The Fert I am feeding the bananas is 10-2,5-15, for creating this I use Ormin-k a organic-potas fert, with 30% K2O it has a ph of 5-7,
My second ingredient ist Urea (here its called Üre) has a N of 46 %.
My third ingredient is 18-46, it has 18%N and 46% 'Fosfor`.
So When I use two bags of Ormin-K I have 15 kg net K, when I use 5,4 kg 18-46 I have about 2,5 kg P,
Whats left is the N I need 10 kg, with the 18-46 I have already 972 gr, to complete the amount I have to add 9kg and 28gr,

I went out of Urea and bought amonyum sulfat today, in my next mix I will replace urea with amonyum sulfat,
amonyum sulfat has a content of 21% N, so I have to almost double the amount.
Richard, I heard amonyum sulfat has an acidic character drops the ph-value.
Do you recommend using amonyum sulfat?
