[Izhar]

Sorry i missed that, it is on the side of Civic center i.e. if you are coming from Hasan Square and going towards old subzi mandi, it will be on your left hand side..

I have calculated the concentration in Parts per Million (ppm): (correct me if wrong)

For dilution of 3ml solution in 1000 ml of water:

Nitrogen----------------540
Potash-----------------4.5
Magnesium--------------0.9
Zinc--------------------2.7
Boron-------------------0.9
Iron---------------------4.5
Copper------------------0.03
Manganese---------------0.3
Molybdenum------------0.000006
Cobalt------------------0.000006

For dilution of 5ml solution in 1000 ml of water

Nitrogen-----------900
Potash-------------7.5
Magnesium--------1.5
Zinc--------------4.5
Boron------------1.5
Iron--------------7.5
Copper-----------0.05
Manganese---------0.5
Molybdenum-------0.00001
Cobalt--------------0.00001

Izhar your calculations are perfect.

In my opinion Nitrogen amount present in the solution is much higher because the normal Nitrogen feeding is b/w 200-500 ppm. In the study they also used Nitrogen separately.

No phosphorous?

Phosphorus is absent because the other metal such as Magnesium or Iron will react with phosphate and form insoluble salts which is unavailable to plants.

As I under stood extra Nitrogen was added to this product. In foliar spray the PPM of N is much higher as the quantity is low.
A spray of 1% Urea is recommended for fruit trees after the fruit is formed. Now 1% Urea means4600PPM, N.
Confused

[Izhar]

and in one study 4% urea was used as foliar spray ... I think it has something to do with the form of nitrogen available like in from urea the nitrogen is in ammonium form.. due to its volatile nature, higher percentage of Urea is used... any comments??
