Ngokubanzi, zintathu izizathu zokuba umhlaba uguqule ubomvu kwaye luhlaza:
Okokuqala, umhlaba uhlisiwe.
Ukwahlula-hluhana lomhlaba kubhekiselelwe ekunciphiseni kwexabiso le-pH. Emva kwethuba elingaphezu kweshumi leminyaka yokutyala kwimimandla ethile esemantla, ixabiso le-pH yomhlaba liye layeka ukuya ngaphantsi kwe-3.0. Nangona kunjalo, i-PH Gingulu ilungele uninzi lwezityalo zethu ziphakathi kwe-5.5 kunye ne-7.5. Kungacinga ukuba kwimeko ye-acidic, zinokukhula njani izityalo?
Isizathu soCwangciso loNcedo lomhlaba sisicelo sexabiso elikhulu le-acidic ye-cidic, njenge-potassium chloride, i-potassium pulfate, i-ammonium chloride, i-Amonium ye-Amonium, kwaye kunqabile ihlawulwe ngamanzi emvula. Ngokwanda kweminyaka yolimo, ukuqokelelwa kwee-acid ze-acid eqongeni kuya kuba nzulu, kukhokelela kwi-acidi dirocial.
Okwesibini, umhlaba uye waba yintsapho.
Ukusetyenziswa kwexesha elide kakhulu kwezichumichiza zekhemikhali kwenza ukuba kube nzima kwisityalo somhlaba ukuze sifumane ngokupheleleyo kwaye ekugqibeleni sihlale emhlabeni. Ngapha koko, izichumisi ziyityiwa ye-inrganic, ezibangela ukwanda komxholo wetyuwa umhlaba weGreenhouse. Emva kokuphuma kwamanzi, ityuwa ihlala ikumhlaba womhlaba kwaye ngokuthe ngcembe ijika ibomvu emva kwe-oxidation. Umhlaba otyunjiweyo ngokubanzi unexabiso eliphezulu le-pH, elinokususela kwi-8 kuye ku-10.
Okwesithathu, umhlaba uye waba ngu-Eutrophic.
Isizathu seli mpahla kukulawulwa kwentsimi engalunganga, nto leyo ebangela ukuba umhlaba umenze lukhuni kwaye ungabonakali, kwaye i-ion yetyuwa ibangelwa kukuqokelela i-elvaporation egqithileyo emhlabeni. Ngenxa yokuba ityiwa ityetyisiwe emhlabeni, ilungele enye i-algae ukuze iphile. Ukuba umhlaba womile, ialgae ife, kwaye intsalela ye-algae ibonisa bomvu.
Ke indlela yokusombulula njani i-phenomenon yomhlaba obomvu?
Okokuqala, kuyimfuneko ukufaka isichumisi ngokufanelekileyo.
Ukucutha ukusetyenziswa kwezichumichiza zekhemikhali kwaye kudibanise ukusetyenziswa kwezinto eziphilayo nezichumisi. Ukukhuthaza ukusetyenziswa ngokuphumelela kwechuma kunye nokulawula i-acidity yomhlaba kunye nealkalinity. Ukuphucula ukwakhiwa komhlaba.
Okwesibini, indlela yokunkcenkceshela kufuneka ibe nengqondo
Guqula ukusuka kunkcenkceshelo lwezikhukula zokunkcenkceshela ukunkcenkceshela, ukugcina amanzi kunye nesichumisi ngelixa kuncitshiswa komonakalo womhlaba.
