Humic lake acidification experiment. Status pr September 1990, one week before start of the treatment
(NIVA-rapport;2535, Research report, 1990)An important conclusion from the acid rain research during the late 1970's and the early 1980's, was that humic substances (HS) in the water affected the response of acid rain. HS acts as a modifier on both the chemical ... -
Interpretation of SoilData from the Rain Project
(NIVA-rapport;2294, Research report, 1989)Process-oriented models for prediction of soil and water acidification at the catchment scale require soil chemical and physical data as input parameters. Choice of soil properties characteristic for an entire catchment ... -
