About Us 
Shimikaran Sabz Touba Co. (Touba Green Chemists) is established by a group of chemists and biologist in the field of plant nutrition that work specially on biocompatible iron fertilizer. We started by producing industrial materials like MCA, EDTA, … and then expanded our work for producing Sequestrene fertilizers such as FeEDDHSA, FeEDDHSA, FeEDDHSA and FeHEBD. At first we have produced EDDHSAM (EDDHSA Modified), SHBED and then we focuced on FeEDDHSA that it is best iron chelate for Iran’s soil and climate .

Becasue of toxicity of phenol, in all iron chelate we use para sulfonated form of phenol that it is  less toxic and more eco-friendly . Chelate like FeEDDHSA, Fe-SHBED and FeEDDHSAM.
