Na osnovi pedoloških istraživanja može se zaključiti
kako je tlo na zakorovljenim plohama biološki
aktivnije, što dovodi i do brže degradacije ulja, osobito
ako ga ima u višim koncentracijama. Veće ostatke ulja
u rasadniku “Šumski vrt” može se povezati s težom


teksturom, dakle slabijom aeracijom te učestalijim
organomineralnim vezama, ali i većim izvornim sadržajem
organske tvari. Rizosfera korovskih vrsta gusto
prožima tlo i potiče mikrobiološku aktivnost, koja se
odražava na trošenje energije iz ugljikovodika.

SUMMARY: The purpose of this study is to research the effects of different
concentrations of mineral and biodegradable lubricants for chainsaws upon
seedling growth and the initial growth of pedunculate oak (Quercus robur L.),


f pthe most significant forest tree species i
iin
nn the region of the lowland Croatia.
Tests were carried out in two nurseries upon 1-m2-plots (altogether 28 test
plots and two control ones) by spilling biodegradable oil and mineral oil,
each in three concentrations (0.1 l/m2, 0.2 l/m2, 0.5 l/m2). The analysis showed
that the increased concentration of mineral oil may decrease seedling
germination; on the contrary, the bio-decomposable oil can increase it. Based
on pedological research, we may conclude that the soil of weedy plots is biologically
more active, which results in faster oil degradation.
