Newbie requires help getting started with Fertigation

Featured Replies

I want to use a 100 liter black plastic trash can from Makro as a starting point for a basic fertigation system. I have some Citrus plants that require a NPK ratio of 15:4:11 and I need you guys to help me work out how to buy what I need to get the mixture right.

My first question is can I buy Nitrogen, Phosphorous, and Potassium as soluble liquids or do they all come in powder form?

How do I calculate how much of each to put in with 100 liters of water?

Hello DF, WESCO in BKK has all the single chem's that are

water-soluble and micro's nutrients you need.

They have blends of W/S fertilizers that you can buy 1Kg and

25Kg bags. They ship all over LOS.

There are other Co's that also sell here to, but I am more

familiar with WISCO as I get my Hydro chems from them.

Also, if you want to do a custom blend, you can find fertlizer

calculators on the web.

Thanks. I'm in Chiang Mai but have to go to BKK next month so I'll check WISCO out.

Hello All, DF, CM is a large AG area, you should be able to find

what you need there.

1. Have you done a soil test to see what your trees need?

2. How many trees?

3. Do you use/plan to use mini sprinklers or another type of

drip system to water/feed your trees?

I use a white bucket with water and W-S fertlizer feeding into

a venturi<sp> injector between pump and filter then off to

1+ rai of drip tape for row crops.

If you search around TV-FF for "drip irrigation", there's pic's of

what I trying to write about.

The venturi injector you can pick up a and store selling Super

Products for Bt.150. to 400., they also have a large metering

pump, like a DosaTron used in greenhouse irrigation or orchards.

Here's some of WESCO's products. A I also reccomend picking

up a copy of Home Agricultural Magazine, it has adds by most

of the large fertilizer Co's that sell W-S Fert's, much easier to see

what available in 1 magazine.

WESCO also has sulphates instead of the chelates for micros

and Moly and Solubor.

The best way to fertagate, my system was much smaller for

30 sq M's. The pic is from Home Ag Magm
