Super Absorbent Polymer for AgricultureYes! I am interested
Potassium Polyacrylate based Super Absorbent Polymer for Agriculture is hydrogel polymer for agriculture once added to the soil or substrate absorbs and retains large quantities of water and nutrients, nearly up to 400 times its own weight. Hydrogel has a unique mechanism of absorbing and retaining water, discharging it only when needed, so the crops do not lose out on a stable supply of water and nutrients. Potassium Polyacrylate polymers do not interfere with water imbibing process of the plants unlike sodium polyacrylate based polymers. This aqua absorbent of water acts as a mini water reservoir and will only use this reserved water at the time of need, allowing a better agricultural yield.

Key Features and Benefits:

- Increase in water holding capacity of the soil
- Limits water and nutrient loss through soil leaching
- Reduces evaporation by locking water
- Improves physical properties of soil by enhancing aeration (airflow)
- Enhances plant growth by providing water and nutrients to the root zone of the plants
- Long term protection of environment against drought and groundwater contamination
- Prevent dehydration of the seedlings
- Reduces transplanting shock and thereby reducing mortality rate of the plants
- Mixed with cellulose mulch, it helps stable newly graded soils which are able to maintain a minimum amount of surface water
- Used in large scale farming where it increases soil aeration enhancing germination and development of roots
- When mixed with fertilizers, it can stably provide fertile nutrients to the roots for a longer period
