Incorporation of radioactive precursors - the suitable method for measurement of anabolic activity of soil bacteria
Uhlířová, Eva
The procedure of the thymidine and leucine incorporation technique and its using for direct determination of bacterial anabolic activity in soil are described. Advantages and disadvantages of the method are discussed and possibilities of the method application on the field of environmental studies are given. The paper is completed with results of the bacterial growth rate measurement using the method of thymidine incorporation.
Productivity of differently managed mountain meadows
Mašková, Z. ; Květ, Jan ; Zelený, D.
A mountain meadow (about 1160 asl) situated in the Šumava NP/BR was subjected to 3 treatments applied in mid-July in 4 succesive years: (i)mowing, (ii)mulching, (iii)no management. Seasonal courses of aboveground biomass varied between 0,35-0,5 kg.m-2 in all treatments and years while belowground biomass did between 6-9 kg.m-2. R/S ratio varied between 6-18, being mostly highest in the mown treatment. Litter dry weight varied mostly between 0,2-0,8 kg.m-2, being usually hightest in the unmanaged treatment. Seasonal courses of the above 3 production characteristics were highly variable. Estimated average annual aboveground net production was 0,6-0,7 kg.m-2 for all treatments and years.
