Effectiveness of Polyacrylamide, Wood Shred Mulch, and Pine Needle Mulch as Post-Fire Hillslope Stabilization Treatments in Two Contrasting Volcanic Soils
Post-fire hillslope stabilization treatments aim to reduce runoff-erosion risks following forest fires by counteracting the impact of fire on key soil and hillslope properties. Here we evaluate the effectiveness of wood shred mulch, long-leaved pine needle mulch, and polyacrylamide (PAM) in reducing post-fire runoff and erosion in two volcanic soil types of contrasting wettability using rainfal...
متن کاملApplication of Polyacrylamide for Splash Erosion Control on Marl Soil
Splash erosion is recognized as the first stage in the process of erosion that results in bombardment of the soil's surface with rain drops. Two basic processes in soil erosion are the dispersement of soil particles by rain drops and the changes caused to the soil's structure, which are then moved by runoff. In this research,the effect of various polyacrylamide (PAM)values (0, 0.2, 0.4 and 0.6 ...
متن کاملCommercial versus synthesized polymers for soil erosion control and growth of Chinese cabbage
Soil erosion leads to environmental degradation and reduces soil productivity. The use of anionic polyacrylamide (PAM) and synthesized biopolymer (BP) using lignin, corn starch, acrylamide, and acrylic acid were tested to evaluate soil erosion, water quality, and growth of Chinese cabbage (Brassica campestris L.). Each treatment of PAM and BP was applied at 200 kg ha(-1) to loamy sand soil and ...
متن کاملPost-fire runoff and erosion from rainfall simulation: contrasting forests with shrublands and grasslands
Rainfall simulations allow for controlled comparisons of runoff and erosion among ecosystems and land cover conditions. Runoff and erosion can increase greatly following fire, yet there are few rainfall simulation studies for post-fire plots, particularly after severe fire in semiarid forest. We conducted rainfall simulations shortly after a severe fire (Cerro Grande) in ponderosa pine forest n...
متن کاملPost-fire Erosion and the Effectiveness of Emergency Rehabilitation Treatments over Time
runoff and erosion rates by one or more orders of magnitude, and these increases can threaten life and property as well as severely degrading water quality and aquatic ecosystems. Each year millions of dollars are spent on emergency postfire rehabilitation treatments to minimize flood runoff and soil erosion. Few data have been available to systematically evaluate the effectiveness of these tre...
