Effect of silver on the activity of dehydrogenases in different soil types |
|
In this study, the effect of silver nitrate 1, 10, and 100 mg / kg on the activity of dehydrogenases of three types of soils in the South of Russia was evaluated. In the course of the study, it was found that silver had a negative effect on the activity of dehydrogenases in sierosands, brown forest soil and ordinary chernozem. At a silver concentration of 1 and 10 mg / kg, inhibition of the dehydrogenase activity of sierosands was noted by 16 and 39%, and in brown forest soil by 21 and 42%, relative to the control values. A silver concentration of 100 mg / kg inhibited the activity of dehydrogenases in sierosands, brown forest soil, and ordinary chernozem by 40, 58, and 56% of control, respectively. According to the degree of resistance to contamination with silver nitrate according to the activity of dehydrogenases, the studied soils form the following series: ordinary chernozem (83)> sierosands (76) ≥ brown forest soil (70)
