… an anionic soil conditioner polymer. Topsoil loss can mean a long-term reduction in soil productivity, crop yield and the life expectancy of downstream storage reservoirs. In the short term, producers are faced with reuse pits to clean or a buildup of soil at the lower ends of fields which must be redistributed. Measures must be taken to reduce or eliminate soil erosion and sustain soil resource. Polyacrylamide (PAM) is one such measure. PAM is a long-chain synthetic polymer that acts as a strengthening agent, binding soil particles together. It is harder for water to move these larger, heavier particles of soil. USDA researchers in Kimberley, Idaho began wor
king with PAM in the early 1990s as a method to reduce erosion in furrow irrigation. Their tests indicated PAM applied in the irrigation water reduced soil erosion in furrows by over 95 percent, when compared to irrigation without the polymer.
Advantages for Anionic Polyacrylamide in Soild Stabilization:
- Improves stability of problem soils to prevent soil detachment (i.e. prevents erosion) in the first place
- Provides quick stabilization where vegetation has yet to be established
- Promotes flocculation (reduces settling time) of smallest particles
- Increases soil pore volume and permeability, thus decreasing imperious cover
- Convenient and easy to apply and store along with other soil amendments (fertilizer, mulch, etc.) with conventional seeding, mulching, or irrigation equipment
- Re-application may not be necessary for several months if treated areas are mulched
- Reduces seed, pesticide, and fertilizer (phosphorus and nitrogen) losses that hinder vegetation establishment on site, increase costs, and promote nutrient and chemical loading offsite
Polyacrylamide used for erosion control should have a negative (anionic) molecular charge. Research conducted in Idaho showed that less than 5 percent of PAM applied during an irrigation left fields in the runoff water. This research also showed that after leaving the field, the PAM concentration in the runoff quickly fell below detectable limits (<1,500 yards). There is no indication of any adverse impact on soil, plant or aquatic systems when anionic PAM is used to control soil erosion. Because PAM limits soil erosion, using it can prevent nonpoint source pollutants from leaving the field. Nonpoint source pollutants include the soil and contaminants that can be attached to the soil — nutrients, herbicides and pesticides.
