| Description
| - We proposed a new method to determine the rate constant of biochemical oxidation of soil organic matters that makes it possible to evaluate their stability by Spektroquant Merck BOD photometric tests. If smaller samplings are used and individual determinations are performed, it can replace BOD vacuum measuring by an Oxi Top Control Mercks system. The time and labour consumption of this vaccum method is sometimes criticised, but it has demonstrable work advantages for a large series and so it is still recommended. The two methods are identical as for the correctnes and coincidence of results and they do not differ by either lower or higher results and therefore we recommend the new method with photometric tests for smaller series of samples. For the high time and labour consumption we must warn against the use of traditional BOD dilution method with volumetric determination of oxygen for the determination of rate constans.

- Byla navržena nová metoda stanovení rychlostní konstanty biochemické oxidace půdních organických látek, kterou lze hodnotit míru jejich stability, pomocí fotometrických testů Spectoquant Merc BOD, jež mohou při menších výběrech vzorků a při jednotlivých stanoveních nahradit podtlakovou metodu měření BOD systémem Oxi Top Kontrol Merc. Tato podtlaková metoda je někdy kritizována pro náročnost a složitost, ale pro velké série vzorků má prokazatelné pracovní přednosti. Obě dvě metody jsou vhodné z hlediska správnosti a shodnosti výsledků a neliší se nižšími ani vyššími výslednými hodnotami, a proto doporučujeme novou metodu práce s fotometrickými testy pro menší série vzorků. Z časových a pracovních důvodů lze jen varovat před použitím klasické BOD zřeďovací metody s volumetrickým stanovením kyslíku k měření rychlostních konstant. (cs)
