Study of the influence of organomineral fertilizer- ameliorants based on natural aluminosilicates and biologically active substances on the growth of Phaseolus vulgaris. Part 2.

The study presents the results of investigating the influence of novel organomineral fertilizer-ameliorants based on expanded vermiculite and biologically active substances (humic substances, the microalga Chlorella vulgaris, and an animal-derived protein hydrolysate) on the growth of common bean (Phaseolus vulgaris). Pot experiments were conducted on degraded soils of the Otyrar district of the Turkestan region. It was demonstrated that the application of the fertilizer-ameliorants promoted an increase in total biomass, root mass, leaf number, and plant height compared to the control. The Vermi-KB treatment produced the most pronounced effect, leading to an 80.6% increase in plant dry biomass compared to the control. The use of Vermi-CV also showed a pronounced positive result (an increase in raw biomass by 58.0%). The results confirm the effectiveness of the developed fertilizer-ameliorants and their potential for increasing the fertility of degraded soils.
