Capital Investments in Transportation Must Be Increased
>p>During the current seven-year period it is intended not only to fulfill tasks relating to production volume, but also to prepare all areas of the economy for further rapid advances.>/p>>p>We inherited a quite developed rail transportation plant from the Tsarist regime, but a meager scale of per capita production. In pre-Revolutionary Russia, transportation was the largest recipient of basic funds. In contrast, roughly 13 per cent of all capital outlays under the first, second and fourth five-year plans was directed to railway transport.>/p>>p>During the current seven-year period it is contemplated to pour 110-115 billion rubles into railway transportation development, which is 5.5 per cent of the total capital investment in the national economy as a whole.>/p>
Digital monitoring of agro-ecosystems indicators on the basis of space and unmanned technologies
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)
