Experimental approach for studying interrelationships between macroarthropods, soil biota, decomposion rate of litter and organic matter accumulation in soil

Kajak A.

Polish Journal of Ecology

2000

Vol. 48, nr 4

263-269

The paper presents experimental design applied to analyse the role of macroarthropods patrolling soil surface on decomposition rate of grass litter (Dactylis glomerata). In the experiment density of micro- and mesofauna and microbial abundance in mesocosms accessible (open - O) and not accessible (closed - C) for large arthropods was compared. Mass loss of litter, mineralization rate of carbon and nitrogen, humus acid storage in sandy substratum underlying litter was estimated also. Results are presented in several papers. Effect of exclosures on the intensity of surface patrolling by macroarthropods and on their density in mesocosms in also presented.
