The use of reflection spectra in recognition of crops

The Fine Structure of the Solar Spectrum and Evolution of The Biosphere

“…We propose to measure solar radiance in Fraunhofer lines during pollution episodes, in order to get information on a potential threat to plants. Our earlier, background studies include the one cited above and Kondratyev et al (1986aKondratyev et al ( , 1986bKondratyev et al ( , 1987.…”

“…New precision farming techniques in agriculture can be used more accurately to assess crop growth and soil conditions during growing seasons [1][2][3][4][5]. New high accuracy GPS satellites used for position control, e.g., the new EU-funded GALILEO system [6], and new hyperspectral spectrometers operating over a wide range of wavelengths (λ = 400-2,400 nm) provide new possibilities and tools for cereal cultivation [1,[7][8][9].…”
