abstract:
Immediate and consequent effect of Teracryl polymer in two doses (1 and 2 g kg-1) on soil aggregation and aggregate water stability of Haplic Luvisol developed from loess, subjected to surface water erosion, was investigated in a plot experiment. The results obtained prove that Teracryl significantly decreased the content of unfavourable clods >10 mm in diameter and increased the content of air-dry aggregates of 1-5 mm and 0.25-1 mm and the content of water-stable aggregates of 1-10 mm in the surface layer (0-5 cm) of eroded soil. In the second year after the application of Teracryl in the soil there was a significant increase of the content of water-stable aggregates of 0.25-10 mm as compared with the soil of the control plots. The most effective application of the polymer was in the dose of 2 g kg-1.
