variavility - Opis:
- The objective of the study was to investigate variability of chemical features of upper horizons in forest soils as well as confirmation of collecting the mixed sample that is supposed to describe the soil conditions more effectively. The lowest variability (ca 10%) was observed for pH in H2O and KCl as well as C/N ratio. The highest coefficient of variance exceeded 100% (Ca content). For almost all analysed chemical parameters, the results obtained for mixed sample (average of 5 samples systematically distributed within the study area) are in ±1 standard deviation range from the average of 25 individual samples.
