Wide range of solid and liquid iron chelates, including different types and combinations of chelating agents (EDDHA and EDDHSA).
IRON CHELATES formulated to protect and enhance element availability, ensuring and facilitating the total availability of the nutrient for greater efficiency and speed in the control of iron chlorosis.
A chelate is the complex bond between the ionic form of a micronutrient and an organic molecule. This ion is “trapped” by the organic molecule, protected from interactions that can insolubilize the element and making it fully available to the crops.
The advantage that both EDDHA and EDDHSA offer is greater efficiency in unfavourable conditions, ensuring the full availability of the application.
As shown in the graph, Iron-EDDHA and Iron-EDDHSA are the only chelates stable at pH > 7.
When the soil has a pH of 6.5, the available Iron-EDDHA is only 30%.
When the soil has a pH of 8, Iron-EDDHA (o-o) and Iron EDDHSA remains 100% available.
Several conditions—including water with high mineral content, high pH soils, and the presence of carbonates/bicarbonates—can cause iron precipitation, carrying the element out of the reach of crops.
The probability of iron precipitation is even greater during fertigation, because it can interact with other mineral elements in the irrigation lines.
