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.

Effect of polyacrylamide applications on soil hydraulic characteristics and sediment yield of sloping land. In Q. Zhou (Ed.), 2011 2nd International Conference on Challenges in Environmental Science and Computer Engineering (Vol. 11, pp. 763–773, Procedia Environmental Sciences).
The effect of polyacrylamide (PAM)on the eluviations of NH4+ and NO3-in purple soil was studied by the intermittent leaching experiment.The results showed that the effects of PAM was strikingly to transfer and eluviate of nitrogen. The low dosage (0.01%-0.05%
Effects of polyacrylamides with different hydrolysis degrees
A simulation experiment was carried out to identify the optimal polyacrylamide(PAM)formulations (hydrolyis degree,HD;molecular weight,MW)for increasing the water holding capacity of sandy yellow soil distributing widely in Chongqing City.The results indicated that

Polyacrylamide molecular formulation effects on erosion
Yang, L.-x., Li, S.-c., Sun, H.-l., Ye, F.-f., Liu, W. and Luo, S. 2011. Polyacrylamide molecular formulation effects on erosion control of disturbed soil on steep rocky slopes. Can. J. Soil Sci. 91: 917-924. Soil erosion caused by increasing runoff and soil disturbances is a severe problem on steep rocky slopes. One possible soil erosion control measure is the application of polyacrylamide
A field experiment was carried out to evaluate the effect of the application of wheat straw and wheat straw-derived biochar (pyrolyzed at 350-550 °C) amendments on soil aggregate stability, soil organic carbon (SOC), and enzyme activities in a representative Chinese Loess soil during summer maize and winter wheat growing season from 2013 to 2015.
Application of polyacrylamide reducing nitrate-N
Application of polyacrylamide reducing nitrate-N and soluble P losses from a Lou soil in a soil column experiment: Yuan Xuefeng1,2,3, Jian Jinshi4, Wei Xindong1,3, and Ying Yue1: 1. School of Earth Science and Resources, Chang’an University, Xi’an 710054, China; 2.
Straw mulch and organic matter input can notably decrease unit sediment yields caused by runoff and thus reduce soil erodibility. The contribution of organic matter treatment (OM), straw mulch treatment(SW) and organic matter+straw mulch(OM+SW) treatment on the reduction to soil erodibility were on average 22.30%, 29.76% and 35.04%, separately.
- What is poly Aluminium chloride (PAC)?
- In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.
- What is poly aluminum chloride (PAC) in water treatment?
- In the realm of water treatment, various chemicals play a crucial role in ensuring the provision of clean and safe water. One such chemical is Poly Aluminum Chloride, commonly known as PAC. In this blog post, we will introduce what PAC is, its properties, applications, and its significance in water treatment processes.
- What is poly Aluminium chloride?
- This article delves into the chemical properties, uses, and safety considerations of poly aluminium chloride, while also examining its pivotal role in the water treatment industry. Poly aluminium chloride, commonly abbreviated as PAC, is a complex chemical compound used primarily as a coagulant in water purification.
- Why is poly Aluminium chloride used in water treatment?
- The primary use of poly aluminium chloride in the water treatment process is to remove impurities and clarify water. This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed.
