Hello fellow scientists,
This is my last question about my project, I just want some one to analyze the following please;
So right now I'm making a 3-3-3 ratio organic fertilizer, and I'm also making a 3-3-5 ratio organic fertilizer. keep in mind these are per ton.
Is the added amount correct? do not worry about the N just focus on the P and K. according to my calculation I need to add about 180kg of rock phosphate (0-33-0) for both products I'm making. and about 1 ton of ashes for potassium (0-0-3) to reach the need amount of 3-3-5 and about and 850kg for the 3-3-3. the amount are bit high because im working with 1 ton. Also my product is about 92.5% so the dry matter is 7.5%. Please help
Mikkelsen, Robert. 2008. Managing Potassium for organic production. Better Crops 92(2):26-29.
I like this reference which is very practical on potassium resources for organic production.
Langenite is an organically certifiable resource as a crude crushed rock with 18 K, 11 Mg, and 22 S this might be useful for your consideration. It might be more concentrated as K resource and is goof for Mg also.
Please add the sufficient quantity from differanr sources of fertilizer, whee we can adjust the nutirne contnent in it as per their proportion.
