NIR/Vis Soil Test 2

Overview

Using the MultispeQ with modified detector placement we are trying to see if the reflectance wavelengths can be used to differentiate between different soil types or identify composition.

We have soils from Kenyan sites at different depths ranging from 0-15cm to 100-200cm with different levels of total and black carbon (% w/w). We'll use these to see how well the MultispeQ can predict total and black carbon wavelengths. Black carbon has been indicated as an important of soil carbon stability and nutrition retention. In addition to already managed sites with high levels of black carbon, like the Terra Preta de Indio, black carbon, or biochar, is being used in current soil management strategies.

In addition to the soil samples with different levels of black carbon, we'll test standard samples made with a mixture of activated carbon (black carbon), cellulose, lignin, and silica. These will be used to try and test how well the MultispeQ detects different forms of carbon.
