So, I've been digging into organic info a bit. A couple things strike me as odd.
- Evidently all the organic N from all the different sources are 100% ammonia!? Now in a open soil this wouldn't be an issue. In containers though does anyone monitor the NH4 to NO3 ratio in their organics? If the ferts are mineralized to ammonia too quickly, then it kills off all the nitrifying bacteria.
- Byproducts from mineralization of organics are phytotoxic to roots!!?? Evidently this is primarily why organics and hydro don't mix. Again, In open soil I don't see an issue; though is this an issue with organics and containers?
- Evidently the organic fertilizer components have a big issue with salts (sodium chloride). It seems one brand of XX may be 2.0 EC and another brand of similar XX may be 4.0 EC. Has anyone gone through the various components added and brands to compare the amounts of salt for each food?
Last I guess, The NPK ratings for organics are rated by "First year" availability. Meaning they won't necessarily provide all their N or P or K until one years time. (of course this is same rating for chemical, but it's available instantly.) So then, how does one account for this in an organic container? Does anyone factor in the rate of availability or are there any charts?
I grow in containers (3-7 gallon smart pots) and have zero issues. As for toxicity to roots of broken down minerals- soil would exist nowhere if this were a problem, plenty of other biological activity going on to remove any chance of harm.
There is some exploration and elimination work to be done. Yes inputs break down at separate rates but for me only the act of growing keyed me into those factors. Greensand, Bone meal can take some time, likewise fish bone meal so use those accordingly.
Honestly I've never considered any of the questions you posed and have had great results, improving every round, with the recipes you have.
