CONCLUSIONS

Agronomic:
- The isomer "o-p" doesn't resist the interaction in the soil, and it is not capable of solubilizing native Fe in the soil. It doesn't have recharge effect as a transporter: "Iron Shuttle effect". The "o-o" yes

Economic:
   - The presence of the isomer "o-p" reduces the quality of the product and it represents an increase of application cost compare to the previous agronomical yield with ortho-ortho. The "o-o" does worth the cost.

Commercial:
   - To denominate the isomer "o-p" as Iron chelate it bears a lack of clarity as for the specification of quality of the products. The "o-o" do give good results about the quality and effectiveness.

  

Chemical:
- The isomer "o-p" with only 5 coordination places is not sufficiently stable to maintain the Iron in solution under alkaline conditions. The isomer "o-o": yes
