F. Thamm et P. Widmoser, ABOUT THE HYDROLOGICAL ROLE OF ORGANIC LA YERS IN FOREST - METHODS AND FIRST RESULTS, Zeitschrift fur Pflanzenernahrung und Bodenkunde, 158(3), 1995, pp. 287-292
The forest floor (total organic matter above the surface of the minera
l soil) is an important interception storage for throughfall. Therefor
e, it must be considered in detailed water balances of forest. The obj
ective in this paper is to present a method for measuring the forest f
loor percolation. It was developed within the framework of the interdi
sciplinary project Ecosystem research in the Bornhoyed lake region. A
technique for permanent registration of mineral soil input and a vacuu
m control system for mini lysimeters and suction plates are described.
The registration system has a resolution about 0,1 mm. Some figures i
llustrate the instrumentation, respectively measured row data and some
results. Finally, the used materials, their properties and sources of
supply are presented.
