Influence of fertilizers on agrochemical properties of produced up-moor peat land under large-fruit cranberry virginil plants in Belarus

The article presents the results of a comparative study in 2020 and 2021 in the Smolevichi district of the Minsk region and in the more northern Dokshitsy district of the Vitebsk region, geographically 250 km from each other, in an experimental culture on reclaimed areas of high-moor peat production of the effect of mineral Basacot Plus 6 (N₁₅P₈K₁₂ kg/ha active ingredient) and domestic biological fertilizers – nitrogen-fixing and phosphate-mobilizing microbial MaKloR in 5 % and 10 % concentrations, as well as organo-mineral Ecogum-complex on the agrochemical properties of the substrate under plantings of early-ripening Ben Lear and late-ripening Stevens varieties of large-fruited cranberry within the framework of identical field experiments. It was established that in both seasons all the tested agricultural practices contributed to its noticeable enrichment with nutrients compared to the control, while the degree of this enrichment was determined by the geographical location of the study area, weather conditions of the growing season, the genotype of the experimental plants and the stage of their seasonal development. Nevertheless, regardless of all the indicated factors, in most cases the most effective in increasing the level of substrate fertility was the introduction of mineral fertilizers, and among biological fertilizers – the use of Ecogum-complex and 5 % MaKloR.
