The guidelines in this chapter are based on literature reviews, the experimental data from chronosequences of afforested stands in Denmark, Sweden, and the Netherlands (described in Chapter 2, 3 and 4), and on the developed mechanistic metamodel (METAFORE) and the spatial Decisio

Rates of soil C sequestration ranged from being negligible in two of the Danish chronosequences to 1.3 Mg C ha. yr. for

At the oak stands leaching decreased from 35 to 20% of the precipitation in the first 30 years. In the spruce stands the water recharge varied considerable between the four investigated chronosequences but

The Eutrend model was used for the calculation of N deposition, and it calculates concentrations and depositions as a function of surface characteristics.
