Measurement of aquatic humus content by spectroscopic analyses

Water Research, 2000
Abstract To develop a specified method to estimate humus contents in natural fresh waters, the colour of humic water samples was measured for fractionated and original water samples by spectrophotometry. The results were compared to those of the comparator method and they support the use of 400 or 465 nm.

Enzymic Activity and Humus Content in Eastern Siberian Soils

Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1973
Summary The enzymic activity in the soil is controlled by many factors, including the organic matter content in the soil. The report contains data on the interrelations of enzymic activity in the soil and humus content. The nature of this relationship is discussed with reference to redoxases and hydrolases of the soil.
