This document describes a water retainer product called PolySorbTM. It is a superabsorbent polymer made of cross-linked acrylamide and potassium acrylate. When water contacts PolySorbTM, it is drawn into its molecular network through osmosis. As soil dries, PolySorbTM releases up to 95% of absorbed water. The document provides application instructions and advantages, such as increasing water and nutrient retention in soil while reducing irrigation needs by 30-50%. PolySorbTM demonstrates no toxicity and degrades naturally into beneficial compounds.

2. Composition
Superabsorbent anionic polyacrylamide polymer
Cross-linked co-polymer of acrylamide & potassium acrylate

3. Action
PolySorb™ consists of set of chains
parallel to each other, linked to each
other forming a network
When water comes in contact, it is
drawn into the molecule by osmosis
As soil dries out, PolySorb™ releases
upto 95% of absorbed water into the
soil

Recommended Dose Recommended Dose
1 to 3 kg of dry PolySorb™ / m3 ≈ 3g dry PolySorb™ / tree
Not more than 3kg / m3 ≈ 2250 trees planted / hectare
Preferably mix hydrated with ≈ 6.8 kg / ha of dry PolySorb™
the growing media
Advantages Advantages
1. Savings of water through limited percolation 1. Reduced mortality
and spills and less evaporation
2. Application of hydrated PolySorb™
2. Soils remains irrigated for a longer time. waters the tree at planting
3. Interval between 2 irrigations is spread out 3. Possibility to plant during the dry season
4. Cost savings: saplings, labor, etc

13. Advantages
Increases water holding capacity of soils & at the same
time reduces water evaporation from soil
Increases soil aeration
Reduces irrigation frequency by
30-50%
Reduces water & nutrient losses due to leaching by
20-30%
Enhances plant growth by making water & nutrients
available in the root zone consistently for optimum
absorption

15. Toxicity
• PolySorb™ demonstrates no systemic toxicity (oral LD50/rats >
5000mg/kg)
• PolySorb™ is sensitive to uv rays and undergoes degradation to
oligomers and subsequently undergoes microbial degradation by
aerobic and anaerobic process
• PolySorb™ degrades naturally in soil into CO2, H2O & Nitrogen
compounds which are essential plant nutrients
