Alsta Hydrogel Super Absorbent Polymer - Hydrogel Agriculture
Hydrogel Polymer marketed by Chemtex Speciality Limited under the name Alsta Hydrogel is a water retaining agent with the capacity of holding up to 400 – 600 times water than its own weight. Hydrogel agriculture or the use of super absorbent polymer for agriculture refers to hydrogel polymer application in soils for the purpose of stably providing water to the plants irrespective of drought and dry seasons. The plants can absorb water from this nontoxic water absorbent polymer throughout. Hydrogel in Agriculture is a potassium based super absorbent polymer acting in drought prone areas and rain-fed agriculture as a water retaining agent.

5. Application rates<br />
Considering the efficiency of hydrogel in soil conditioning and moisture retention, it can be understood that an optimum<br />
mixing ratio is needed to get maximum efficacy of the method. Since the moisture holding capacity is a function of soil<br />
characteristics, dosage of hydrogel is also varied and designed based on the type of soil it is used with. A simple dosage<br />
chart has been illustrated herein but the ultimate quantity and application can only be determined after testing specific<br />
soils to be conditioned.<br />
Type of Soil<br />
Arid & Semi-arid Regions<br />
For all level of water stress treatment and improved irrigation period<br />
To delay permanent wilting point in sandy soils<br />
To reduce irrigation water by 50% in loamy soil<br />
To improve relative water content and leaf water use efficiency<br />
To reduce drought stress<br />
To prohibit drought stress totally<br />
To decrease water stress<br />
Suggested dosage of <strong>Hydrogel</strong><br />
4-6g/kg soil<br />
2.25-3g/kg soil<br />
0.2-0.4g/kg OR 0.8% of soil whichever is<br />
more<br />
2-4g/ plant pit<br />
0.5-2.0g/pot<br />
0.2-0.4% of soil<br />
225-300kg/ha of cultivated area<br />

ALSTA HYDROGEL: SUPER ABSORBANT POLYMER for AGRICULTURE<br />
ALSTA HYDROGEL is a potassium polyacrylate based super absorbent polymer manufactured by Chemtex Speciality<br />
Ltd. for agricultural sector. The granular polymer has a capacity to absorb water 300-500 times its own weight and release<br />
it gradually directly to the plant roots over a period. It is effective at reducing irrigation frequency, maintaining soil<br />
texture and permeability while ensuring proper and healthy growth of the plants themselves. It can be used conveniently<br />
with de-ionized and de-mineralized water to retain soil moisture as well as reduce use of synthetic NPK fertilizers.<br />
ALSTA HYDROGEL is non-toxic and does not bioaccumulate. Under proper soil conditions, it has a long working life<br />
without any adverse impact on the agro-ecosystem. It is an easy to use farmer friendly product compatible with a large<br />
array of soil types. It finds large scale applications in Open Field & Protective Cultivation, Terrace Farming, Vertical<br />
Farming, Domestic Gardens, Arboriculture, Bare Root Dripping, Hydro Seeding, Hydroponics etc.<br />
The salient features of ALSTA HYDROGEL include:<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
Reduction in fertilizer and herbicide leaching<br />
Improvement in soil and soilless media characteristics<br />
Enhanced seed germination and seedling growth<br />
Increases root growth and density<br />
Moderates drought stress significantly<br />
Reduction in nursery establishment period<br />
Reduction in irrigation frequency<br />
Prevents premature defoliation<br />
Increases fruiting/flowering density<br />
Increases overall growth and plant biomass<br />
ALSTA HYDROGEL is the economical and eco-friendly step to a better water management system for all types of<br />
agriculture systems, especially in arid and semi-arid regions without compromising with the crop yield.
