Seasonal changeability of soil enzyme activity has not been entirely known. The aim of the paper was presenting the seasonal changeability in enzyme activity in fresh forest sites. From 10/06/2007 to 20/06/2008 samples were taken seven times at 6-weeks' intervals from two sample plots representing sites Lśw, LMśw, BMśw and one for Bśw site. Activity of dehydrogenase, protease and urease have been marked in the soil samples. As a result of conducted research the minimum value for enzymatic activity was found in October 2007 and April 2008. Maximum values for the activity of studied enzymes were noted in January and June 2007 and 2008, while no statistically significant differences were found between enzymatic activity marked in June 2007 and June 2008.

Sezonowa zmienność aktywności enzymów glebowych nie jest poznana do końca. Celem pracy było przedstawienie sezonowej zmienności aktywności enzymatycznej na świeżych siedliskach leśnych. Od 10.06.2007 roku do 20.06.2008 roku zostały pobrane próbki siedmiokrotnie, w odstępach 6-tygodniowych, z dwóch powierzchni reprezentujących siedliska Lśw, LMśw, BMśw i jednej - siedliska Bśw. W próbkach gleby oznaczono aktywność dehydrogenaz, proteaz i ureazy. W wyniku przeprowadzonych badań stwierdzono minimum wartości aktywności enzymatycznej w październiku 2007 i kwietniu 2008 roku. Maksymalne wartości aktywności badanych enzymów zanotowano w styczniu i czerwcu 2007 i 2008 roku, nie stwierdzono statystycznie istotnych różnic pomiędzy aktywnością enzymatyczną oznaczoną w czerwcu 2007 roku i w czerwcu 2008 roku.
