Soils are the basis for human civilization by providing for food, fiber,\nand fuel production, additional ecosystem services such as water filtration and\nstorage, and a foundation for our roads and buildings. As world population is\nestimated to increase from around 7.3 billion to 9.8 billion by 2050, soils\nwill be under increasing pressure to continue to provide essential services for\nboth human and natural ecosystems. Several different national and international\nframeworks have been proposed to assess and monitor soil health and degradation\nin order to better inform land users and policy makers for protecting our soil\nresources.<\/p>\n\n\n\n

The soil is a mixture of organic and mineral solid compounds together\nwith liquid and gas phases. This results in a complex assemblage from the\nmolecular to global scale. Traditionally soil studies would involve measuring\nmultiple physical, chemical, and biological indicators to classify the soil and\nexamine dynamic soil properties such as organic carbon. Especially for large\nnumbers of samples for national surveys and for repeated monitoring\nmeasurements, the time and cost for these analyses can be prohibitive. <\/p>\n\n\n\n

An alternative to traditional costly and laborious soil analyses is\ninfrared spectroscopy. Infrared spectroscopy relies on vibrations of different\nmolecules which can provide both qualitative indicators of different compounds\nand then be statistically correlated to traditional soil analyses via modeling\nfor quantitative estimates. The soil can be sampled, minimally prepared, and\nthen scanned with an infrared spectrometer, which only takes 1-2 minutes. The\nmeasurement itself is non-destructive so the sample can be reused for other analyses.\nOnce a prediction model has been developed for a certain area, then just the\nspectrum from that soil needs to be measured. Infrared spectroscopy has shown\nto be able to predict a wide range of properties, but in most cases local or\nregional predictions models need to be constructed. <\/p>\n\n\n\n

This presentation will examine the feasibility of infrared spectroscopy\nfor the rapid prediction of soil properties for assessing and monitoring\ndegradation in the context of Armenia. The work represents a collaboration with\nThe Center for Ecological and Noosphere Studies.  <\/p>\n\n\n\n
