Ogsajiinta kala diri waa qiyaasta qiyaasta ogsijiinta gaaska ee biyaha ku jira.Biyaha caafimaadka qaba ee nolosha taageeri kara waa inay ku jiraan ogsijiin milmay (DO).
Ogsajiinta kala diri waxay biyaha ku gashaa:
nuugista tooska ah ee jawiga.
Dhaqdhaqaaq degdeg ah oo ka yimaada dabaylaha, hirarka, qulqulka ama hawada hawada.
photosynthesis nolosha dhirta biyaha sida ka-soo-saarka geeddi-socodka.
Cabbiraadda ogsijiinta kala diri ee biyaha iyo daawaynta si loo ilaaliyo heerarka saxda ah ee DO, ayaa ah hawlo muhiim u ah codsiyada daaweynta biyaha ee kala duwan.Iyadoo ogsijiin milmay ay lagama maarmaan u tahay in lagu taageero nolosha iyo hababka daaweynta, waxay sidoo kale noqon kartaa waxyeello, taasoo keenta oksaydhyo waxyeelo u geysata qalabka oo wax u dhimaysa alaabta.Ogsajiinta kala diri waxay saamaysaa:
Tayada: Diiradda DO ayaa go'aamisa tayada biyaha isha.Haddii aysan jirin DO ku filan, biyuhu waxay isu beddelaan wasakh iyo caafimaad darro saamaynaysa tayada deegaanka, biyaha la cabbo iyo alaabada kale.
U Hogaansanaanta Nidaaminta: Si loo hoggaansamo xeerarka, biyaha wasakhda ahi waxay inta badan u baahan yihiin inay yeeshaan xaddi DO ah ka hor inta aan lagu sii dayn togga, harada, webiga ama marin-biyoodka.Biyaha caafimaadka qaba ee nolosha taageeri kara waa inay ku jiraan ogsijiin milmay.
Xakamaynta habka: Heerarka DO ayaa muhiim u ah xakamaynta daaweynta noolaha ee biyaha wasakhda ah, iyo sidoo kale wajiga biofiltration ee wax soo saarka biyaha la cabbo.Qaar ka mid ah codsiyada warshadaha (tusaale soo saarista tamarta) DO kasta waxay wax u dhimaysaa abuurista uumiga oo waa in meesha laga saaraa oo xooga saarideeda waa in si adag loo xakameeyaa.
