Soil analysis using visible and near infrared spectroscopy.
Visible-near infrared diffuse reflectance (vis-NIR) spectroscopy is a fast, nondestructive technique well suited for analyses of some of the essential constituents of the soil. These constituents, mainly clay minerals, organic matter and soil water strongly affect conditions for plant growth and influence plant nutrition. Here we describe the process by which vis-NIR spectroscopy can be used to...
متن کاملMapping polycyclic aromatic hydrocarbons and total toxicity equivalent soil concentrations for hazard assessment by visible and near infrared spectroscopy
In a previous study, we have shown that spectroscopic models based on visible and nearinfrared (vis-NIR) spectroscopy (350–2500 nm) predicts polycyclic aromatic hydrocarbons (PAHs) in tropical rainforest soils with reasonable accuracy. In this study, we used these models to develop soil maps of PAHs and total toxicity equivalent soil concentrations (TTEC) of the PAH mixture. We used the soil ma...
متن کاملIn Situ Measurement of Some Soil Properties in Paddy Soil Using Visible and Near-Infrared Spectroscopy
In situ measurements with visible and near-infrared spectroscopy (vis-NIR) provide an efficient way for acquiring soil information of paddy soils in the short time gap between the harvest and following rotation. The aim of this study was to evaluate its feasibility to predict a series of soil properties including organic matter (OM), organic carbon (OC), total nitrogen (TN), available nitrogen ...
متن کاملPossibilities of visible–near-infrared spectroscopy for the assessment of soil contamination in river floodplains
During the past decades, large amounts of diffuse cadmium (Cd) and zinc (Zn) contaminated soil material have been deposited in the floodplains of the river Rhine in the Netherlands. As spatial information on soil quality is required at different scale levels covering the whole area, characterisation exclusively based on soil sampling and analysis is time-consuming and very expensive. A quicker ...
متن کاملPrediction of Soil Organic Carbon at the European Scale by Visible and Near InfraRed Reflectance Spectroscopy
Soil organic carbon is a key soil property related to soil fertility, aggregate stability and the exchange of CO2 with the atmosphere. Existing soil maps and inventories can rarely be used to monitor the state and evolution in soil organic carbon content due to their poor spatial resolution, lack of consistency and high updating costs. Visible and Near Infrared diffuse reflectance spectroscopy ...
