How to get fertilizer ratios

[wapang]

Dear members,
I would like to ask anyone how to get the ratios of 12:12:17 by mixing urea, DAP and MOP. I would really be happy if anyone could help me.

HI

Please contact the soil scientist at the Krishi vigyan kendra, he will help you with the calculations. We can explain but it is a long stepwise process

Take 160 gm DAP and 90 gm MOP.......... You will get the desired NPK ratio.

No need to add urea as N content will be made up by Nitrogen in DAP.

For reference purpose...
DAP = 20% P + 18 % N
MOP = 50 % K
Urea = 46 % N

First we need to find DAP quantity by matching P content.
Then remaining N will be added calculating urea quantity.
Then Find MOP quantity for K requirement.
