one of the key elements is being alive to create a Eco system within your soil the only thing toy could break down like this is your base NPK all the microbes and beneficials would have to be bought wean your ready to use they have a shelf life of a day or 2 wean you make your own tea or 18 months for some but you could just but guanno bone meal eathworm castings and save them
or if you want to experament make a tea than keep it bubbuling in the dark untill you can than place in a pyrex dish and evaporate the rest but i dont think it will work
