Potassium polyacrylate

Potassium polyacrylate may cause severe eye irritation, and should not be released into the environment.

This improved soil readily releases moisture, along with water-soluble nutrients, to plant roots on demand.

It is composed of a set of polymeric chains, which are linked together chemically to become a water-insoluble matrix that gently attracts and holds water molecules.

The polyacrylate structure does not bind water very tightly - a plant's root suction is sufficient to release just the requested amount - but tightly enough to prevent waterlogging or other ill effects caused by free water filling air cavities in the soil.

Potassium polyacrylate absorbs and releases soil nutrients, water-soluble fertilizer and chemicals much in the same manner as water.
