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).
