use of spectral reflectance values for determining nitrogen, phosphorus, and potassium contents of rangeland plants
this study was carried out to determine nitrogen, phosphorus, and potassium contents of rangeland plants using spectral reflectance value. the measurements were made in 1 m2 area of different parts of a rangeland. a portable spectroradiometer capable of measuring the wavelength range of 325-1,075 nm of the electromagnetic spectrum was used to collect spectral data. spectral measurements were ma...
متن کاملPrecise Analysis of Spectral Reflectance Properties of Cosmetic Foundation
The present paper describes the detailed analysis of the spectral reflection properties of skin surface with make-up foundation, based on two approaches of a physical model using the Cook-Torrance model and a statistical approach using the PCA. First, we show how the surface-spectral reflectances changed with the observation conditions of light incidence and viewing, and also the material compo...
متن کاملSpectral reflectance properties of carbonaceous chondrites: 7. CK chondrites
The reflectance spectra of 15 CK chondrites have been measured as part of an ongoing study of carbonaceous chondrite reflectance spectra. The available sample suite includes multiple grain sizes and samples with petrologic grades varying from CK4 to CK6. CK reflectance spectra are all characterized by an olivineassociated absorption band in the 1.05 lm region. Compared to pure olivine, CK spect...
متن کاملEstimating Chemical Properties of Florida Soils Using Spectral Reflectance
This study was conducted to develop fundamental relationships between soil properties from three representative Florida soil orders and their spectral characteristics. The ultimate goal of this work is to develop a real–time soil property sensor for use in effective farm management. A total of 270 samples collected from the three representative soil orders (Alfisol, Entisol, and Ultisol) in Flo...
متن کاملSpectral reflectance properties of carbonaceous chondrites: 1. CI chondrites
Existing reflectance spectra of CI chondrites (18 spectra of 3 CIs) have been augmented with new (18 spectra of 2 CIs) reflectance spectra to ascertain the spectral variability of this meteorite class and provide insights into their spectral properties as a function of grain size, composition, particle packing, and viewing geometry. Particle packing and viewing geometry effects have not previou...
