In the case of the Emajogi and Ahja rivers, the water discharge station is located upstream of the water quality sampling sites (Table 1).
Two of the water quality sampling sites (in the Emajogi and Rannapungerja rivers) were located close to the river mouth, but still excluded nutrient contributions from their tributaries (the Ahja and Tagajogi rivers, respectively) located downstream from the sampling sites.

Soils of the Eerika and Ahja sampling areas are Stagnic Albeluvisols, with loamy sand topsoil and loamy subsoil (FAO, ISRIC & ISSS 1998; Kolli 2002).
The Ahja and Eerika areas are situated on reddish-brown non-calcareous moraine (2.8 m) plain with small variations in elevation.
At Ahja and Eerika the soil samples were collected from the control plots of long-term field experiments of 1964.2004.
In the above-mentioned stretch of the Ahja valley, rather homogeneous fine-grained yellowish and pinkish sandstones of the Burtnieki Formation are exposed (Kleesment & Mark-Kurik 1997).
So far the erosion-resistant hydrogoethitic concretions have been found only in the Devonian outcrops located in the middle course of the Ahja River.
