The benefits
■ Perfect iron availability for root uptake
■ Best chelate under high pH conditions up to pH 10
■ 100% water soluble micro granules
■ Highly efficient ortho-ortho complex in
– Basafer® Plus: 83 % ∞ (5 % out of 6 % Fe)
– Basafer®: 58 % ∞ (3,5 % out of 6 % Fe)
■ 2 Basafer® options in different pack sizes for commercial
consideration (Basafer® Plus is recommended in technically
advanced farms)

The effect
■ Iron is found in abundance in most soils but is frequently
not plant-available.
■ Particularly under unfavourable pH conditions and/or the
presence of bicarbonates, iron is tightly bound within the
soil or water-soluble.

Iron shuttle effect:
No Basafer® Basafer®
Soil bound iron is abundant, but unavailable EDDHA chelate to carry soil bound iron into the plant
otho-ortho complex with constantly 6 connections within the
structure is highly stable
■ Example: Fe++ +2OH- ➙ Fe(OH)3 (insoluble).
■ To keep iron water-soluble a chelate (Greek: claw) complex
is required; salts like sulphates are often inefficient.
■ Complex organic molecules such as iron EDDHA chelates
develop 2 different complexes with differing soil stability.

How to apply
■ Basafer® / Basafer® Plus can be used both as a protectant and curatively against iron deficiency symptoms
(e.g. chlorosis at young leaves).
■ The product can be applied to the soil surface or used by fertigation systems like drip irrigation.
■ Iron deficiency can be induced by alkaline soil conditions (pH > 7).
