Comparison of glyphosate and Roundup preparations influence on inorganic pyrophosphatase activity and available phosphorus content in sandy loam
Summary.

The aim of the study was to compare the effect of glyphosate and its formulations: Roundup 360 SL (containing isopropylamine salt of glyphosate and polyethoxylated tallow amine) and Roundup TransEnergy 450 SL (containing potassium salt of glyphosate and polyethoxylated ether amine) on inorganic pyrophosphatase activity and available phosphorus content in soil. The experiment was carried out on loamy sand with organic carbon content 10.9 g·kg-1. Glyphosate and its salts amounts added to soil were: 0 (control), 1, 10, 100 mg·kg-1. Samples were adjusted to 60% maximum water capacity and they were incubated in temperature 20°C. Inorganic pyrophosphatase and available phosphorus content were measured on days 1, 7, 14, 28 and 56. The obtained results show that the observed effect of glyphosate and its formulations depended on the dosage and day of experiment. The largest changes of the measured parameters were observed after application of Roundup 360 SL – formulation containing glyphosate isopro­pylamine salt and polyethoxylated tallow amine. The positive statistically significant correlation between inorganic pyrophosphatase activity and available phosphorus content was reported only in soil treated with Roundup 360 SL.

Key words: soil, glyphosate, inorganic pyrophosphatase, phosphorus, Roundup
