Water is an important component for lush, healthy landscapes especially in our dryer climate.
Superabsorbent polymers, or hydrogels, are specifically designed to retain and low release water to help plants thrive or cope with irregular rain and/or irrigation.
Does hydrogel decompose?
When these granuals are exposed to water again, they will rehydrate and repeat the process of storing water. This process can last up to seven years, when the biodegradable hydrogels decompose. These properties are what make hydrogels attractive to the agricultural world.
How is hydrogel used in landscaping?
Moisture released by hydrogel close to root area helps reduce stress and increase growth and plant performance. Hydrogels can reduce fertilizer leaching and reduce application of pesticides. Hydrogel works as water reservoirs round the root mass zones of the plant.
Is hydrogel safe?
2.5% Polyacrylamide hydrogel (PAAG) is a non-toxic and non-immunogenic biocompatible polymer gel consisting of 97.5% sterile water and 2.5% cross-linked polyacrylamide [8,9] (Arthramid ® Vet, Contura International A/S, 2860, Søborg, Denmark), and its biocompatibility in soft tissues has been demonstrated [10][11][12].Oct 22, 2021
How are these being used for landscaping?
Retail stores sell soil amendments with hydrogel added.
These beads can be laid using a drop spreader prior to laying turf.
Many plants benefit from the moisture retention both in landscapes and potted.
It helps care for newly planted trees during dry spells after irrigation systems are off.
It can be used to absorb and slow release fertilizers.
