The Amounts of Nitrogen as Ammonia and Nitric (and Nitrous) Acid in the Rain-water Collected at Uithuizermeeden, Groningen

Abstract

For several years observations have been made on the composition of rain-water, collected by Mr H. Welt, at Uithuizermeeden, a village in the northern part of the Province of Groningen. These observations were made as a part of a research on nitrification in a light clay-soil, by the method of drainage-plots such as are well known from the Rothamsted investigations. The results of these researches appeared in a Dutch journal. In the meantime it seems desirable to publish the results relating to the composition of rain-water.
