Hi! The percentage fertilizer would usually be given in brackets after the NPK ratio, but if that percentage is not given and there is no other value given in addition to the NPK ratio (amount of fertilizer as a fraction of total) then it is not possible to calculate the amount of filler.
Can you do a bid explaining NPK per kg per hecatre. For example 1000kg of fert in my store, for 4 hectares of macadmia fields. Lets say 0:0:97(97) How would i calculate kg per hectare
You are welcome! Most of this comes directly from the Physical Science NSC Examination Guideline document (P23) - here is the link: www.education.gov.za/Portals/0/CD/2017%20NSC%20Exam%20Guidelines/Physical%20Sciences%20GR%2012%20Exam%20Guidelines%202017%20Eng.pdf?ver=2017-02-22-100225-000 There is slightly more information in the Physical Science Curriculum and Policy Statement (CAPS) for FET Phase.
Awesome man!👌💐
How do you calculate the filler When not given?

@@SimpleScience101 thank you
I have a question. The 7.2 kg actually the filler, isnt it? The remaining is the fertilizer, that is 12.8 kg.
