Production and statical stability of the fir (Abies alba Mill.) root system

Production and statical stability of the fir root systems in 15 areas under optimal growing conditions were investigated. Three hundred and twenty-four root systems of trees pulled down by the wind and 30 from standing trees were measured. Size of a root system (length, width), its spread and diamet...

Summary:Production and statical stability of the fir root systems in 15 areas under optimal growing conditions were investigated. Three hundred and twenty-four root systems of trees pulled down by the wind and 30 from standing trees were measured. Size of a root system (length, width), its spread and diameter in different soil types, rooting, health conditions and physical and mechanical soil features were investigated. Results document that the most important condition for growth and distribution of roots is the availability of underground water. The growth of fir roots is limited by the age of 100 years while the taproot need not necessarily be developed. The total below-ground biomass in soils rich in minerals was 27.3 t per ha. In poor soils the total amount of below-ground biomass was higher - 33.6 t per ha
