1. PolyCarb Series products are metal ions chelated with Low Molecular weight Lignosulphonates (LS).

2. LS are a by-product of the wood pulping process and hence a ‘Natural’ chelating agent used as a nutrient carrier for liquid/foliar fertilizers.

3. PolyCarb Chelates have excellent binding & surfactant properties that ‘prolong leaf uptake‘ & this is a significant factor in ‘increasing foliar nutrient efficacy’.

4. PolyCarb Chelates are ‘5-8 times more efficient‘ than sulphates.

5. PolyCarb Chelates are the most widely used foliar chelate in Australia, well ahead of EDTA, amino acid & fulvic acid.

6. PolyCarb Chelates are much ‘safer‘ than sulphates, chlorides & nitrates which have higher photo-toxicity, physical incompatibility issues & reduced longevity.

7.Use of stronger Chelates like EDTA is not essential for foliar uptake & can actually be counterproductive since synthetic chelates bind nutrients so strongly that they are not easily released in the plant, thus reducing their availability & effectiveness.
