Umhlaba olungiselelwe ngokufanelekileyo ube yiyona nto iphambili kwisivuno esihle. Umhlaba ngaphambi kobusika kufuneka ulungiselelwe ukusuka ekwindla.
Indlela yokulungisa umhlaba ubusika?
Kukho iingcebiso ezisisiseko zokulungiselela umhlaba ubusika, ukwenzela ukuba isivuno sonyaka ozayo sivuyiswe ngobuninzi kunye nobunjani. Masihlalutye imithetho ephambili:
- Umgquba omtsha. Ngokuqhelekileyo, phambi kwamaqabunga, izakhamuzi zasehlobo zikhawuleza ukusasaza umgquba omtsha emhlabeni. Kodwa le ndlela ayinikezeli iziphumo ozilindeleyo. Kungenzeka ukuba iinkqubo zokubola eziphazamisa ukulahleka kwe-oxygen ziya kuqala. Ngenxa yoko, iingcambu zonakalisiwe, ezisebenza njengentlanzi kwiintlobo ezinambuzane.
- Kwixesha lekwindla, ukukhula kwezityalo kuphelile , ngoko ke izondlo ezininzi azidingeki. Xa ulungiselela umhlaba ubusika, ukutyiswa kuphelile. Inkuthalo yonke iya kuhamba ngamanzi angaphantsi komhlaba kunye namanzi angaphezulu. Ngokukhawuleza emva kokuvuna, ungatshala isaladi yentsimi, i-Persian clover. Kungcono ukulungiselela umhlaba ubusika ngale ndlela, kuba ezi zityalo ziphucula isakhiwo sayo kwaye zikhusela ukuguguleka. Inyaniso yokuba iingcambu ze-clover zezimbali okanye ubhontshisi zifana nokulungisa i-bacteria nodule. Bayakwazi ukufanisa i-nitrojeni emoyeni. Ngaloo ndlela, izitshalo eziluhlaza ziza kunceda ukuphucula umhlaba ngomoya. Aba bancedisi baya kuba nako ukwenza umsebenzi wabo entwasahlobo ngaphambi kokutyala.
- Ukulungiselela umhlaba ubusika. Kubalulekile ukukhusela umhlaba kwimiphumo yemozulu. Emva kwemvula enamandla, kuba nzima, ukukhahlela, okunciphisa umphumo wezinto eziphilayo zomhlaba. Kubalulekile ukulungisa umhlaba wokubhakabhaka ebusika, kuba oku kwenza ukuba kunokwenzeka ukuphepha iingxaki kwixesha elizayo. Iqabunga, amaqabunga aweleyo, aguba umhlaba, avule aze enze i-humus. Oku kuncedisa ekukhuphukeni okuncinci kwamanzi, ukuphazamisa ukukhula kokhula, kukhuthaza umsebenzi obalulekileyo wabemi bomhlaba.
Zonke ezi zixhobo azivumeli ukuba umhlaba uwile, yenze ukhululeke, uphucule umgangatho womoya. - Ukulungiselela umhlaba ubusika. Kungekudala, iingcali zafika kwisigqibo sokuba ukumbumba kwekwindla kubangela ukuphazamiseka kwesakhiwo somhlaba. Umba wukuthi zonke izinto zehlabathi zikhetha ihlwempu yomhlaba e-oksijeni, ngoko yanele ngokwaneleyo ukutsala intsimi kuphela entwasahlobo. Kwaye ngaphambi kokuba ubusika nje ukhulule umhlaba kunye nemifoloko. Lo mgaqo unomzekelo omnye kuphela: umdongwe womhlaba.
