What is AgraGel?
AgraGel® crystals absorb and hold hundreds of times their weight in water, and then upon demand release the moisture to the plant.
AgraGel® water crystals are potassium based, cross linked co-polymers with water binding groups. In dry form, they are white, crystalline granules with a neutral pH. When hydrated, they become a gel which retains fluids. Agragel® excels even under soil pressure, and in the presence of fertilizers and other soil additives.
AgraGel® water crystals are characterized by high volume absorption and fluid retention. Agragel® is available in a variety of crystal sizes for various soil requirements.
AgraGel® water crystals are also known as water absorbent polymers, water holding polymers, water retaining polymers or even just polymer crystals.
AgraGel® (T-500)
NOTE:The only difference between AgraGel® T-400 and AgraGel® T-500 is that T- 500 is a non acrylamide polymer which is specifically formulated without polyacrylamide to comply with regulations in countries that require acrylamide free soil amendments.
Of all plant polymers now available, AgraGel® water crystals have the greatest absorption under soil pressure. They also perform more effectively in the presence of fertilizers and other water soluble soil additives.
AgraGel® water crystals remain actively effective for more than five years with a single installation, dependent on the number of hydration cycles.
These factors on Agragel® result in the most cost effective and productive soil polymer on the market!
- Affordable cost
- Reduced irrigation requirements
- Fertilizer savings
- Significant increases in crop yields
How AgraGel® works
- When water or fluids come into contact with TeraGel® (T-200) water crystals, an electrical force pushes the inward structure of the particle away from the center via electrical repulsion.
- Small voids are created inside the particle drawing the water inward which results in rapid swelling of the crystal.
- When the water evaporates or is taken up by the plant the particle shrinks and is ready for the process to repeat.
- These reservoirs of water crystals (hydrogels) are evenly dispersed throughout the plant’s root zone.
- When the soil dries out and reaches 50% of field capacity the crystals are engineered to release their moisture to compensate for the outside soil pressure on the gel wall.
- This promotes the roots to grow to the new found moisture source provided by the presence of the hydrogels, or commonly known as water absorbing polymers or water crystals.
- In many cases the roots grow right through the hydrated water crystals, extracting the moisture before moving on to the next closest one.
- This process promotes increased root mass resulting in larger plants and increased crop yield.
- It has universal use as a soil polymer for landscaping, as a soil polymer for nurseries, as a soil polymer for horticultural use as well as a soil polymer for agriculture.
