Using Polyacrylamide (PAM) to Reduce Erosion
One approach to reducing this type of erosion is to use chemical treatments to augment seeding and mulching. The chemical polyacrylamide (PAM) is well suited for erosion control enhancement, and its use is described below.

Application of polyacrylamide to reduce phosphorus losses
Use of anionic polyacrylamide (PAM) to control phosphorus (P) losses from a Chinese purple soil was studied in both a laboratory soil column experiment and a field plot experiment on a steep slope (27%). Treatments in the column study were a control, and PAM mixed uniformly into the soil at rates of 0.02, 0.05, 0.08, 0.10, and 0.20%.
Polyacrylamide (PAM), which is a hydrophilic polymer, has been used in the field of agriculture for nearly half a century due to its ability to increase infiltration and decrease irrigation
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.
Toxicity of Anionic Polyacrylamide Formulations when Used for Erosion Control in Agriculture. TECHNICAL REPORTS. 238. Addition of anionic polyacrylamide (PAM) to agricultural. irrigation water can dramatically reduce erosion of soils. However, the toxicity of PAM to aquatic life, while often.
Control of Rainfall-Induced Soil Erosion with Various
Several types of organic polymers with various molecular weights and surface charges are produced for various industrial and agricultural purposes, and recent studies have shown that high molecular weight anionic polymers are the most effective in reducing runoff and soil loss. However, anionic polyacrylamide (PAM) is marketed under various commercial names with variable molecular weight and length according to its chemistry (Barvenik 1994).
Splash erosion is recognized as the first stage in soil erosion process and results from the bombing of the soil surface by rain drops. One of the soil erosion control methods is the use of chemical polymers. The purpose of this study was to investigate the effects of different rates of polyacrylamide - PAM (0, 2, 4 and 6 kg/ha) - on the rate of splash erosion at three rainfall intensities (60
Using polyacrylamide to control soil splash erosion
[ USING POLYACRYLAMIDE TO CONTROL SOIL SPLASH EROSION IN RAINFALLS WITH VARIABLE INTENSITY AND DURATION ] the patch application of polyacrylamide (PAM) with an additional erosion control practice. They found that PAM could be an excellent practice to control soil erosion. Sepaskhah and Shahabizad (2010) also measured the effects of water
Use of anionic polyacrylamide (PAM) to control phosphorus (P) losses from a Chinese purple soil was studied in both a laboratory soil column experiment and a field plot experiment on a steep slope (27%).

Polyacrylamide and Rill Flow Rate Effects on Erosion
Overland flow caused by rainfall is one of the critical factors influencing soil erosion and loss of soil nutrients. Therefore, the study on the mechanism and controlling measures of soil nutrient transport proposed is considered important. A simulation experiment was performed to investigate the effects of polyacrylamide application rates (0, 1, 2, 4, and 8 g/m2) and flow rates (400 ml/min
Global change affects biogeochemical cycles, and soils play a key role in these cycles [1,2].Soil erosion is a threat to soil sustainability and scientific research is looking for new solutions to reduce and control the accelerated soil erosion rates in agricultural lands [3,4].Soil erosion is a worldwide problem that needs solutions to achieve sustainable production of fibers and food for
- What is polyaluminium chloride production?
- PolyAluminium Chloride production is one of the most exigent process for glass-lined equipement due to its high corrosive and abrasive effect. That's why, the experience and the qualification of De Dietrich Process Systems allow to meet qualitatively those process requirements.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
- Is polyaluminum chloride a Lewis acid catalyst?
- Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst in inte
- Is polyaluminum chloride used in water treatment?
- Polyaluminum chloride (PAC) can be synthesized and used in water treatment as investigated in this study using a colorimetric speciation method. Stable preparations of PAC solutions can be produced where a relatively stable cationic polymer predominates.
