Impact of jet-fuel on chemical properties of diverse soils

In the SE Smolensk-Moscow upland and in the Baikonur cosmodrome, changes in the chemical properties of diverse soils (Dystric Arenosols, Cambic Calcisols, Fibric Histosols and Albic Luvisols) were studied after the jet-fuel treatments of 1, 5, 10, 25 and 100 g/kg during a one- year pot experiment (one soil per region) and during two-year field experiments (in all soils). Among the controlled soil properties, only organic matter carbon content increased as jet-fuel load increased. For the other soil properties namely moisture, pH value, the concentration of available phosphorus and potassium, exchangeable ammonium, water-soluble nitrate, the total content of carbon and nitrogen, there were no obvious trends, which reflects a rather high stability of these soil properties to jet-fuel contamination in loads up to 100 g/kg.
