Effect of Microbial Fertilizer “Biotilia” on Urban Soil Microbiome and the Vitality of Horse Chestnut Exposed to Salinization

Abstract

The data provides the results regarding the effect of the microbial fertilizer “Biotilia” on the microbiome and agrochemical properties of the upper soil layer surrounding horse chestnut trees growing along the central Minsk highway and exposed
 to deicing agents in winter. It was found that application of microbial fertilizer, retained in the soil throughout vegetation season, raised population of halotolerant bacteria and microorganisms involved in the conversion of nitrogen and phosphorus in the soil microbial cenosis. Evaluation of agrochemical properties of soils revealed decreased in the content of chloride ions and sodium cations, increased the
 amount of mobile forms of nitrogen, phosphorus, potassium and calcium, which ensures the general physiological resistance of trees to soil salinization.

Cultivation of halotolerant bacteria as a basis of the microbial fertilizer “Biotilia”

“…Данные, полученные в ходе отработки параметров культивирования штаммов Rh. jostii СА-6 и P. megaterium Ср-1 в производственных условиях, использованы для разработки технологии получения микробного удобрения «Биотилия», предназначенного для минимизации негативного влияния противогололедных реагентов на городские насаждения и улучшения роста растений в условиях засоления [11].…”
