Opis:: The aim of study was to determine the influence of NaCl and glyphosate-based herbicide Avans Premium 360 SL on acid and alkaline phosphomonoesterase activities in sandy loam. The experiment was carried out in laboratory conditions on sandy loam with Corg content 10.90 g/kg. Soil was divided into half kilogram samples and adjusted to 60% of maximum water holding capacity. In the experiment dependent variables were: I – dosages of Avans Premium 360 SL (0, a recommended field dosage – FD, a tenfold higher dosage – 10 FD and hundredfold higher dosage – 100 FD), II – amount of NaCl (0, 3% and 6%), III – day of experiment (1, 7, 14, 28 and 56). On days of experiment the activity of alkaline and acid phosphomonoesterase activity was assayed spectrophotometrically. The obtained result showed that the application of Avans Premium 360 SL decreased in acid and alkaline phosphomonoesterase activity in clay soil. Significant interaction effect between the dosage of Avans Premium 360 SL, NaCl amount and day of experiment was reported in the experiment. The inhibitory effect of Avans Premium 360 SL was the highest in soil with NaCl at the amount of 6%.

Opis:: The aim of this study was to determine the effect of three different ionic liquids (ILs): 1-butyl-1-methylpyrrolidynium hexafluorophosphate [Pyrrol][PF6], 1-butyl-1-methylpiperydynium hexafluorophosphate [Piper][PF6] and 1-butyl-4-methylopirydynium hexafluorophosphate [Piryd][PF6] on phosphatase activities in soil. The pot experiment was carried out on loamy sand (Corg content 9.0 g/kg) with spring barley as a tested plant. The ILs was used at the dosages of 0, 1, 10, 50, 100, 400, 700 and 1000 mg/kg dry matter (DM). On day 14, soil samples were collected and activities of alkaline phosphomonoesterase, acid phosphomonoesterase, phosphotriesterase and inorganic pyrophosphatase were determined. Based on the analysis of the effect measure η2 by variance analysis – ANOVA – the percentage shares of all variable factors affecting the activity of phosphatases were also defined. Obtained results showed that the application of different dosages of all ILs caused mainly non-significant changes in phosphatase activity. Changes in activity of phosphatases were often not dependent on IL dosages. The most sensitive for ILs were both phosphomonoesterases. The type of ILs had the highest percentage participation in formation of acid phosphomonoesterase activity, while dosages of ILs affected mainly alkaline phosphomonoesterase and phosphotriesterase activities.

Opis:: Fluoride is regarded as one of the strongest oxidants, which causes oxidative changes in cells of living organisms. It may both increase the content of reactive oxygen species and inhibit the activity of antioxidative enzyme. In recent years, many researchers successfully used the properties of clay minerals in the sorption of fluoride ion from water. This raises the question of the possibility of limiting the effect of fluorine on the negative changes in plants by adding bentonite to soil. A two-year pot experiment was carried out in the Greenhouse of West Pomeranian University of Technology in Szczecin, on loamy sand and sandy loam. Each sample of soil was mixed with three different concentrations of bentonite – 1, 5, 10% of dry weight (DW) of the soil and then treated with 30 mmol of F- per 1 kg of dry weight of the soil in a form of NaF solution. A control series was prepared for each soil, to which no additives were added. The medium prepared in such way was transferred to plastic pots (3 kg each) and seeded with 16 pea seeds of Pisum sativum. In three phases of pea development (4 leaves unfolded, flowering and development of fruit), fresh leaf samples were collected and the concentrations of ascorbic acid, reduced glutathione, total flavonoids and total polyphenols were measured. Sodium fluoride introduced to the soil changed the level of antioxidant parameters in the plant, which may suggest that fluoride is involved in the formation of reactive oxygen species, resulting in oxidative stress. Bentonite in a dosage of 10% reduced the toxic effects of fluoride on the oxidative balance and morphological changes in the plant, which was observed especially for loamy sand, naturally poor in clay minerals.

Opis:: This paper assesses the dissipation of napropamide and its impact on the activity of dehydrogenases, alkaline phosphatase, acid phosphatase, and urease in sandy clay loam. The experiment was carried out on soil samples with organic carbon content of 12.08 g·kg^{-1^{, total nitrogen content of 0.97 g·kg^-1, and pH 5.24 with the following variable factors: (a) dose of Devrinol 450 SC formation (containing 450 g of naprop-amide in dm³): 0 (control), 0.5, 1, 2, 4, 8, and 16-fold hold of field dose; (b) day of experiment: 1, 7, 14, 28, 56, and 112. The half-life of napropamide ranged from 33.50 to 71.42 days. The use of napropamide at the dose recommended by the manufacturer and at the dose reduced by half appeared to exhibit low toxicity in relation to enzymes determined. In contrast, the application of elevated napropamide doses decreased the values of biochemical parameters of the soil in most cases. The Pearson’s correlation coefficients showed statistically significant negative correlation between the content of napropamide residues and the enzymatic activity of the soil.}}

Opis:: The aim of the study was to determine fluoride content in sand from sandboxes in Police town (West Pomerania, Poland). This area is exposed to excessive emissions of fluoride compounds because of the proximity of chemical plants. The sand samples were collected five times in a period from March to November in 2016. Fluoride content was determined using the potentiometric method with an ion-selective fluoride electrode. The obtained results showed that fluoride content was ranged from 0.09 to 1.48 mg·kg-1 dm. The lowest fluoride content was recorded in the sand collected in place, which was the closest to the emitter, and the largest in the samples from sandbox, which was furthest from the emitter. Analyzing the changes in the content of this element over time, the largest fluoride concentration of sand occurred in July or September depending on location. Pearson correlation coefficient at p < 0.05 (r = 0.925) showed a significant positive correlation between fluoride content and the distance from fluoride emitter.

Opis:: The aim of the study was to determine the effect of spinosad on soil biochemical and microbiological properties. The experiment was carried out on sandy loam with Corg content 10.91 g·kg^-l. Spinosad, as Spintor 240 SC was added into soil in dosages: a recommended field dosage, and fivefold, tenfold, and twenty-fivefold higher dosages. The amount of spinosad introduced into soil was between 12.55 and 313.75 g·kg^-l. Moreover, soil samples without spinosad supplement were prepared as a reference. Respective Spintor 240 SC doses were converted into 1 kg soil, taking into account 10 cm depth. After application of insecticide water emulsions, soil moisture was brought to 60% maximum holding water capacity. The soil was thoroughly mixed and stored in tightly-closed polyethylene bags at 20 °C for a period 4 weeks. During the ex-periment dissipation of spinosad, soil enzymes (dehydrogenase, alkaline phosphatase, acid phosphatase, urease) and number of bacteria, fungi, actinomycetes were assayed. Obtained results showed, that dissipation of spinosad in soil was relatively fast – the DT50 of this insecticide was ranged between 1.11 and 2.21 days. Spinosad residues had different effects on soil microbiological and biochemical properties. However, over time the impact of this insecticide definitely decreased. This indicated that the use of spinosad in organic farming, particularly in the field dosage, does not pose a long-term threat to the soil environment.
