To increase the organic potato yield, it is necessary to provide the crop with sufficient nutrients and effective means of biocontrol the diseases. The research goal was to characterize the biorationals’ efficacy to achieve competitive organic potatoes’ yield under various weather conditions. A 4-year trial was carried out in the Leningrad region using Udacha variety potatoes. The tests used liquid forms of new polyfunctional biologicals Kartofin based on highly active Bacillus subtilis I-5-12/23 and organic fertilizer BIAGUM obtained from poultry manure by aerobic fermentation in a closed biofermenter. Significant stimulation in plant growth and development to the flowering phase regardless of the hydrothermal conditions of the growing season was noted. The stimulating effect was determined by the combined use of biorationals pro rata to BIAGUM dose. Kartofin biologicals and BIAGUM almost doubled the potato tubers’ yield compared to the control, regardless of the growing season conditions. At the flowering phase, the biological efficacy in potato fungal diseases incidence and development was near 90% under optimal and 50–75% under drought hydrothermal conditions. At the end of vegetation, the efficiency in fungal diseases incidence and development made up 45–65% under optimal and 45–70% under dry conditions. BIAGUM effectiveness in reducing disease development reached 45–50% regardless of growing season conditions.

In September 2015, the UN General Assembly adopted 17 goals and 169 targets for sustainable development until 2030. The fourth goal provides for the development of inclusive and equitable quality education, and goals 12, 13 and 14 are aimed at protecting the environment and organizing appropriate education for this. When implementing environmental education, it is necessary to take into account the characteristics of a generation of students, in this case, generation Z. For a number of years, Russian-Finnish projects were carried out in the Luga district of the Leningrad region. One of the main objectives of the projects concerned the environmental education of schoolchildren and students. Using international experience, a number of interactive teaching methods have been developed and are still being used. They are focused on fostering student independence and provide his motivation. A student conducts his own research work and participates in a youth team to prepare and to implement their own projects aimed at solving local problems. This approach forms an ecological culture of an ecocentric type among students, and their desire to bear their part of responsibility for the state of the environment.
