Field-portable visible/near-infrared spectrophotometer for mapping soil carbon in Canada's ecosystems

我们正在请求一种实地便携式仪器，用于测量土壤剖面中可见光和近红外辐射的反射率。 该仪器称为可见/近红外（维斯/NIR）光谱仪探头。 该探头可以准确地评估土壤中的土壤碳含量，并且只需将探头插入土壤即可使用。 由于该仪器可以快速且免费地测量土壤碳，因此它将使我们能够在北极，省北部和农业生态系统中构建非常精细的土壤碳地图。 我们需要这样做，因为土壤碳在不同的领域变化很大，使用传统技术获得精确的估计需要大量的样本，这是昂贵和耗时的。 相比之下，这个探测器将允许我们在一个下午完成几周的实验室分析工作。

We are requesting a field portable instrument that measures the reflectance of visible and near-infrared radiation down a soil profile. This instrument is called a visible/near-infrared (VIS/NIR) spectrophotometeric probe. This probe can accurately assess soil carbon contents in a soil and is used by simply inserting the probe into the soil. Because this instrument measures soil carbon very quickly and at no cost, it will allow us to construct very finely detailed maps of soil carbon in the Arctic, provincial Norths and agricultural ecosystem. We need to do this because soil carbon varies quite a bit across a field and getting a precise estimate using traditional techniques requires a large number of samples which are costly and time consuming. In contrast, this probe will allow us to do the work of a few weeks of laboratory analysis in an afternoon.
