Soil Solution

The ECN protocol for soil solution (SS)


Protocol file


Site types that use this protocol


Soil solution chemistry is likely to be affected by physical and chemical changes in the environment and itself to have important effects on ecosytem processes; for example, soil temperature and moisture status strongly influence the microbial activity in soil which controls nutrient release into the soil solution (Swift, Heal & Anderson 1979). In turn, soil solution nutrient status has a major influence on plant productivity and thus on animal productivity.

Replicated suction lysimeters at the base of a & b soil horizons are sampled every two-weeks and analysed fo 15 chemical variables.

Our field activities


Now that autumn has arrived the ECN fieldwork calendar begins to quieten down. We cease monitoring most terrestrial invertebrates apart from spiders. In rivers and lakes we make the last freshwater invertebrate survey of the year.
