New Fertiliser - confused about dilution rates
Hi guys,
I would really like to understand how you calculate dilution rates for fertiliser based on the NPK values. I know Ray has talked about this before but I'm still confused.
I'm about to buy some new fertiliser with a better balance than the one I was using previously and with completely different NPK values. Rather than relying on the instructions on the back I would like to understand what I need.
The quoted values are 2.2:1.3:2.1 so what dilution rates does that mean I should use if I want to fertilise weekly.
