Objective
There is NH3- and N02-dependent nitrogen deposition on forest canopies. Generated ions (NH4+, N02-, N03-) dissolve in the canopy throughfall and can be taken up from the soil by trees and competitive organisms. Partially they also leak into the subsoil water. Gaseous N02 and NH3 diffuse into needles via open stomata. In trees, airborne reduced or oxidized nitrogen is incorporated into organic compounds. Resultant nitrogen compounds may stimulate tree growth. Alternatively, they may accumulate. Nitrogen fluxes can be accompanied by mineral cation fluxes. Cations balance the charge of N03- or organic nitrogen-containing anions (e.g. proteins). There is also NH4+ - cation exchange at root surfaces and in the soil matrix. Field measurement of cation flux changes and integration of obtained parameters into an available canopy growth model is expected to quantify nitrogen-caused canopy thinning or cation deficiency, and the separate derivation of N02-tolerance limits for different forest ecosystems.

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
