摘要：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%.
