Effects of agricultural hidrogel

Published in: AGRICULTRE SAP

Hidrogel(Potassium polyacrylate) is a kind of extremely hydrophilic three-dimensional network structure gel. It swells rapidly in water and can maintain a large volume of water without dissolving in this swelling state.

Due to the cross-linking network, the hydrogel can swell and retain a large amount of water, and the amount of water absorption is closely related to the degree of cross-linking. The higher the degree of crosslinking, the lower the water absorption. This characteristic is much like a soft tissue. The water content in the hydrogel can be as low as a few percent or as high as 99%. The aggregate state of the gel is neither completely solid nor completely liquid. The behavior of the solid is that it can maintain a certain shape and volume under certain conditions, and the behavior of the liquid is that the solute can diffuse or penetrate from the hydrogel.

As a material with high water absorption and high water retention, hydrogel is widely used in many fields, such as drought resistance in arid areas, and oil drilling fluid in petrochemical industry. It is worth noting that different polymer materials should be selected for different application fields to meet different needs.


Agricultural hydrogels can quickly absorb and retain rainwater or irrigation water in the soil without leakage, thereby ensuring sufficient water in the rhizosphere and slow release for plant use. Its unique water absorption, water storage, and water retention properties play a role in determining the success or failure of the project to improve the ecological environment and prevent wind and sand. It is widely used in land desertification control, agricultural and forestry crop planting, landscaping and other fields.

Effect difference

Affected by many factors such as climate change, soil types, crop types, and usage methods, the effects of agricultural hydrogels in practical applications are usually different. Hydrogel agricultural experts provide you with large-scale application solutions.
