Fertigation Set Up and Explanation Using a Dosatron System

Fertigation Set Up and Explanation Using a Dosatron System
Professor DeBacco

“Dosatron” = Chemical Injector
Dosatron is a name brand, but is often considered to be the industry standard.

It works in a similar way of other chemical injectors.

This is a water-powered, non-electric chemical injector.

It is easy and reliable way to accurately inject chemicals into water lines.

This class of injectors works by using volumetric proportioning which helps maintain consistent mixing rates despite changes that may occur with water pressure and flow.
Injector In Action

Water Flow
Water enters the Dosatron body
Concentrate is pulled up into the Dosatron
Concentrate mixes with the incoming water
Blended solution is discharged into the water line

Drip/Emitter Irrigation
Each container has a dedicated emitter system that can involve multiple outlets which are especially important for larger containers and plants.

However, be sure there are checks for sediment clogs in the system.

Dosatron System
Efficient method of dosing fertilizer from stock tanks

This reduces the need to mix fertilizer daily and can also ensure consistency of nutrients delivered to the plants.

These are water driven piston pumps that can be set to a ratio and adjust to the flow of water.

There will be a familiar click sound that ensure proper function and can alert you to when something may not be right.

Check valves are recommended (often required) to prevent backflow into a public water supply.
Fertilizing and Cleaning
This system can be used for fertilizing the plants
Same system can also be used for line cleaner
Importance of Filters
Prefilters should be installed to catch anything that comes in the lines before it reaches the Dosatrons.

Intake filters should be at the ends of the tubes in the fertilizer containers

Postfilters should be installed to ensure no large particulate goes out to the emitters from the Dosatrons

System Used
Part A
General Fertilizer
5-12-26
Part B
Calcium nitrate
15-0-0
Part C
Bloom Booster
10-30-20
Irrigation Line/Emitter Cleaner
Root Drip
Hyperchlorous Acid

Check the Product Label for Dosing
Typically stated for a 1:100 ratio which is what the Dosatrons are often set at.
It says add 13oz. Of fertilizer to be added per gallon into the stock feeding tank
*Given this standard ratio it also makes it easy for growers to make adjustments if they chose to.
If you had a 1:200 ratio double the concentration stated
If you had a 1:50 ratio halve the concentration stated

Let Us See it in Action…
Connor will walk us through the fertilizer injector system in action.
