Water-absorbing polymers are long chains of molecules designed to hold large amounts of water. Water-absorbing polymers have the ability to retain up to 40 times their weight in water. While they have shown to be effective in some situations, not all situations are appropriate for water-absorbing polymers.

Water-absorbing polymers may be useful in soils with low organic
