АНАЛИЗ НА ЛЕСОРАСТИТЕЛНИТЕ СВОЙСТВА НА АЛУВИАЛНИ ПОЧВИ В ПРЕДПЛАНИНСКАТА ЧАСТ НА ИЗТОЧНА СТАРА ПЛАНИНА, БЪЛГАРИЯ

Abstract

Soil fertility determines the guidelines for the development and normal functioning of forest ecosystems. This emphasizes the need to analyze the silvicultural properties of the soil, expressing its fertility in terms of forest tree vegetation. The characteristics of alluvial soils (Alluvial Fluvisols) correspond to the Fluvisols soil group in World Reference Base for Soil Resources (2022). Тhe paper presents an analysis of the silvicultural properties of alluvial soils in the foothills of the Eastern Balkan Mountains. After direct studies on the soil properties and analysis of the growth and productivity of the respective plantations, the soils were grouped into two bonitat groups - high fertility and low fertility.
