Impact of Technogenic Saline Soils on Some Chemical Properties and on the Activity of Selected Enzymes

The study was based on saline soils with surface mineral layers impacted by the waste produced soda plant in Poland. activity of selected enzymes (catalase CAT, alkaline AlP, and acid phosphatase AcP), pH KCl, content clay, total organic carbon (TOC), nitrogen (TN), exchangeable bases (TEB), electrical conductivity (ECe), CaCO3, concentration available phosphorus AP were investigated soil next to plant. Based enzyme activity, following calculated: enzymatic indicator AlP/AcP, resistance index (RS), resilience (RL), relative changes (RCh), time (TI). sampled from horizon spring autumn eight (S1–S8) sampling sites area control point (C). Soil is characterized reaction. Statistical analysis (ANOVA, η2 effect size) showed significant variation parameters under influence different TOC ranged 4.70 47.7 g kg−1, TN 19 4.36 kg−1. ECe between 6.87 204 mS cm−1. highest values confirmed S1 both autumn. Higher TEB noted In within impact plant, decreased S1, S3, S6, S8 (in spring), lowest recorded at 1.20, 4.14, 5.98, 0.99 mg respectively. AlP site S4. AcP decreased, as compared which seen negative coefficient (RCh). RCh catalase activities that S2, S4, S5, increased, control. (RS) for phosphatases reported S6. Research shows their indexes make it possible conduct long-term monitoring identify processes soil.
