2. Basics
Active chelate sites
PolyCarb is able to chelate metal ions due to the presence of
hydroxyl, carboxyl & sulphonyl groups
CEC
PolyCarb has a very high Cation Exchange Capacity (CEC)
due to a higher availability of binding sites in its molecule
Origin
PolyCarb being of plant origin, its chelated micronutrients are
more natural than synthetic chelates
Stronger binding sites = chelate structure

Avoids
Avoids Avoids interference
blocking precipitation with P ( in
metal to soil of metal NPK) or in
soil

4. Basics
Leaf Transversal Section
PolyCarb™ provides a good distribution of
micronutrients on leaf surface & thereby substituting
Cuticle Water the need of additional adjuvants when used with other
Water + foliar formulations
PolyCarb™
PolyCarb™ minimizes the risk of leaf scorching and so
higher metal concentrations could be used favoring
Xylem
the diffusion to the phloem
Phloem
PolyCarb™ has a lower point of deliquescence (POD)
than inorganic salts & complexes used in foliar
Stomatal Stomatal nutrition which means it can hold moisture longer &
Cavity Pore rehydrate more rapidly even in a dry environment.
Low POD helps foliar uptake rate of micronutrients

12. Advantages
Lignosulphonate is a Natural Chelating Agent
- extracted from wood pulp
Being of plant origin these chelates act
systemically and carry the metal ion through
the plant reaching everywhere they required
Once inside the plant the mineral is released
and the left over lignosulphonate carrier is
used up as a source of water soluble nutrient
These chelated micronutrients can be used
for organic food production to increase the
final nutrient value of the produce
