Reducing Furrow Irrigation Erosion with Polyacrylamide
Furrow irrigation‐induced erosion is nearly halted by small additions of water‐soluble polyacrylamide (PAM) to irrigation water. PAM is an environmentally safe flocculent used extensively in municipal water treatment, paper manufacturing, food processing, and other sensitive applications.
ABSTRACT. Furrow-irrigation induced soil erosion threatens sustainable irrigated agriculture worldwide. Small concentrations of a moderate-charge-density anionic polyacrylamide (PAM), dissolved in irrigation water has been used to nearly eliminate soil loss from irrigated furrows and has increased net infiltration (total inflow minus total outflow).
Erosion Control in Furrow Irrigation Using Polyacrylamide
Adding dilute quantities of moderate-charge-density anionic polyacrylamide (PAM) to furrow irrigation water can greatly reduce runoff soil losses and, in some cases, increase net infiltration.
Furrow irrigation-induced erosion is nearly eliminated by small additions of water-soluble polyacrylamide (PAM) to irrigation water. PAM is an environmentally safe industrial flocculent widely used in municipal water treatment, paper manufacturing, food processing and other sensitive applications.
PAM in Furrow Irrigation, an Erosion Control Breakthrough
Furrow irrigation-induced erosion is nearly eliminated by small additions of water-soluble polyacrylamide (PAM) to irrigation water. PAM is an environmentally safe industrial flocculent widely used in municipal water treatment, paper manufacturing, food processing and other sensitive applications.
Furrow irrigation . can be a major contributor to soil . loss. Reducing soil erosion on vulnerable acres can help maintain topsoil for future generations. Furrow irrigation results in greater loss because, unlike a center pivot system, furrow irrigation uses soil as the transmission line, distrib - uting water along the irrigation furrow.

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 hypothesized that increasing plant residue in irrigation furrows may alter PAM's ability to control erosion.
If inexpensive, effective, easy erosion control were available, many furrow irrigation farmers could improve resource conservation and water management. Literature Summary. Small amounts of a specific class of polyacrylamide (PAM) copolymer can virtually halt furrow irrigation‐induced erosion.
Reducing furrow irrigation erosion with polyacrylamide (1997)
If inexpensive, effective, easy erosion control were available, many furrow irrigation farmers could improve resource conservation and water management. Small amounts of a specific class of polyacrylamide (PAM) copolymer can vir-tually halt furrow irrigation-induced erosion.
It also has being extensively used in furrow irrigation for soil erosion control and increased infiltration (Lentz et al., 1992, Lentz and Sojka, 1994, Sojka et al., 1998a, Sojka et al., 1998b). Polyacrylamide is a stable compound and considered to be environmentally safe for use as a soil conditioner ( Bologna et al., 1999 , Seybold, 1994 ).

- How many types of polyaluminium chloride are there?
- There are four types of polyaluminium chloride for sale for water treatment, specifically PAC 30% 01&02. The other types, PAC 30% 03 and PAC 28% 04, are used for industrial wastewater treatment. The four types can be easily distinguished by color, from white to light-yellow and deep-yellow.
- What is the price trend of polyaluminum chloride?
- According to Procurement Resource, the price trend of Polyaluminium Chloride is estimated to trace a southwards journey as its demand from the downstream sectors does not seem to follow a growing trend. Domestic mainstream quotations for industrial polyaluminum chloride were 2373.75 RMB/MT on March 29. The Chinese market had mostly stayed stable.
- What is polyaluminum chloride used for?
- Polyaluminum chloride is used in water treatment for forming dense and large alum blooms in the wastewater treatment process. The sedimentation speed is fast, and the treatment effect is obvious. In water treatment, PAC chemical also has an application in the mining industry for ore flotation, where it can act on mineral separation.
- Why is polyaluminium chloride used in aquaculture?
- Polyaluminium chloride is used in aquaculture to precipitate and remove a large amount of organic matter in the water body. It also has roles in increasing soil moisture content, inhibiting the formation of soil crusts, and increasing water infiltration.
