Fertigation and water soluable fertilizer

[mwardlow]

I just used my Dosatron for the first time so I'm new to this. For those who are using a Dosatron or similar equipment to fertigate. What brand of water soluble fertilizer and NPK ratio are you using? How often do you use it, weak weekly or stronger monthly, and do you use it to supply other nutrients that might be needed at the same time or separately? Peters professional 24-8-16 tropical looks promising but maybe a little to rich.

Thanks

It all depends on what you are growing in your garden.

Hi Josh, I assumed posting on the forum discussing palm trees it was obvious. To clarify, I am growing palm trees   And sorry for the misspelling of soluble, I couldn't figure out how to edit my first post.

I have an EZ-Flo Fertigation system that I have hooked into my main line.  I usually use their landscape formula which is a 24-13-8. It waters every time my sprinklers run.  I have it set at the slowest feed and I top off the 1 gallon tank every month. Right now I am trying out their cool weather blend which is 18-8-18.

Thanks Jesse. I looked up the EZflo settings and slowest feed is 15000 to 1. Do you use it set to that year round or increase the setting in the summer?

I don't change the feed setting.  I control the amount by changing my irrigation timer.

Thanks Jesse!

Resurrecting this thread….

 

I Just bought and hooked up a Dosatron D14MZ2 which apparently is the newer version of the D16 unit others have used on this forum. Really excited to see if the financial setback of purchasing two of these units and hooking them up (I bought another unit for my back yard) will produce results. 
 

After some research, I’m going to run the concentrated solution at approx 150ppm and I have the Dosatron set to 1:100 ratio. If my calculations are correct, this would require approx 11oz of water soluble powder for each gallon. Water soluble fertilizer is Grow*More 18-6-18. 
 

I put in a backflow preventer at my main line prior to the line that services my irrigation system, a check valve and filter at the Dosatron. Pressure regulator is set to 25psi and plan on injecting every watering via drip irrigation. Temporarily have a 5G bucket for the solution but that’ll change soon. 
 

I think I’m set up good but interested on anyone else’s set up, concentrate numbers, ratio settings and if this whole thing is worth it? Due tell….

 

Thanks
