Why do you use different amounts of acids to correct pH with different source water even if both areas have the same source water start pH?

To correct pH either acid (pH lower) or alkali (pH raise) is added to the nutrient solution. The acid or alkali should be diluted before addition to the solution to prevent a localized chemical reaction from occurring as it enters the water. Any reaction here can gradually precipitate out vital nutrients and alter the nutrient balance. It is normal to dilute to below 5% for this purpose.

Upgrading Fertigation on  budget?

We often are contacted by growers who want to achieve more with their fertigation but do not have a large budget to achieve this and have existing infrastructure that works well but is poorly controlled.

Our control systems can be connected to any peripheral dosing systems and we often use existing infrastructure to create a new system with everything and more that the grower requires.

Existing in fracture often used for new system installations by us:

• Pumps

• Tanks

• Dosing systems

• Pipes and solenoids

The advantage is obviously that the grower receives a state of the art control system at a price that that fits within their budget because they use existing infrastructure.
