Abstract
A rapid and simple method of quality measurement for compost was developed using an FT-NIR technique. Compost samples collected from a composting factory were used for the calibration and validation of components. NIR spectra were measured within the range of 1000-2500nm. Total carbon (TC) and total nitrogen (TN) were measured by N/C Analyzer and mineral contents measured by an Inductively Coupled Plasma (ICP) instrument for calibration and validation. Partial least square regression and multiple linear regression were employed for calibration among the second derivative spectra and measured the mineral content. The calibration models evaluated correct contents of potassium, phosphorus and other minerals of the test composts in received accuracy. These results indicated that NIR spectroscopy was a useful tool for the management of compost quality.
