Hello, I have a query, what I can understand you are not calculating N value in molecular weight as it is already in N form, but, what if I have a fertilizer which has nitrogen in Nitrate (NO3-) or Ammonia (NH3) form, do I need to convert the N value then by the same method you have shown in this video? e.x. for Ammonia to get correct N value do I need to deduct molecular weight of 4 Hydrogen atoms from NH3 to get correct number of N value in Ammonia?

No, it's not necessary to do that

The thing that is super confusing to me is why do they call it an npk ratio when it's not a ratio but a percentage? Can you explain this to me. Some people further add to my confusion when they actually use it as a ratio, for example a product with npk value of 24,6,6 has an npk ratio of 4:1:1 Is it a ratio or percentage?

Technically, the ratio is missing a fourth term being the filler, but is not included because it is implied. Ratios when speaking generally are comparisons of qualities; thus, whether it is a ratio comparing percentages, that is allowed.

@@happydays2190 100% represents the entire weight. If you subtract the terms of the ratio from 100%, you get a percentage that is not nutrients, which we call the filler.

A ratio comparing percentages, but what makes it special is that the filler part is not included as a term, hence not your conventional ratio

What if the numbers are given in decimal format like 0.21-0.11-0.16 is that the same as 21-11-16?
@StudyForceOnline Жыл бұрын
Unlikely, as I have seen them written in decimal only to mean less than a percent. Are there any other details given?

Conversion of K2O to K also seems wrong. If K2O is 7.5 lb, K should be 6.2257 lb not 1.8675 lb.
