Abstract:
On the background where no absorbent was used, the highest rate of degradation of the petroleum hydrocarbons (47%)
was attained in the variants treated with the AH-SH fertilizer, the highest rate of degradation of the hydrocarbons (45%)
on a background without absorbent was attained in the variants treated with potassium humate and microelements along
with the bacterial inoculant. Upon utilization of 16 t/ha peat as absorbent without using any microbial inoculant, the
highest rate of degradation (43%) of the petroleum hydrocarbons was attained following the fertilization with AH-SG1,
upon application of the bacterial inoculant, the highest rate of degradation of the petroleum hydrocarbons (47%) was
provided by fertilization with AH-SG2. Upon application of a 16 kg/ha dose of Zeba absorbent without any bacterial
inoculant, the highest rate of degradation (47%) of the petroleum hydrocarbons, 45 days after the application of the
treatments, was provided by the fertilizer AH-SG2. Upon treatment with 16 kg/ha Zeba absorbent and application of the
bacterial inoculant, the highest rate of degradation (52%) was provided by the fertilizer AH-SG1. The second highest
rate of degradation, 51%, was provided by the fertilizer AH-SG1. Upon application of 32 kg/ha Zeba absorbent without
any bacterial inoculant, the best results in the bioremediation process were obtained following the treatment with the
fertilizer AH-SG2 in a dose of 650 l/ha plus 64 kg/ha glucose. In these variants, the level of the petroleum hydrocarbons
dropped by 59% after just 45 days of treatment or 60 days after the pollution. Upon application of 32 kg/ha Zeba
absorbent along with the bacterial inoculant, the highest rate of degradation of the petroleum hydrocarbons (54%) was
provided by the fertilizer AH-SG1. The second highest rate – 53% – was provided by the fertilizer AH-SG2.
