The effect of applying polyacrylamide polymer on soil crusting, seedling
emergence, infiltration and runoff rates were studied on gypsiferous soils
collected from the Euphrate Basin in Syria The boxes were exposed to the
rainfall 45.48 mm/h using
a rainfall simulator. Total runoff and infiltration
measurements for all boxes were recorded. The boxes were then transferred to
a temperature-controlled room (25±2 °C) for drying. Soil moisture content and
crust strength were measured periodically until 90% water loss was recorded
in the soil. Seedling emergence was also counted daily.
