Rexolin®
D 12 is a product developed for usage on iron
deficient soils with acid to neutral pH and for iron deficient crops
through
foliar application. Foliar application is recommended when the soil is
neutral
to alkaline or when soil application is impossible for other reasons.
It has an
excellent performance in hydroponics systems.
Rexolin®
D 12 contains 116 grams iron per kg of product as
Fe-sodium-DTPA derived from diethylenetriaminepentaacetic acid.
Never bring
Rexolin® D 12 in direct contact with
concentrated
acids. Rexolin® D 12 is stable between
pH 1.5 - 7.5. Use chelated
zinc, manganese and copper if these elements are dissolved in the same
tank.
Keep the solution in the dark and use it within one or two weeks. Check
the
Fe-level after recirculation and add extra Rexolin®
D 12 if
necessary.
When the pH
near the roots is rising to 7.5 or higher, or when the water
used contains very high levels of zinc, it is advised to substitute
half of the
Fe-DTPA by Fe-EDDHMA (or a high quality Fe-EDDHA).
