Granular and Dissolved Polyacrylamide Effects on Hydraulic
Polyacrylamide (PAM) has been demonstrated to reduce erosion under many conditions, but less is known about the effects of its application method on erosion and concentrations in the runoff water.
Surface application of dissolved polyacrylamide (PAM) mixed with gypsum was found to be effective in decreasing seal formation, runoff and erosion. Surface application of dry granular PAM mixed with gypsum was effective in decreasing runoff and erosion. However, surface application of dry granular PAM without a source of electrolytes was not
Granular and Dissolved Polyacrylamide Effects on Erosion
The effects of low concentrations of two polymers, an anionic polyacrylamide (PAM) and a cationic polysaccharide (PSD), on soil permeability and erosion from a grumusol and a loess, were studied
The impact of a linear, high molecular weight, moderate negative charge density polyacrylamide (PAM) on soil hydraulic conductivity (HC) and the mechanisms involved are partially understood. Our objectives were to evaluate the impact of (i) electrolyte concentration of the PAM solution, (ii) mode of PAM application, and (iii) drying of the
Polyacrylamide and Rill Flow Rate Effects on Erosion
A simulation experiment was performed to investigate the effects of polyacrylamide application rates (0, 1, 2, 4, and 8 g/m 2) and flow rates (400 ml/min, 600 ml/min, and 800 ml/min) on runoff, infiltration rate, soil losses, and the concentration of ammonium nitrogen (NH 4 +) in runoff at loess slope (0.8 m (width) × 1.5 m (length) and 5
A simulation experiment was conducted to investigate the effects of polyacrylamide (PAM) application rates (0, 0.5, 1, 2 and 4 g/m 2), rainfall intensities (30, 60 and 90 mm/h) and the applied positions (top, middle and bottom with application rate of 2 g/m 2) on runoff, soil and total nitrogen (TN) losses at loess slope.
Effectiveness of Granular Polyacrylamide to Reduce Soil
The objective of this work was to test the effectiveness of granular polyacrylamide (PAM) to reduce erosion in a Calcic Regosol exposed to different fire conditions. Three treatments were selected representing disturbances that coexist after a wildfire: unburned, low‐moderate severity direct fire, and prolonged heating under moderate
(20 WDG) in each Terrene™ pack, which when dissolved in 1 gallon water provides a 0.05% solution. Since this formulation is designed both for indoor and outdoor uses, it is readily picked-up by insects on a wide range of surfaces. The objectives of this research were to study the efficacy of Arilon™ by observing effects of limited exposure
