Inhlabathi ukungcoliswa

Soil - iyona ungqimba phezulu inhlabathi, esibonakala wenzalo - ikhono ukondla ezikhulileyo futhi ukukhuthaza nokuvuthwa yabo. Ezolimo akunakwenzeka ngaphandle kwenhlabathi, ngoba Simila amasiko amaningi asetshenziswa ukulungiselela ukudla umuntu futhi emfuyo okuphakelayo. Vele indlela ewusizo nokunomsoco kukhona mikhiqizo incike izinga futhi isimo kwenhlabathi, isuka ekunakekelweni wakhe, ukusuthisa futhi ayakhala.

ngempumelelo kakhulu wezolimo ezibhekwa black onothile in humus (humus). Pedogenesis - inqubo eside futhi eziyinkimbinkimbi, okuyinto umphumela ukuchayeka umoya-mpilo ukuze umzali idwala ekuqongeleleni ukubola izinto eziphilayo. Uma kukhona ngisho ukungcoliswa kancane emhlabathini, kungaba zibuyiswe isikhathi eside. Ngakho-ke, kumelwe ngokucophelela futhi unakekele kahle umhlaba.

Phakathi naleso sikhathi, umhlaba wokulima ngenxa yokuntuleka ukunakekela kwakhe kancane kancane balahlekelwa wenzalo encishisiwe ngokushesha inani humus. Indoda efuna ukuthola enhlabathini ngangokunokwenzeka, ngaphandle kucatshangelwa isidingo kungase kutholakale alternation izitshalo kwesinye isiza, igama elithi "ukuphumula" yasendle ngemva kwenkathi ethile "umsebenzi".

Ukungcoliswa ukuguguleka kwenhlabathi kungenzeka hhayi umonakalo owenziwe abantu, futhi i-unomphela imiphumela elimazayo umoya namanzi. Ngokuvamile, ukuguguleka kwenhlabathi kula mashumi eminyaka amuva uyekile kube inkinga yokusekela zokulima futhi atholwe izinga izinkinga zemvelo.

ukwelashwa amaningi kubangela ukungcola inhlabathi. Kwaphela iminyaka eminingi phezu kwezwe elifanayo ngezikhathi sikhule isiko ezahlukene, ngaphandle kokwenza phansi ukuthi unika. Ngakho-ke akuyona ilungelo ukuthi inhlabathi iphelile futhi asisakwazi ukwenza ngokugcwele imisebenzi yabo - izitshalo supply sondleke, ukuhlunga imfucuza namanzi yemvelo.

Ukuze umhlabathi kudingeka ngokwesayensi futhi enomqondo asondele ungagcina eside ukusetshenziswa kwalo futhi kulinywe ukuze uthuthukise wenzalo ukuphuma ke ukudla ihlanzekile futhi inempilo. Ukuze wenze lokhu, kumele uthobele kwezitshalo, sebenzisa impumelelo eziphambili yesayensi, lula futhi esebenza kahle ipulazi imishini, ngangokusemandleni ukusebenzisa amakhemikhali, bese besebenzisa amanye izindlela zokulima yemvelo

umquba wamakhemikhali nezibulala-ikakhulukazi nitrate - umthombo enkulu ukungcola inhlabathi. Ngamandla abo, lezi izinto akuzona eziyingozi futhi angeke abe umthombo ubuthi, kunalokho - izitshalo ukuzisebenzisa ukuhlela amaseli, asinayo i-chlorophyll kumiswa. Nokho, baba emhlabathini, nitrate ungene ukudla, bese - emzimbeni womuntu. Kukhona ama-nitrate nama jikisa nitrites futsi bangene yokusabela chemical ahlanganisa igazi - hemoglobin. Kule methemoglobinemia ekuthuthukiseni - isifo kabani izimpawu ziyabonakala ukwehla ingcindezi, ukushintsha shades of nolwelwesi lwamafinyila kanye isikhumba, ukwakheka isifo senhliziyo noma yamaphaphu.

Okunye futhi okubaluleke ngokufanayo ukungcola uwoyela kwenhlabathi. Kuyinto kakhulu eduze emendweni, amagalaji, amagalaji, imoto amapaki. Futhi ngalezo zindawo lapho kokuba umkhiqizo kawoyela, ukucutshungulwa yayo, ezokuthutha, ukungcola inhlabathi uwoyela ezingeni idlula ngokuphindwe kayishumi ovumelekile.

Izinhlelo imfucuza landfill sites ezahlukene umsuka kuholela ukusetshenziswa kahle komhlaba, zingase zibe nemiphumela ukungcola emkhathini, amanzi, okwandisa zokuthutha izindleko futhi Yebo ukulahlekelwa engelapheki amaminerali ezibalulekile enhlabathini.
