Popis: | An integrated approach based on satellite remote-sensing data and the results of analysis of mathematical models has been tested for applicability in the evaluation of crop yield and total phytomass of agrocenosis, as well as identifying its type. The dynamics of the normalized difference vegetation index (NDVI) and the total aboveground phytomass of agrocenosis proved to be qualitatively similar. An analysis performed using a mathematical model and taking into account air temperature showed the possibility of making and refining the prognosis of crop yield. In this course, the vegetative and generative parts of the agrocenosis were distinguished, and it was found that model data matched ground survey data under optimal environmental conditions. |
