Агрохимические свойства почв коллекционных питомников Полярно- альпийского ботанического сада

Abstract

The current state of soil fertility was estimated at 2 sites of experimental fields of the Polar-Alpine Botanical Garden. Soils in both areas are characterized by a light granulometric composition. The sites vary in the content of organic matter in the soils, as well as the acidity and proportion of the sites where the liming is needed. The availability of phosphorus at all sites in both areas is characterized as high, potassium — from medium to high, mineral forms of nitrogen — as very low.
