for the successful marketing of compost as
part of growth media. Therefore, simple and effective method for determination of maturity and stability of
compost is needed. Near infrared spectroscopy (NIRS) allows rapid simultaneous determination of chemical and
physical properties of organic materials. The previously developed NIRS model in which NIR spectral data were
combined with various parameters describing degradability and stability of composts during the composting process
(respirometric, photometric, C / N extraction, Solvita™) using well known maturity test and chemical analyzes. This
model was used for analysis of compost samples from various composting sites with different technologies and with
different composition of starting materials. The measurement revealed that NIRS method .. View more»
