Hydrogel Crystal Soil
                     Hydrogel Crystal Soil
Agriculture, or the feeding science is mostly rain fed in 
the nation, which is erratic, unprecedented, and lower in 
required volumes, making it utmost to the usage of other 
media to channelize the need for water for plants and to 
erase drought making scenarios.
The development of Hydrogel for Agriculture has changed 
the whole scenario in the world of agriculture, most 
importantly in drought hit areas. If we look at what 
changes the super absorbent polymer has brought, we 
will find most of the problems related to crop quality and 
longevity have been solved.
Working of Hydrogel Polymer
Hydrogel Polymer mixes up with soil particles and swells up on contact with water. This 
swelling up of hydrogel behave like crystal soil, imparting water retaining property to the 
targeted areas. As soon as the conditions become dry, it starts releasing water molecules, 
which can be directly accessed by the roots of the plants. These crystals shrink when it 
releases water but it can be re-used by simply adding more water, the best thing about 
using hydrogel.
On addition of water, it will again swell up and hold the water molecules for future making 
the whole process cost effective. This also manifests another property of hydrogel that soil 
may not be needed in some cases and a seed can even develop among hydrogel beads or 
crystals.
Mechanism
Hydrogel crystal soil has a cross-linking molecular structure with a 
hydrophilic group which can absorb water to about 500 - 600 times of 
its own weight to form crystal like structure.
Hydrogel polymer acts as a water reservoir for plants and has the 
ability to trap irrigation and rain water which can be released later at 
the time of requirement over prolonged durations. Hydrogel polymer 
also absorbs nutrients from the soil that are utilized by plants for 
carrying out various physiological processes.
Hydrogel polymer demands the following:
• Increase in water retaining ability
• Allow efficient water usage
• Increase soil permeability and infiltration rate
• Decline rate of frequent irrigation
• Increase plant performance, particularly in areas prone to 
drought
• Effective in all types of soil
• Reduce the use of fertilizers and pesticides to minimum
Alsta Hydrogel is a potassium polyacrylate based super absorbent polymer 
for agriculture manufactured by Chemtex Speciality Ltd that meets the 
standard needs and requirement of the agricultural sectors. It acts as a 
controlled release system by favoring the uptake of some nutrient 
elements, holding them tightly, and delaying their dissolution. 
Consequently, the plant can still access some of the fertilizers, resulting in 
improved growth and performance.
Application of Alsta Hydrogel
• Addition of hydrogel with water
• Hydrogel is mixed with soil
• Plant grows on stable hydrogel base
• Stable supply of water and nutrients
Form & Appearance Solubility Effectiveness
White Granules Soluble in water 3 – 4 Years in Soil
