How much NH3 becomes NO3 - Fertilizing

dukydaf · 11-04-2006, 01:29 PM

Now I know that some will be inclined to say that the raport is 1:1. What about bacterias that transform these substances, do they reduce the N amount?
What exactly are the NO3 test kits measuring?

Thanks

To calculate how much NH3 becomes NO3 is very simple:

NH3 consists 82% of nitrogen
NO3 consists 22.5% of nitrogen

So, 1g of NH3 will give 0,82g of N. To have the same amount of N in the form of NO3 we must "place" 0,82g of N into NO3. This will give 3,6g of NO3.
Thus, 1ppm NH3 will give 3,6 ppm NO3.
