Abstract
Short-time effects of the herbicide nicosulfuron on the biochemical activity of soil were investigated. Nicosulfuron rates of 0.3, 1.5 and 3.0 mg kg-1 of soil were laboratory-tested on Chernozem soil. The change in the dehydrogenase activity, in microbial biomass carbon, soil respiration and the metabolic coefficient (qCO2 ) were examined. Samples were collected for the analysis 1, 7, 14, 21, 30 and 60 days after nicosulfuron application. The obtained results indicated that the effect of nicosulfuron on the soil biochemical activity depended on its application rate and duration of activity, and the effect was either stimulating or inhibiting. However, the changes detected were found to be transient and, therefore, there is no real risk of the compound disrupting the balance of biochemical processes in Chernozem soil.
U radu je ispitivano kratkoročno delovanje herbicida nikosulfuron na biohemijsku aktivnost zemljišta. Ogled je postavljen u laboratorijskim uslovima na zemljištu tipa glinovita ilovača. Nikosulfuron je primenjen u količinama od 0,3, 1,5 i 3,0 mg kg-1 zemljišta. Praćeni su sledeći biohemijski parametri: aktivnost enzima dehidrogenaze, promene mikrobiološke biomase ugljenika, respiracija (disanje) zemljišta kao i metabolitički koeficijent (qCO2). Uzorci za analize uzimani su 1, 7, 14, 21, 30 i 60 dana posle primene nikosulfurona. Dobijeni rezultati su pokazali da je uticaj nikosulfurona na biohemijsku aktivnost zemljišta zavisio od primenjene količine i dužine delovanja, te je u zavisnosti od toga, bilo stimulativno ili inhibitorno. Međutim, utvrđene promene su bile prolaznog karaktera, tako da može da se smatra da nema realnog rizika od narušavanja ravnoteže biohemijskih procesa u zemljištu pod uticajem ovog jedinjenja.
