Aerospace information gathered by different sensors and Earth observation missions has become an undoubted
necessity in various investigation and application fields. Remote sensing data address many world significant
problems such as ecosystem change detection, natural resources management, environment preservation, etc.
Vegetation monitoring is among the priorities of these investigations being the most important component of the
biosphere. In agriculture remote sensing applications are associated with plant growth assessment, stress detection,
yield forecasting. This paper is devoted to the relationships between agricultural vegetation spectral and biophysical
features with consideration of some growth conditions. The influence of soil properties and anthropogenic factors
(fertilization, heavy metal pollution) on crop spectral response has been examined in relation to the applicability of
spectral models to estimate plant variables and assess crop state and stress impacts.
