NPK value of everything organic!

This originally started out life as a fully searchable database for the NPK of everything organic, but unfortunately as we've migrated over to better shopping software we've lost the ability to offer that format.
Until we can get that back, please feel free to hit "CTRL + F" on your keyboard to search what your looking for. Arguably you now get the chance to see inputs you might have missed in the past, but we'll still look for a database solution.
As before, if you want something added please us the contact form to let us know!

are tobako stalks suiteable for mixing with the soil for growing vegetables?

I am a seventh grader doing a fertilizer project. Our organic fertilizer assumed the use of cottonseed meal, which in this table displays the nitrogen value as 46. However, blood meal has substantially more nitrogen than cottonseed meal. Therefore, I believe that the 46 associated with the cottonseed should be discarded and instead replaced with 4.6. Additionally, when I interrogated my teacher, his response was that cottonseed meal has ample amounts of both potassium and phosphorus and this table displays the above values as zero. Either the source in which you got this information from was wrong, or you made a typo, but I would assume that the former is more likely by a sizeable proportion. I would therefore highly recommend that you fix this small mistake so future readers can hold you in higher regard. Thank you for listening in advance.
