A Measuring and Analyzing System for Spectral Response in Soils Ranging from Visible-Near infrared Band

摘要

This paper introduces mainly the structures and the functions of the instrument for analyzing rapidly soil composition based on spectral measuring techniques. This measuring system can be used to measure soil spectral properties with a response range from 400 to 2900nm. On the basis of these, we studies the reflective spectrum of soil organic matter and evaluates primarily the repeatability and stability of the system in the practical measuring.
