- The objective of this study was to evaluate the immediate and subsequent effect of AgroAquaGel 420 polymer applied in doses of 1 and 2 g kg⁻¹ on aggregate-size distribution and aggregate water stability of Haplic Luvisol developed from loess of severely erosion class. The results showed that gel-forming polymer significantly decreased the content of clods above 10 mm in diameter, and significantly increased the content of air-dry aggregates of 0.25-10 mm in surface layer of eroded soil. Application of hydrogel significantly increased the content of water-stable aggregates of 0.25- 10 mm in treated soil as compared with soil of the control. In the second year after application of hydrogel significantly larger content of water-stable aggregates of 0.25-10 mm was found in treated soil. Most effective dose of AgroAquaGel 420 was 2 g kg⁻¹.
