Abstract
The aim of the research is to develop a digital monitoring methodology for agro-ecosystem indicators based on space and unmanned technologies with the conversion of digital aerial photography results into real parameters of agrophytocenosis indicators as physical units. The paper uses the results of research on digital monitoring of agrophytocenosis of single- and poly-species crops of grain and leguminous crops on the experimental field of the Samara State Agrarian University in 2018 (southern forest-steppe of Trans-Volga region). The soil is a typical medium heavy black loamy chernozem (humus content is 5.9 %, easily hydrolysed nitrogen is 80–120 mg/kg, labile phosphorus is 135–145 mg/kg, exchangeable potassium is 150–195 mg/kg, salt extract pH is 6.9). The research conducted in 2018 revealed that the stated aim is achievable in principle. According to the results of 2018, the greatest correlation between the vegetative biomass index NDVI and grain yield for winter and spring cereal crops was detected at the milky stage of the grains (up to r = 0.82).

The aim of the research is to develop a digital monitoring methodology for agro-ecosystem indicators based on space and unmanned technologies with the conversion of digital aerial photography results into real parameters of agrophytocenosis indicators as physical units
We performed digital monitoring using the method of obtaining high-resolution images at different crop vegetation stages using unmanned aircraft systems (UAS) using vegetation indexes, including the biomass index (NDVI)
Summary
In 2018, the national project “Digital Economy” was adopted in Russia at the national legislative level. It was one of thirteen Russian national projects for the period from 2019 to 2024 (the passport of the project was approved by the decision of the Presidium of the Presidential Council on Strategic Development and National Projects on December 24, 2018) [1]. The national project "Digital Economy" was created to solve, among others, the following problems: the transformation of priority sectors of the economy and social sphere, including health care, education, industry, agriculture, building construction, urban economy, transport and energy infrastructure, financial services, through the introduction of digital technology and platforms. Digital monitoring of agroecosystem indicators is carried out on the basis of assessment of crop variability by vegetation indexes, using aerial photographs on a multispectral camera
