Abstract
A soil conditioner, PAW‐1 synthesized from industrial acrylic waste, was evaluated for its effectiveness for decreasing crust strength, runoff, and soil loss, and for increasing the emergence of cotton seedlings and infiltration rate. Field experiments were conducted on loamy sand and sandy loam soils. Treatment of a sandy loam soil with the soil conditioner in the amount of 3.75 g m‐2 substantially decreased crust strength after a 15‐mm simulated rainfall and increased the final emergence number of cotton seedlings fourfold, as compared to untreated plots. The treatment of a loamy sand soil increased its final infiltration rate by 53% and decreased runoff and soil loss by 36% and 52%, respectively, during a series of seven natural rainstorms spread over 15 days.
