1st International Electronic Conference on Forests, 15–30 November 2020

Aim of the project: Protection of soil fertility and biodiversity

➢ Determination of current nutrient pools and fluxes of different forest sites

➢ Estimation of expected nutrient removals during wood extraction

➢ Derivation of nutrient balances

➢ Formulation of management recommendations

Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) |1st IECF | 15–30 November 2020

Material and methods: Real data from case study areas and modelling

Soil analyses

• pH-value

• Ca, Mg, K, Na, Mn, Fe, Zn

• N-, S- and P-content

• carbon(org)-content

• weathering rate

• deposition

• soil leaching

Decision Support

• Derivation of

nutrient balances

• Formulation of management

recommendations Case study areas

1) Bülach (CH)

2) Buch a.Irchel (CH)

Simulation

• alternative forest management

strategies

• forest stand

development over rotation period

• nutrient removal due to extraction

Outlook: Development of nutrient database and software

➢ Application of method to overall Switzerland

➢ Implementation of site-specific nutrient-balances in forest planning
