对沿着断面（30 m）测得的桑迪土壤地下水位溶质浓度进行了统计分析，以分离和量化确定性和随机变异性成分。耕地下硝酸盐浓度和针叶林下硫酸盐浓度的结果。这些溶质浓度在地下水位的空间变异性的影响，确定性的变异组件。这些组成部分代表了以下外在因素：施肥的做法，耕地和针叶林下，输入到土壤中通过穿透的冠层沉积的大气成分。
Solute concentrations at the groundwater table in sandy soils measured along transects (30 m) were statistically analyzed to separate and quantify deterministic and stochastic variability components. Results for nitrate concentration under arable land and for sulfate concentration under coniferous forest are presented. Spatial variability of these solute concentrations at the groundwater table is influenced by deterministic variability components. These components represent the following extrinsic factors: Fertilization practices on arable land and, under coniferous forest, input into the soil via throughfall of canopy-deposited atmospheric constituents.
