How to prevent unintended contamination of liquid fertilizers

Liquid fertilizers are highly concentrated and divided into neutral, acidic and lye products. 

NeutralAcidicLye
Calcium Nitrate (CN)
Ammonium Nitrate (AN)
Magnesium Sulphate (MSN)
Magnesium Nitrate (MN)
Calcium Chloride (CC)
Fertifosk
Potassium Sulphuric Acid(KZZ)
Nitric Acid (SZ-38)
Phosphoric Acid (FZ-59)



Potassium Phosphorus Hydroxide (KFL)
Potassium Hydroxide (KL-50)
Silicon (SiL)
Potassium Carbonate (KBL)



Reactions of liquid fertilizers

Some of these products should not react with each other in undiluted forms, to prevent precipitation, gas or the development of heat. In order to prevent contact of several elements, use of the A- and B-tanks can be made. The table included below explains which two concentrated, undiluted fertilizers can get in contact with each other:
