The blood proteins are quickly broken down to ammonia from soil bacteria. In warm damp circumstances that favor bacterial development, blood meal decomposition reaction may be too fast. Ammonia possibly discharged in heavy enough amount to harm fragile roots.
i dont think that the fully ammended soils let you underfeed enough at the end of maturation to get a proper fade
top dress and organic teas much easier imho
i love the fact that the real art is the state of the secondary metabolites and the calyx they are attached to
i find a lil underfeeding at the end, however you achieve it (naturally the cold soil reduces microbial life ) reduces the composition of the stores (such as N) in the flowers but not the oils
smoother smoke regardless of how white it is
Don't think this is true. I have seen with my own eyes plants fade with plenty left in the amended soil.
Chilation makes nutrients soluble correct??
Typically, more soluble (in water) than in their non-chelated form?
and because of this solubility, chilation also improves bio-availability correct?
There is just a minor amount, relatively speaking, that has been discovered concerning natural nutrient uptake by plants. There is research supporting what Spurr has stated but pretty much zero research supporting Tyrone's statements (re: reason to flush). Additionally there is 'some' research indicating the plant's ability [maybe through a form of biofeedback] to self-regulate or block nutrient uptake in a natural growing environment. [perhaps Spurr has a citation for this subject]
I think to visualize that there is an abundance of bioavailable organic nutrients sitting as a pool waiting to be sucked up is unrealistic.
Nature is not like that. There is always a cleanup or storage crew on hand to use up or lock up bioavailable nutrients.
As we are learning more and more, we find that nature usually has a back up plan; more than one way to uptake or use up nutrients.
As far as bottled organic nutrients containing soluble (meaning ionic form) nutrients, if this were the case, would this not be indicated on the label [NPK analysis]?
Otherwise is it just another company which may have stuck in some soluble chems?
here is some basic info about blood meal

"(xxiii)"Organic fertilizer" means a material containing carbon and one (1) or more elements other than hydrogen and oxygen essential for plant growth, and allowed for use under the Organic Foods Production Act of 1990, as promulgated by the United States department of agriculture "National List of Allowed and Prohibited Substances" rule;"
3. below are other sources of info about label law for organic fertilizers. This made me sad and angry after reviewing the rules again, it's like there is no truth in advertising:
- When the term "organic" is used in the label, labeling, or advertisement of any fertilizer, the water insoluble nitrogen must not be less than 60% of the total guaranteed nitrogen so designated.
- The "guaranteed analysis" section of the label is divided into the percentage of total nitrogen, which is the sum of all forms of nitrogen present in the mixture, available phosphate, soluble potassium, and a statement of each secondary plant nutrient present in the mixture. The chlorine content is guaranteed as the maximum percentage present, when applicable, in agricultural fertilizer. Specialty Fertilizer, 49 pounds and less, designed for home and garden use, is exempt for the chlorine requirement.
Total Nitrogen:
Nitrogen may be included in the form of: (1) nitrate nitrogen, (2) ammoniacal nitrogen, (3) water soluble nitrogen, (4) urea nitrogen, (5) water insoluble nitrogen. A statement of the percentage of each form present in the fertilizer must be given. Nitrate nitrogen includes all of the nitrate (NO3 - ) forms in the fertilizer mixture. Ammoniacal nitrogen includes all the ammonium forms of nitrogen in the fertilizer. When urea is present it may be guaranteed as water-soluble nitrogen or urea nitrogen.
Water-insoluble nitrogen originally meant such natural organic materials as dried blood and tankage. Recently, however, many forms of water-insoluble nitrogen have been developed so that now any water-insoluble source is included in this figure. Insoluble sources may be materials such as urea-formaldehyde, isobutylidene diurea, magnesium ammonium phosphate, or other similar materials. A product made by coating urea with sulfur is also sparingly soluble for a period of time in the soil, but the method of analysis used in the fertilizer laboratory currently prohibits the characterization of the material as a water-insoluble nitrogen source. The natural organic sources become available by microbial action that converts the nitrogen first to ammonium and then to the nitrate form. Some water-insoluble nitrogen forms are rendered insoluble by coating with sulfur or plastic-based materials, by chemical combination with other elements, or by inhibiting the activity of microorganisms that release the nitrogen from insoluble forms. Many of these sources are treated in such a way as to provide for a long continued release of nitrogen. Listing of source materials in which availability of nitrogen is controlled through slow hydrolysis of water-soluble organic compounds shall constitute a claim of slow or controlled release of a nutrient, and a guarantee for such nutrient sources is required.
so essentially letting the medium dry is a flush,
What do you mean by dark period "to halt respiration"? Plants do not carry out respiration during light period (daylength) from photosynthetic tissue (that which is above ground like leafs) unless they are not functioning properly. It's bad if the plant leafs carry out respiration, that's called 'photorespiration' and it means the leafs are not taking in Co2 like they should be (internal Co2 levels are low). This can happen if the plants are provided too much light, too dry atmosphere, too dry media, etc., it's caused when stoma close down (i.e. reduced stomatal conductance).in conjunction with a dark period (to halt respiration) would suffice to reduce the amount of what?
