Hi Mlungisi! I love your channel! Your way of explaining makes things is alot easier to understand than the teachers I had 25 years ago! My problem was i did chem and organ chem back in school but did nothing related to any fertilisers :( I dont think the SA farmers wanted their secrets shared ;) lol I was wondering if you could help me work out a fertilizer with an NPK of 3-1-1? The macro nutrients i need to use are: (They are all in powder form and I need to keep them like that) Magnesium sulfate, Potassium nitrate, Ammonium phosphate monobasic and ammonium nitrate. Your help would mean a lot!

For example, in every bag or container of fertilizer. The 40% NPK in 12kg is always located at the nutrient composition/Table? So the other 60% is also in the Table?
