Ngokuvamile, kunezizathu ezintathu zokuthi kungani inhlabathi iphenduka ibomvu futhi iluhlaza:
Okokuqala, inhlabathi isiye yacima.
I-acidizer yenhlabathi isho ukwehla kwenani lenhlabathi. Ngemuva kweminyaka engaphezu kweshumi yokutshala kwezinye izindawo ezisenyakatho, inani lenhlabathi liye lahle laze lawela ngaphansi kuka-3.0. Kodwa-ke, ibala le-PH lilungele iningi lezilimo zethu liphakathi kuka-5.5 no-7.5. Ingacabanga ukuthi endaweni enjalo ye-acid, izilimo zingakhula kanjani kahle?
Isizathu sokusetshenziswa kwenhlabathi ukusetshenziswa kwenani elikhulu umanyolo we-acidic ocidiwe we-acidious, njenge-potassium chloride, i-ammonium chloride, i-ammonium sulfate, i-ammonium sulfate, i-anc. Ngaphezu kwalokho, izinga lokushisa kanye nomswakama ngaphakathi kwe-greenhouse ziphezulu, futhi akuvamile ukhishwe ngamanzi emvula. Ngokwenyuka kweminyaka yokulima, ukuqoqwa kwe-acid ion endaweni ephezulu kuba sína ngokwengeziwe, okuholela ekunciphiseni kwenhlabathi.
Okwesibili, inhlabathi isiphenduke usawoti.
Isikhathi eside sokusebenzisa ngokweqile umanyolo wamakhemikhali kwenza kube nzima kwezilimo zenhlabathi ukuze zizithole ngokugcwele futhi ekugcineni zihlale emhlabathini. Eqinisweni, umanyolo ungosawoti we-inorganic, odala ukwanda kokuqukethwe usawoti kwenhlabathi ebamba ukushisa. Ngemuva kokuphuma kwamanzi, usawoti uhlala phezu kwenhlabathi futhi kancane kancane aphenduka abomvu ngemuva kwe-oxidation. Inhlabathi ethosiwe ngokuvamile inenani eliphakeme le-PH, elingasukela kusuka ku-8 kuye ku-10.
Okwesithathu, inhlabathi isiphenduke i-eutrophic.
Isizathu salo mcimbi ukungahambi kahle kwensimu ukuphathwa kwenkambu, okubangela ukuba inhlabathi ibe lukhuni futhi ingabonakali, futhi ama-ion anosawoti obangelwa ukuhwamuka ngokweqile aqoqe indawo yenhlabathi. Ngenxa yokuthi usawoti ucetshiswa phezu kwenhlabathi, kufanelekile ukuthola amanye ama-algae ukuze asinde. Uma indawo yenhlabathi iba yomile, i-algae iyafa, futhi izinsalela ze-algae zibonisa zibomvu.
Ngakho-ke ungaxazulula kanjani into yenhlabathi yenhlabathi ephenduka ibomvu?
Okokuqala, kuyadingeka ukufaka umanyolo ngokunengqondo.
Yehlisa ukusetshenziswa komanyolo wamakhemikhali futhi uwahlanganise nokusetshenziswa komanyolo we-organic nowokuzalwa. Khuthaza ukusebenza kahle komanyolo kanye nokulawula i-acidity yenhlabathi kanye ne-alkalinity. Thuthukisa isakhiwo somzimba senhlabathi.
Okwesibili, indlela yokunisela kufanele ibe nengqondo
Shintshe kusuka ekunijezisweni kwazomkhukhumelweni kudonsa ukunisela, ukonga amanzi nomanyolo ngenkathi kunciphisa ukulimala kwenhlabathi.
