Ask your Alsta Hydrogel for Agriculture

Hello Alsta Hydrogel!

Firstly, congratulations on your widespread presence in such a limited time. Found you on Google. You have been getting a lot of appreciation and acceptance globally for your extraordinary performance.

All the credit goes to the brilliant team members of Chemtex Speciality Limited who work tirelessly round the clock in making me better, more public-centric, experimenting with newer tech and what not…

Tell me one thing, what according to you made this possible?

The issues with fresh water available are not oblivious to people; it has been the biggest issue with agriculture (almost two-fifth). A number of discussions on this issue predicted a sharp decline in agro sector’s water potential specially in Asian and African subcontinents.

These regions face severe water crisis due to insufficient and uncertain rainfall, affecting agriculture the most. It consumes most of the available potable water and what must worry us all. These areas still follow conventional practices which not only lower the effective use of water but also decrease the use of available water for crops.

Your application puts an end to these problems?

No, but these effects can be countered for a considerable period of time.


Potassium polyacrylate based hydrogel agriculture, laying low in the soil, expand upon contact with water molecules that are able to retain water for longer periods of time and release according to the needs of the crops. These swollen particles behave like tiny water crystals which impart water retaining property directly to the plant roots and the vadose zone. It does not let the surrounding soil conditions dry up, making water directly accessible to the roots of the plants. These crystals deflate or contract upon release of water but it can be re-used by simply adding more water. On addition of water, it will again swell up and hold the water molecules for future making the whole process cost effective and hassle free.

Q: Even Sodium Polyacrylate is a super absorbent polymer, then

Sodium and Potassium Polyacrylate both function as a moisture retainer. But, sodium polyacrylate has a powerful water retaining ability but cannot release water. Moreover, it starts disintegrating within 170 hours into sodium salt which is not good for soil.

On the other hand, Potassium polyacrylate has cross-linking molecular structure with a hydrophilic group attached to it. This hydrophilic functional group absorbs water to about 500 - 600 times of its own weight to form crystal like structure. Though it has comparatively low water retaining capacity, it has water releasing function as well as have higher disintegration time.

Q: And Starch? It is also a polymer and self-made by plants.

Starch polymers are not minerals. Nutrients like Nitrogen, Phosphorus and Potassium (NPK) are used by plants abundantly for growth and metabolism. In fact, potassium regulates the rate of carbon dioxide intake and release, helping in the proper synthesis of ATP, enhancing water suction ability of the roots. These nutrients directly have effects on the shape, size, colour and texture. Reason, why NPK Fertilizers are always in demand.

Then we can go for them?

Usage of pesticides, fertilizers to get rid of weed and microorganisms and to add extra nutrients may provide temporary treatment to crops and soil but in bigger picture they interfere with the quality of soil, altering their natural attributes which not only has adverse effects on quantity but quality.

What USP?

Alsta Hydrogel does not depend on the quality of soil nor alters chemical composition upon application.

Okay. My next question...

Time constraints. My shipment awaits. For more information, visit our website and related articles and blogs. Bye.

Bon Voyage Alsta!
