Effect of straw and polyacrylamide on the stability
Effective management by adding straw and polyacrylamide (PAM), i.e., SPAM, to soil may increase soil stability, including structure and fertility. Thus, it is important to explore the effects of SPAM on L/WE soil, as well as to determine the appropriate ratio of straw and PAM to achieve optimal increases.
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.

Results showed that the most efficient treatment with respect to mean weight diameter of soil aggregates in dry and wet sieving (MWDdry and MWDwet), aggregate stability index (AS) and aggregate destruction index (DI) was treatment of B (150 g·m–2 wheat straw mulch and 3 g·m–2 Polyacrylamide tackifier) with 34%, 68% and 47% increment in MWDdry, MWDwet and AS, respectively as well as 37% reduction in DI as compared to the bare soil control.
Soil Science Society of America Journal Abstract - Effect
Anionic polyacrylamide (PAM) may be economical as a soil conditioner (SC) if it can stabilize structure at low application rates. Information addressing the influence of PAM on stability with low application rates and comparing improvements in stability measured under moist and air-dry conditions is lacking.
The stability mechanism and thermal properties of the system alumina–anionic polyacrylamide (PAM) was studied. The polymer’s adsorption properties in dependence on the following parameters solution pH (in the range 3–9), temperature (in the range 15–35 °C), and carboxyl groups’ content in the PAM chains (in the range 5–30 %) were examined.

A small, plastic straw – It’s something that comes with most beverages that we order, from soft drinks to even a glass of water. Though at first this small straw may not seem like a lot, when its usage is added up, plastic straws create a big problem for the environment.
POLYACRYLAMIDE EFFECT ON FURROW EROSION AND INFILTRATION
stability and flocculates suspended sediments, thereby reducing sediment detachment and transport in irrigation furrows. 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
Soil from the Loess Plateau of China is typically low in organic carbon and generally has poor aggregate stability. Application of organic amendments to these soils could help to increase and sustain soil organic matter levels and thus to enhance soil aggregate stability. A field experiment was carried out to evaluate the effect of the application of wheat straw and wheat straw-derived biochar
Polyacrylamide and Rill Flow Rate Effects - SpringerLink
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
Post-fire hillslope stabilization treatments aim to reduce runoff-erosion risks following forest fires by counteracting the impact of fire on key soil and hillslope properties. Here we evaluate the effectiveness of wood shred mulch, long-leaved pine needle mulch, and polyacrylamide (PAM) in reducing post-fire runoff and erosion in two volcanic soil types of contrasting wettability using
- Is polyaluminum chloride a coagulant?
- Inorganic coagulants such as polyaluminum chloride (PAC) have been used for years to treat water and wastewater. However, PAC as a coagulant can harm the living environment as it is toxic to humans and aquatic ecosystems. The use of natural and biocompatible materials such as sodium alginate as coagulant-aid can reduce the use of PAC.
- Does pH affect the performance of polyaluminum chloride (PAC)?
- The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
- Can polyaluminium chloride improve coagulation process in conventional water treatment?
- The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.
- Is PAC a coagulant or a dewatering agent?
- With improvement and upgrade of technologies and processes in drinking water treatment, more and more water treatment plants use polyaluminium chloride (PAC) as a coagulant in coagulation and sedimentation units and anionic polyacrylamide (APAM) as a dewatering agent in sludge handling units (Duan et al., 2025 ).
