Soil Biology: Soil Animals and Soil Acidityo the release of plant nutrients, but there is a need for more exact quantitative knowledge in this field (e.g., Anderson et al. 1983; Seastedt 1984; H?gvar 1988; Abrahamsen 1990; Set?l? and Huhta 1990, 1991; Set?l? et al. 1990; Huhta et al. 1991).

Trees: Growthcientific approach when the effects of certain factors on forests (e.g. acid rain) are to be studied. Such experiments are especially valuable when it is important to study the effects under natural conditions in which the forest is influenced by a number of other environmental factors.
