Ubutaka ibinyabuzima na humus ntabwo ari bimwe. “Humus” bivuga itsinda ryigenga ryigenga kandi ritandukanye, naho “ubutaka kama nubutaka” nibintu byangiza munsi yubutaka ku bipimo bitandukanye.
Humus twese hamwe tuvuga ahanini ikubiyemo ibyiciro bikurikira:
Acide Fulvic: humus yumuhondo cyangwa umuhondo-umukara, gushonga mumazi mubihe byose bya pH, kandi ifite uburemere buke bwa molekile.
Acide Humic: humus yijimye yijimye iboneka mumazi gusa kubutaka burebure pH kandi ifite uburemere bwa molekile buruta ubwa acide fulvic.
Acide yumukara humic: Humus yumukara, idashobora gushonga mumazi ku giciro icyo aricyo cyose cya pH, ifite uburemere buke bwa molekile, kandi ntabwo yigeze iboneka mubicuruzwa bikomoka kuri alkali bivamo aside aside.
Gukoresha ibintu kama birashobora gukora neza mikorobe yubutaka. Ubutaka bwumucanga bufite ubushobozi buke bwo guhanahana cation kandi biragoye kugumana cation yintungamubiri. Iyo amapfa akwirakwira no kubura humus, ubutaka bwumucanga ntibushobora gufata amazi. Kubera ko amazi nintungamubiri biboneka mugihe gito nyuma yo kubisaba, umucanga uri mubihe by "ibirori cyangwa inzara".
