Water Retention Crystals - The Garden Superstore
The Crystals are made up of super absorbent anionic polyacrylamide polymers that are crossed-linked and insoluble in water. However, they have the ability to absorb up to 500 times their weight in water with 95% of this water and nutrient being readily released again for the plant to take up as needed.

Water Crystals: Easy Ticket to a Green Thumb
While considered nontoxic when intact, there are some concerns that polyacrylamide water crystals mixed into soil may contaminate food plants with acrylamide, a known neurotoxin. However, commercial polyacrylamide contains tiny residual amounts of acrylamide, usually less than 0.05%.

Get PriceIs polyacrylamide a good soil conditioner?
However, as these solutions are proposed, numerous doubts and opposing opinions are emerging. Polyacrylamide (PAM), also known as “soil conditioner”, “soil amendment” and “soil stabilizer” in soil science (Gilda Dell'Ambrogio and Wong, 2019), is commonly used to modify the unfavorable and damaged characteristics of soil.
Does polyacrylamide add to soil?

Can biochar and polyacrylamide improve saline soil quality?
Hence, it is essential to choose suitable and efficient approaches to revitalize coastal saline soil quality and improve agricultural productivity. Biochar and polyacrylamide (PAM) have been widely applied as soil amendments to enhance soil structure, but the interactive effects of biochar and PAM on rice growth are unclear.
How dangerous is polyacrylamide (PAM)?
4.1.1. Polyacrylamide (PAM) As PAM is extensively used in our daily lives, it is essential to be aware of its potential hazards. Studies have indicated that PAM exhibits low or non-toxicity to humans, primarily due to the large sizes of polymers, which restrict their ability to penetrate the skin.
What is polyacrylamide (PAM)?
Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.
What is a polyacrylamide & oligomer?
Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.
