Hydrogel agriculture

Hydrogel agriculture a functional polymer which can absorb plenty water and turn water gel form.

What the particularly amazing party is, water gel’s absorption ability is stronger than soil’s but weaker than roots of plants.

So hydrogel (in) agriculture is more like a “mini- reservoir”: to retain water when it’s raining and to release water when it’s drought.

Tips: the specific retention of the hydrogel is 1.3-1.4 MPa and the specific retention of roots is about 1.6-1.7 MPa.

Different type of hydrogels

Most hydrogels (in) agriculture’s ingredient is potassium polyacrylate – a kind of superabsorbent polymers.

Accord different graft technology, we can find the hydrogels as follow:
