NPK ratio of my fertilizer

Hi Experts
How can I know my fertilizer NPK ratio?
Please your help required
My fertilizer contains following ingredients
1) Mustered/Cotton Oil Cake powder
2) Dry Alpha Alpha powder
3) Wood & paper ash
4) Wood powder
5) Egg shell powder
6) Some old iron nails

Hi Ishkan ,

Perhaps have it tested ... by an agricultural college or a high school science department if you can afford it. etc.????

In the northen hemisphere we can buy a simple test tube test kit , for us it is very cheap but for you it may be very expensive .



Look on www.ebay.uk and enter " soil test kit " so you can see what I'm on about.



Question :- why the iron nails in your mix .. I've always understood that they do not give the type of dissolved iron found in soils , you would need to find out what sequestered iron is instead .

Certain plants have this sort of iron in them , so composted plants of the same type should start giving you the iron . Too much of this type of iron in the soil will make it acid and difficult to produce good crops from.

Do you grow Comfrey or can you get it ? This has all sorts of nutrients in it when rotted down or infused in cold water for a few weeks " Bocking 14 " is a well researched type for gardening.

Adding well rotted animal dungs from goats , cattle and fowls to the soil will also give lots of very very valuable nutrients that would otherwise cost you lots of money.

Hi Plantiod
Thanks for reply.
Comfrey is not available here that why I am using Alpha Alpha.
Using animal manure is very dangerous when you are growing in containers if manure is not old enough it burn your plants.
I am using my fertilizer in guava, gooseberry, sapodilla, grapes, falsa, pomegranate, mint, papaya, jambolan and date palm.
So I need to know the NPK value of my fertilizer recipe so I can add the required ingredient in my organic fertilizer.
I am sure you understand it.

OK Ishkhan , I understood right from the beginning about you wanting to test , but was thinking of what you were doing and ways of doing things that would not need you to test you growing soils.

Let me have a think and a play online & I'll see what I can find out and then I'll comne back to you.

hi Iskhan,

I have spent quite a few hours today trying to locate a website or information on line that gives information on making up your own chemical test kits for finding out the N P K of your soil .

Sadly there are not any places that I can find any thing about developing / making your own testing for NPK .

One thing for sure is that you would have to have precie weighing and measuring out devices a fairly big range of chemicals to make the reagents needed for the tests as well as a decent qualification in higher levels of chemistry . You would also need to develop your own comparison colour chart to indicate the levels of chemical s found .

Perhaps you could find out more information by joining a chemistry at home interest site .... if such things exist .

If you can afford it buy a garden soil test kit on line perhaps made in China via an eBay site or similar .

sorry I can't help you further

Hi Plantiod
Thanks for your efforts and time.
currently I am using my fertilizer on gooseberry, jambolan, papaya, grapes, mint, sapodilla e.t.c. with no problem but some experts says may be your fertilizer giving problem when fruits plants become tree and you can't rectify the issue until you know the NPK value of your fertilizer.
That's why I ask this question.

In that case Iskhan I'd go back to the " Experts " and ask them how they would do the soil tests and where to get them .

My thoughts are now ... get making your animal dung & vegatation based compost over the next six months . When it is well rotted down use it as a top dressing around the base of the shrubs scratch it in the soil & water it well , so that the root systems can take the available nutirent up .

Also dig some in in the areas you are going to plant edible crops a few weeks before you plant them again water it well if you are in a low rain area so it leachs the compost's nutrients out into the soil in time for the plants to take advantage of it.

Man has been doing this for thousands of years and it works , I doubt that you will ever get an imbalance of great defficiency of nutrients .
