Background info: many growers recommend using lots of phosphorus for fruiting and flowering crops. It is common to see recommended NPK ratios with slightly higher P compared to N & K. Something like NPK 15-20-15 is common, or mixing in things like bonemeal (approx 0-10-0) or rock phosphate.
Looking at the JLF analysis in the JADAM book, I was worried that there is not much phosphorus in JLF, even bone meal JLF.
However, there are many growers who recommend the opposite- using fertilizers with much lower P% in the NPK. I’ve seen recommendations around 15-5-25, etc.
In the JADAM book it also says the optimum level of P in plant tissue is much lower than N and K. (NPK 1.5 - .2 - 1 , page 220 of English 2nd Edition)
I do not want to overthink this, I am trying not to focus too much on NPK, as I want to follow an “intuitive diet” for my soil and plants.
My question is this:
If you have a good fertilization program based on whole plant matter... good base fertilizer (grass, leaves, crop residue) + balanced JLF (grass and crop residue) + sea salt + small supplements of N or K to optimize... is there any real benefit of using bone meal or other ingredients with a lot of P?
