Hydrogel Agriculture (Super Absorbent Polymer for Agriculture) is potassium based non-toxic polymer capable of absorbing and retaining water up to 300 — 500 times of its own size. When mixed with soil and sown at the roots of a plant, it spares 65 – 95% of water utilized. Its application is basic yet effective.
This polyacrylate hydrogel was created to develop farming in extreme climates, whether excessively hot, excessively parched, and so forth. It assists with: dry season, desertification, poor soil quality, and treatment. Rather than day by day watering, Super Absorbent Polymers permit watering once per week, sparing time, money, and water.
Super absorbent polymer for agriculture can assimilate and hold a great degree of water in respect to their own particular mass. Water-retaining polymers, which are delegated hydrogels when cross-connected, absorb fluids through hydrogen bonding with water. Their capacity to retain water is an element of the ionic concentration of the watery arrangement.
Polyacrylate hydrogel in agriculture is effective in water utilization in agricultural and horticultural crops in areas with rainfed agriculture, from little or negligible to limited irrigation conditions. It offers huge economic viability to cultivations and is a boon to dry states, called the "future generation of farming".
Hydrogel polymer/ superabsorbent polymer (SAP) are a system of polymer chains hydrophilic in nature with water as the dispersion medium. It is capable of storing more than 90% water and has a level of adaptability same as natural tissues, because of their huge water content.
Hydrogel polymer is a water absorption agent that once added to soil or substrate will absorb and hold vast amounts of water and supplements, nearly up to 400 - 800 times of its own particular weight. Hydrogel polymers formed through cross linking polymer chains (physical, ionic or shared bonding) are well known for their water absorption. Hydrogels are mostly homogeneous in nature. Super Absorbent Polymers, which are delegated hydrogels, retain watery arrangements through hydrogen bonding with water atoms. In de-ionized and de-mineralized water, a SAP may assimilate 300 times its weight (from 30 - 60 times its own volume).
Potassium Polyacrylate based Super Absorbent Polymer
Potassium Polyacrylate is a polymer of a potassium cation and acrylate with an Absorption Capacity Index in the scope of 30 - 100. This polyacrylate helps in the germination of seedlings, with plants or for transportation of plants or seedlings. It is nontoxic, harmless, and non-polluting.
Absorption Capacity Index (ACI) is defined as (weight of water saturated gel polymer minus dry weight of the polymer) /polymer dry weight.
Absorption Capacity Index (ACI) is defined as (Weight of Water Saturated Gel Polymer minus Dry Weight of Polymer) /Polymer Dry Weight
Why Potassium Polyacrylate?
Amid dry periods, sodium polyacrylate has a tendency to gather and form cross links that repress re-swelling when it is re-wetted. With a limited number of wet/dry cycles, sodium polyacrylate hinders plant development. This inhibition emerges because sodium particles in the sodium polyacrylate system are easily replaceable and these particles are absorbed by the soil particles or have a tendency of exchange with the cations on the surface of plant roots. The result is a condition that is different from an alkaline soil, which tends to affect and inhibit plant growth and soil hardening.
Dosage & Applications
More about Hydrogel Polymer
How does Hydrogel Polymer work?
Hydrogel polymer or polyacrylate hydrogel comes in crystal or powder, which jellifies upon contact with water or other liquids. These particles may be taken as mini water reservoirs in soil. It soaks up and stores water inside, with the capacity of absorbing nearly 400 – 600 times its own weight. Water from these reservoirs is released upon root demand through osmotic pressure difference. In arid areas, the use of hydrogel in sandy soils (macro porous medium) increases the water holding capacity, which significantly improves the quality of plants. Hydrogel Polymer can influence soil permeability, density, structure, texture, and evaporation rate of water through the soil. Hydrogel with excellent water absorption quality is an exceptionally helpful green and eco-friendly item for farming and agriculture fields. It can be used for farms and forestry services, sparing water for homestead and garden and enhancing trees' surviving ratio.
This aqua absorbent act as a reservoir of water and will only use the reserved resource at the time of need, allowing a better agricultural yield. Super Absorbent Polymers have a unique mechanism to absorb and retain water; discharging it only when the crop demands for it otherwise it does not lose out on the moisture level.
Reversible nontoxic nature of Hydrogel polymer
Hydrogel polymer comes in crystal or powder, which jellifies upon contact with water or other liquids. The absorbent powers of hydrogel polymer can be easily demonstrated by stirring a tea spoon of crystal or powder into a pint glass of water. The nontoxic and reversible nature of the product can be seen upon adding a solution of common salt (sodium chloride) on the crystals which then lose out water, returning to its original form.
