Polyacrylamide effect on furrow erosion and infiltration
Application of 0.7 kg/ha/irrigation of polyacrylamide in irrigation water has reduced furrow erosion by 85 to 99%. In the present work, sediment movement and infiltration were measured in a recirculating furrow infiltrometer with two polyacrylamide treatments. Mean erosion reduction was 70%.
In the. present work, sediment movement and infiltration were measured in a recirculating furrow infiltrometer with two. polyacrylamide treatments. Mean erosion reduction was 70%. Polyacrylamide increased mean infiltration by 30%, probably the result of reduced sediment movement and furrow surface seal formation.
Polyacrylamide Effect on Furrow Erosion and Infiltration
Mean erosion reduction was 70%. Polyacrylamide increased mean infiltration by 30%, probably the result of reduced sediment movement and furrow surface seal formation.
Mean erosion reduction was 70%. Polyacrylamide increased mean infiltration by 30%, probably the result of reduced sediment movement and furrow surface seal formation. Infiltration was inversely related to maximum sediment concentration in the flowing water for both treated and untreated furrows.
Polyacrylamide and straw residue effects on irrigation
ABSTRACT: Water-soluble anionic polyacrylamide (PAM) is a highly effective erosion deterrent in furrow irrigation, but little is known about the effect of plant residues on PAM efficacy. We
There is a paucity of data, however, on the effect of PAM applied through polytubing on infiltration, erosion, nutrient transport and crop yield for Mid-South soils.
Effect of Polyacrylamide Application on Runoff, Erosion
Effect of polyacrylamide application on runoff, erosion, and soil nutrient loss under simulated rainfall. Pedosphere. 21(5): 628–638. INTRODUCTION Soil nutrients following rainfall can be lost by sur- face runoff and/or vertical percolating water in a dis- solved form and with the eroded soil particles in an adsorbed form.
Water-soluble anionic polyacrylamide (PAM) is a highly effective erosion deterrent in furrow irrigation, but little is known about the effect of plant residues on PAM efficacy. We hypothesized that increasing plant residue in irrigation furrows may alter PAM's ability to control erosion.

Polyacrylamide effect on furrow erosion and infiltration
Mean erosion reduction was 70%. Polyacrylamide increased mean infiltration by 30%, probably the result of reduced sediment movement and furrow surface seal formation. Infiltration was inversely related to maximum sediment concentration in the flowing water for both treated and untreated furrows.
The positive effects of Polyacrylamide (PAM), which is used as a soil conditioner in furrow irrigation, on sediment transport, erosion, and infiltration have been investigated intensively in recent years. However, the effects of PAM have not been considered enough in irrigation system planning and design.
Soil Erosion as Affected by Polyacrylamide Application
The objective of this study was to determine the effect of polyacrylamide (PAM) application on soil infiltration and erosion under simulated furrow irrigation with saline water. Polyacrylamide was applied by dissolving it in irrigation water at the rates of 1.5, 7.5, and 15.0 mg L −1 or spreading it as a powder on soil surface at the rates of
