Impact of oil contamination of grey forest soil on its nutrient status and plant safety

Open Access

Table 1.

Effect of oil pollution^* on the content of labile forms of nitrogen, phosphorus and potassium in 0–30 cm layer of grey forest soil

Soil	Alkali‐hydrolyzable nitrogen according to Kornfield	Labile forms according to Kirsanov
Soil	Alkali‐hydrolyzable nitrogen according to Kornfield	phosphorus	potassium
Uncontaminated (control)	158^** 100	126 100	121 100
Oil‐contaminated	102 65	98 78	97 80
LSD₀₅ (mg/kg)	10	6	6

Note: * – soil was sampled 16 days after contamination; ** – in numerator in mg/kg of soil, in denominator – in percentage relative to control.
