    O teor total de \u00e1cido h\u00famico refere-se \u00e0 soma do \u00e1cido h\u00famico livre e \u00e1cido h\u00famico combinado com \u00edons met\u00e1licos de alta val\u00eancia, como Ca2 +, Mg2 +, Fe3 +, Al3 + (este \u00faltimo \u00e9 comumente referido como “\u00e1cido h\u00famico ligado”). Ele pode ser dissolvido em \u00e1lcali c\u00e1ustico dilu\u00eddo e pirofosfato de s\u00f3dio.

Exceto para o \u00e1cido h\u00famico no carv\u00e3o, a mat\u00e9ria org\u00e2nica do carv\u00e3o \u00e9 na verdade um pol\u00edmero neutro de alta mol\u00e9cula que foi “roqueado”. E os res\u00edduos da planta, como carboidratos, lignina, lip\u00eddios, prote\u00ednas e amino\u00e1cidos desapareceram.<\/p>\n

    Portanto, quando o \u00e1cido h\u00famico de carv\u00e3o \u00e9 usado como mat\u00e9ria-prima de fertilizante composto, o teor de mat\u00e9ria org\u00e2nica \u00e9 de pouca import\u00e2ncia e o teor de \u00e1cido h\u00famico deve ser usado para medir a qualidade das mat\u00e9rias-primas.

A produ\u00e7\u00e3o de fertilizantes de \u00e1cido h\u00famico geralmente exige que o teor de \u00e1cido h\u00famico nas mat\u00e9rias-primas seja de 40% a 60%, de prefer\u00eancia acima de 50%.<\/p>\n

Os \u00edons met\u00e1licos de alto valor, como c\u00e1lcio e magn\u00e9sio nas mat\u00e9rias-primas, podem facilmente formar humatos com \u00e1cido h\u00famico.
