The article presents the results of studying the influence of organo-mineral fertilizers and establishing an effective dose on the physiological processes of growth and development of Pýrus ussuriēnsis L., introduced into the urban environment.The experiments were conducted on the territory of the Astana Botanical Garden in three areas.The test object was the fertilizers "KazUgleGumus" and "Agrarka".The first fertilizer was obtained from brown coal, the secondby enriching processed bird droppings with microorganisms.Of the two types of fertilizers we used, "KazUgleGumus" showed greater efficiency due to its rich content, including organic humic acids and natural minerals (Ad; Wr; Vd; St; Сt; Нt; Nt; Na; Al; K; Ca; Ti; Fe; Zr).A comparative analysis of the effective doses of the fertilizers used showed that the trees responded best to the effect of the humate fertilizer "KazUgleGumus" at a dose of 1.5%, and "Agrarki" at a dose of 1%.This result indicates the need to study the physicochemical composition and properties of soils and microbiocenoses on the territory of the botanical garden.
