Division II.6 Analysis methods
United Kingdom
The inventory of the forest soil solution monitoring distinguishes between mandatory and optional parameters (See list below).
LIST OF PARAMETERS
| Measurement is advisable when acid base budgets are calculated. | ||
| Measurement of NH4 is advised in areas with high NHx deposition (above 20 kg NHx per ha per year). | ||
| Advised since these are minor nutrients. Member States are free to analyse more, all, or part of the optional parameters. | ||
| Man. = Mandatory Opt. = Optional | ||
