Second, that cow manure, also same details as of that sewage one, making me feeling that both are almost the same regardless how both were made.

What is written in Arabic for the compositions of NPK are the following:

N: 1.5 - 3% [or 2? it isn\'t clear from that scratch on the number]
P: 1.5%
K: 1 - 1.5%
Ca: 0.5 - 0.8%

And they wrote about another materials as iron, zinc, copper,...etc, but without amount or percentage.

And what do you think about this one?
