Aquadiamonds
water retainers for soil and substrates
Human activities require more and more resources - among them water is
certainly the most precious. Modern agriculture consumes almost two thirds of the waters pumped worldwide. For this reason, more and more people are seeking ways to conserve it.
AQUADIAMONDS is a water retainer that, when incorporated into a soil or a substrate, absorbs and retains large quantities of water and nutrients. Unlike most products that become hydrated, AQUADIAMONDS has the property of easily releasing the absorbed water and nutrients, thereby allowing the plant to have water and nutrients available at will as a function of the absorption - release cycles.
AQUADIAMONDS:
Ø
Increases the Water Holding Capacity of soils for several years. Irrigation frequency may be reduced by 50%.
Ø
Limits losses of water and nutrient due to leaching.
Ø
Reduces evaporation from the soil.
Ø
Improves the physical properties of compact soils through good aeration.
Ø
Enhances plant growth. Water and nutrients are continuously available in the root zone for optimal absorption by plants.
Ø
Protects the environment against drought and groundwater pollution.
AQUADIAMONDS is a range of superabsorbent anionic polyacrylamide polymers. They are crosslinked copolymers of acrylamide and potassium acrylate that are water insoluble.
AQUADIAMONDS products have the property of absorbing up to 500 times their weight in distilled water and they become gels.
HOW IT WORKS
The polymer consists of a set of polymeric chains that are parallel to each other and regularly linked to each other by
cross-linking agents, thus forming a network. When water comes into contact with one of these
chains, it is drawn into the molecule by osmosis. Water rapidly migrates into the interior of the polymer network where it is stored. As the soil dries out, the polymer releases up to 95% of the absorbed water into the soil.
COMPOSITION
The quantity of cross-Linking agent enables modification of the polymer network:
The more the polymer is cross-linked, the tighter the network.
Thus absorption capacity decreases but the polymer remains more stable over time.
Conversely, the Less cross-linking there is, the looser the network. Absorption volume increases, but stability is reduced.
