Calcium Phosphate (bones/vinegar) vs. Phosphoric Acid (sesame stems/water) will one replace the other, is one input older?

i think this comes to knowing what the plant n soil life needs and what each do separately im no expert but it looks as if the 2 do diff things for the plants  i do believe theres a recipe also in there about making  potassium out of tobacco but its not used in the KNF recipes much at all i also think its a way to make the nutrients plants need that might not be used much but also the KNF way so u dont go out and buy but make at home

( Phosphorous acid can be injected into trees and stimulates improved rooting and pathogen resistance. When plants are colonized with mycorrhizal fungi the ability of plants to utilize soil Phosphorus is increased. )

( Phosphoric Acid is a multi-function agent, used for plant nutrition, pH adjustment and cleansing irrigation equipment (notably dripper lines) from lime precipitation. It is an RICH source of phosphorus for plants. it is suitable for greenhouse crops, open field crops and fruit trees. )

( For example, calcium bonds with phosphorus to create phosphate of calcium. The phosphate brings the calcium through the plant and drops it where it belongs. It transports all nutrients throughout the plant with the exception of nitrogen. )
