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!
Mr i haven't watched this topic as yet because want to understand ,The exam guideline changes from year to year, my question is which exam guideline are they using for May-June exams?( upgrading) please help me out because there's another part of organic chemistry that was not in the exam guideline last year.
What if my npk is n 5 p 6 k 6 And I’m using 5 ml in a gallon of water. what percentage of Nitrogen is in the gallon of water ? Do I say 5 % * 5ml = 25 % of nitrogen in a gallon of water.
Mr I have learned everything about photo electric effect but then I came across a question calculating the maximum wavelength in May June 2017 n I'm struggling to figure it out I went to the answer sheet to see how it's done but I'm still struggling a bit please if you don't mind I need help I'm just scared they ask a similar question again n i still don't know how it's done
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?
If I understand correctly, your country's labelling system of 5:3:4 (24) IS NOT THE SAME as an internationally available bag labelled 5:3:4 without that filler number?
Mr Nkosi, I'm currently upgrading and last year this topic was cut off so I'm enquiring If I'll need to study this topic as I'll be writing by November?

best explanation i think on you tube ,pls advise how to calculate the bracket number if not provided...
of a 19.14.29
Thank you 😊
But please don’t worry about this section. It’s not examinable if you’re writing the South African curriculum
I needed this last week
Askies, it’s here now…

What is the total mass of fertiliser you want to make?
@@MlungisiNkosi 1kg :)
How do get the 20%

The one of plastic and polymer nton nton.
This will not be examinable for May/June exams
This is not examinable this June
What if my npk is n 5 p 6 k 6
And I’m using 5 ml in a gallon of water. what percentage of Nitrogen is in the gallon of water ?
Do I say 5 % * 5ml = 25 % of nitrogen in a gallon of water.
Thank God! Been praying that you cover this chapter 🙏😂😂❤️❤️
It was covered a while back, I just published it now after much pressure
@@MlungisiNkosi okay bhutwami thanx ❤️🙏
We missed you on Physics side sir ❤️❤️
I made this last year… I thought I’d publish it for those who kept requesting.
@@MlungisiNkosi thank you sir. We probably should get you more people bcz we're indeed benefiting from you 🙏
@@bonanimbizweni2757 I love the idea of people’s destinies changing because they came across this channel. Please do bring them 😌

Get the threshold frequency first and use the f=c/y equation
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?
No… it’s not necessary
If I understand correctly, your country's labelling system of 5:3:4 (24) IS NOT THE SAME as an internationally available bag labelled 5:3:4 without that filler number?
You are correct. The above grades are for elemental P and K and not P2O5 and K2O.
This is great
Please skip this section
I also need I want to understand if this topic still on or ? I don't see it on the question papers I'm busy with
This topic is no longer assessed in the CAPS.
Perfect
Sir I am still waiting for you to release a video on stoichiometry
Please check on the playlist. There’s 4 videos on Stoichiometry
Thanks sir they are for grade 12 right ✅
Thanks sir
Please start with exponential and logarithmic functions... its giving me a problem
It will come
Question
4:1:3 (24) +0.5% Zn
Calculate the amount of NPK in kg
Try it and tell me what your answer is
P=0.96kg
K=2.4kg
Plz make 3 20 20 npk
Mr Nkosi, I'm currently upgrading and last year this topic was cut off so I'm enquiring If I'll need to study this topic as I'll be writing by November?
I’ll verify that for you.
@@MlungisiNkosi Thank Sir,I'll wait
no it's not in the Supplementaries
Thank you
Sir is this still in the syllabus, will it be in the supplementary because last year they removed it
No it won’t be. I just got tired of explaining and made it available for people who want it
@@MlungisiNkosi haii sir😂🤣🤣🤣
@@AD-hr4xf I know 🤣
@@MlungisiNkosi sir let's not talk about P2 maths😂😂😂😂
Hi sir will this topic be examined in November?
No it won’t…
@@MlungisiNkosi thank you sir
Thank you for the awesome video.... Is it going to be tested for November?
NPK fertilisers on maize?
This section has been trimmed out for now
the mass of k is 2.4kg
Thanks
You’re welcome
You’re welcome
what if the percentage is not given
I’ll show you in a future video
