Spectrochimica Acta part B 58: 767-782. [ Links ] He, Y., M. Huang., A.G. Pereira., A.H. Gómez, and H. Song. 2007. Prediction of soil macronutrients content using near-infrared spectroscopy. One hundred and fifty six soil samples from the humid tropics of Tabasco, Mexico with contrasting chemical characteristics were selected. Are these correct, and can you give more detail as to how these were collected? The result is an extensive portfolio of NIRS laboratory and process spectrometers as well as ready-to-analyze Raman spectrometers in smartphone size.
The standard mathematical treatment, MSC 2, 10, 10, 1 (multiplicative scatter correction), had a higher R2 and the least standard error of calibration (SEC) and standard error of cross validation (SECV). Figure 3 depicts to the average coefficients spectrum generated with this model. Soil and Tillage Research 70:1-18. [ Links ] Ludwing, B., P.K. Khanna., J. Bauhus, and P. Hopmans. 2002. Near infrared spectroscopy of forest soils to determine chemical and biological properties related to soil sustainability. These samples were sampled and evaluated similarly to those of the calibration group; the model chosen for each case was used, and SOM was calculated. Our expertise in spectroscopy goes back more than 50 years and is evidenced by numerous patents.
However, I could not find his explanation by searching for ‘Norris’. Karl, please help us! Seen by many as the industry standard, they are used throughout the animal feed industry to control and segregate incoming raw material, control consistency in feed production and ensure finished products are in line with the demands of customers and the authorities.
