Why to Use Visible-Near Infrared Spectroscopy to Determination of Soil Organic Matter
Millions of soil analyses are performed every year around the world to increase crop yields. However, the two main conventional methodologies to determine the SOM (Walkley–Black and dry-combustion) are time-consuming and expensive, and hence are not suitable for use on a large scale. Also, the Walkley–Black method is damaging to the environment. Therefore, why could use visible-near infrared spectroscopy?
