Humus bụ ihe na-agba ọchịchịrị-agba aja aja, amorphous, ihe organic na-agbasasị agbasa nke nwere ịdị arọ molekụla dị elu nke na-emebi emebi. A na-etolite ya site na ndakpọ anụ ahụ, kemịkalụ, na microbial na ngbanwe nke anụmanụ na ihe ọkụkụ. Ya mere, ọ dị n'ọtụtụ buru ibu na ala, peat, lignite, mmiri na sedimenti. Isi ihe na-arụ ọrụ na humus bụ humic acid na fulvic acid, ma nwee obere humin. Ebe humic acid na-agbaze na alkali ma ọ bụghị na acid, fulvic acid na-agbaze na acid na alkali, na humus na-adịghị edozi na acid na alkali, na HM na-adịghị edozi na acid na alkali. , n'ihi ya, ha nwere ike kewaa ma dị ọcha ruo n'ókè ụfọdụ site na solubility. Humic acid bụ organic acid macromolecular nke nwere aromatic na otu dị iche iche na-arụ ọrụ. Ọ nwere nnukwu mmeghachi omume ma na-ejikarị arụ ọrụ ugbo, ọgwụ na nchekwa gburugburu ebe obibi na mpaghara ndị ọzọ.
Humic acid nwere usoro dị mgbagwoju anya ma dị iche iche. N'ihi nhazi ya dị iche iche, ọ nwere ọrụ dị iche iche na mmetụta. Nke mbụ, usoro nke humic acid na-ekpebi na ọ nwere ezigbo hydrophilicity. Enwere ọnụ ọgụgụ buru ibu nke hydroxyl, carboxyl na otu ndị ọzọ na-arụ ọrụ na molekul humic acid. , na-enye ya ohere ijikọ hydrogen na ụmụ irighiri mmiri iji mepụta ngwọta. Nke a hydrophilicity na-enyere humic acid aka ịkwalite agglomeration na nchịkọta nke irighiri ihe ala, mee ka nkwụsi ike n'usoro nke ala ahụ dịkwuo elu, ma melite nkwụsị mmiri na njigide mmiri nke ala.
Nke abuo, humic acid nwere ikike mgbagwoju anya. Otu ndị na-arụ ọrụ dị ka carboxyl na phenolic hydroxyl dị na mkpụrụ ndụ humic acid nwere ike ịmepụta ogige nwere ion ígwè. Ihe mgbagwoju anya a nwere ike gbanwee ọrụ na solubility nke ion metal na ala ma belata mgbasa nke ọla. Nsi. N'otu oge ahụ, mgbagwoju anya nke humic acid nwekwara ike ịkwalite ntọhapụ na inye ihe oriri na-edozi ahụ, meziwanye ọmụmụ ala, ma kwalite uto na mmepe nke osisi. Na mgbakwunye, humic acid nwekwara ikike mgbanwe ion dị mma. Elu nke mkpụrụ ndụ humic acid na-ebu ọnụ ọgụgụ buru ibu nke ebubo ọjọọ nwere ike ime ka mgbanwe mgbanwe ion na cations. Ngbanwe ion a nwere ike ime ka ikike mgbanwe ion dị ala dịkwuo elu ma melite ikike ọmụmụ na ihe oriri nke ala. Humic acid nwekwara ike imebi na desorb ihe ọkụkụ na-edozi ahụ ma na-achịkwa ntinye nke nri ndị dị na ala. Ịdị irè na nnweta. N'ikpeazụ, humic acid nwekwara ikike adsorption dị mma. N'ihi mgbanaka na-esi ísì ụtọ bara ụba na ọnụ ọgụgụ dị ukwuu nke ndị na-arụ ọrụ n'ime ihe owuwu ya, humic acid nwere ike ime ka ihe ndị na-emepụta ihe na-emepụta ihe. Mgbasa ozi nke humic acid nwere ike belata ala na-ewepụ nsí nke ihe ndị na-emerụ ahụ ma belata mbugharị na mgbasa nke mmetọ. N'otu oge ahụ, humic acid nwekwara ike ịmịkọrọ ma mee ka ihe oriri na mmiri dị n'ime ala na-ebelata, na-ebelata ihe oriri na-edozi ahụ na ikuku mmiri.
Na nchịkọta, njirimara nhazi nke humic acid nwere njikọ chiri anya na ọrụ ha. Ọdịdị nke humic acid na-ekpebi na ha nwere ezigbo hydrophilicity, ikike mgbagwoju anya, ikike mgbanwe ion na ikike mgbasa ozi. Ọrụ ndị a na-eme ka acid humic bara uru na ala na mmiri. Ọ na-arụ ọrụ dị mkpa na gburugburu ebe obibi na gburugburu ebe obibi ma bụrụkwa nnukwu ihe dị mkpa maka idobe ahụike ala na nguzozi gburugburu ebe obibi.
