The article is about a problem of improving the quality of foam layer parameters recognition in potash flotation machines. The urgency of the problem has recently been emphasized by the need to strengthen Russia's food security, for which, in particular, potash fertilizers are required. The glare method of recognizing the parameters of the foam layer in potash flotation machines makes it possible to eliminate the human factor from control, improve product quality and reduce waste. However, it has a number of disadvantages – a large spread of results, sensitivity to the organization of lighting, etc. The aim: to improve the quality of foam layer parameters recognition by taking into account not only glare, but also anti-glare from bubbles. Materials and methods. Anti-glare is recognized by two-level adaptive binarization of the image. Dozens of video sequences were processed from slurry, silvin and pneumatic ejector flotation machines on two potash enterprises. The possibility of linear approximation of not only the upper one, but also the lower level of binarization is investigated. Binarization profiles for additional recognition of glare and anti-glare are constructed. Results. The possibility of using anti-glare bubbles to improve their recognition by an average of 3.6% is shown. The greatest increase in quality is achieved on pneumatic ejector flotation machines. The estimation of the average deviation suggests that the accuracy of alarm deviations due to noise reduction will improve by 1.4–4.8%. The anti-glare profiles character shows that a small shift in the adaptive level of binarization can further improve recognition in the range of 0.6–1.5%. The characteristic features of the method are revealed, for example, its superiority over the original glare method in the sense of a lower sensitivity to the error of calculating the binarization level. The double increase in recognition time is a disadvantage of the method, but it does not prevent one’s using, including using of multi-frame noise filtering. Conclusion. The conducted research suggests that taking into account the anti-glare bubbles when recognizing the parameters of potassium foam flotation machines can improve the process performance and can be applied in practice, preferably for pneumatic ejector machines.

This article presents the results of a 3-year research study into the effect of soil and foliar application of nitrogen and potassium fertilizers on the taste qualities of the Veniaminovskoe (Rvi6) and Sinap Orlovskii (3×) apple varieties bred at the Russian Research Institute of Fruit Crop Breeding (VNIISPK). The assumption that varietal features are the most important factor that determines taste was confirmed. In addition, the influence of weather conditions of the growing season on the chemical composition of fruits was observed. Thus, the year of 2019 was characterized by the most favorable weather conditions of the growing season. In August, during fruit ripening, the optimum temperature and humidity regime had a positive effect on the accumulation of soluble solids, sugars, and titratable acids in both varieties under study. However, the varieties responded differently to the same doses of mineral fertilizers. The application of fertilizers had no significant impact on the content of the studied components and the sugar-acid ratio in Veniaminovskoe fruits. Conversely, Sinap Orlovsky was found to be responsive to this agricultural practice. In 2019, the joint application of triple foliar and soil fertilizing using N30K40, N60K80, and N90K120 in various doses had a positive effect on the reduction of titratable acidity in fruits of this variety. As a result, the sugar-acid ratio increased by 1.3–1.9 times. Over the entire study period (2017–2019), a significant decrease in the content of sugars in Sinap Orlovsky fruits was observed in the variant with additional foliar fertilizing compared to the control. During the study period, the high doses of N90K120 nitrogen and potassium fertilizers along with foliar application contributed to a significant increase in the sugar-acid ratio in Sinap Orlovsky fruits, which significantly exceeded the control.
