摘要
Method for evaluation of content of nitric fertilizers in earth includes use of dependence of parameters of leaf of plant that grows on earth with nitric fertilizers brought in on concentration of those fertilizers. Besides that one measures dependence of reflection spectra of grean leaf on concentration of nitric fertilizers in earth with determination of reflection spectral index r(N)=[r(830)-r(660)]/[r(830)+r(660)] (where 660 nm and 830 nm analytical wavelengths) that correspond to optimal area of concentration of nitric fertilizers.
