hantida kiimikada

Mabda'a ka hortagga dabka:
(1) Dahaarka dab-damiska laftiisa lama gubi karo, si substrate-ka la ilaaliyo uusan si toos ah ula xiriirin oksijiinta hawada ku jirta;
Dahaarka dab-damiska wuxuu leeyahay kuleyl hooseeya, wuxuu dib u dhigaa heerka gudbinta heerkulka sare ee substrate-ka;
(3) Dahaarka dab-damiska ayaa la kululeeyaa si uu u burburiyo gaaska aan guban karin, wuxuu khafiifiyaa gaaska guban kara ee shayga la ilaaliyo si uu u burburo, si aysan u fududaan in la gubo ama loo yareeyo heerka gubashada.
(4) dahaarka dab-damiska ee nitrogen-ka leh ayaa burburiya kulaylka, sida NO, kooxaha NH3, iyo kooxda xorta ah ee dabiiciga ah, waxay joojiyaan falgalka silsiladda, waxayna yareeyaan heerkulka.
(5) Nooca fidinta dahaarka dabka u adkaysta waa xumbada ballaarinta kulul, sameynta lakabka dahaarka ee xumbo kaarboon ayaa xiran si loo ilaaliyo shayga, dib loogu dhigo wareejinta kulaylka iyo walxaha salka, looga hortago shayga inuu gubto ama ay ugu wacan tahay kororka heerkulka oo ay keento hoos u dhaca xoogga.

Soo bandhigidda badeecada iyo sifooyinka

Dahaarka dab-damiska wuxuu maraa burushka dahaarka ee dusha sare ee walaxda, wuxuu hagaajin karaa iska caabbinta dabka ee walaxda, wuxuu gaabin karaa xawaaraha faafitaanka ololka, ama waqti cayiman gudahood wuxuu ka hortagi karaa gubashada, noocan dahaarka ah waxaa loo yaqaan dahaarka dab-damiska, ama waxaa loo yaqaan dahaarka dab-damiska.
Dahaarka dab-damiska waxaa loo isticmaalaa dusha sare ee substrate-ka guban kara, kaas oo yareyn kara gubashada dusha sare ee walaxda dahaarka leh, xannibi kara faafitaanka degdegga ah ee dabka, iyo wanaajin kara xadka iska caabbinta dabka ee walaxda dahaarka leh. Waxaa lagu dabaqaa dusha sare ee substrate-ka guban kara, si loo beddelo astaamaha gubashada dusha sare ee walaxda, loo xakameeyo faafitaanka degdegga ah ee dabka; Ama lagu dabaqo qaybaha dhismaha, si loo hagaajiyo iska caabbinta dabka ee xubnaha dahaarka gaarka ah, oo loo yaqaan dahaarka dab-damiska.
