Ucwaningo Luthola Ukuguquka Kwesimo Sezulu Kungashintsha Ngokuphawulekayo Indawo Yokuphila Yezintaba Ezintekeme

Intaba

Izifunda ezinezintaba zeplanethi yilezi ngaphansi kosongo oluqondile lokuguquka kwesimo sezulu okubangelwa ngabantu abangaguqula ngokuphelele lezi zindawo ezintekenteke, ngokusho kwethimba labaphenyi bamazwe omhlaba, kubandakanya nochwepheshe wase-University of Manchester.

Isazi semvelo kanye noprofesa uRichard Bardgett, obeyingxenye yethimba lamazwe omhlaba eliqale futhi lakha lolu cwaningo, uthe banalo uthole umlayezo ocacile ukuthi ukuguquka kwesimo sezulu kungashintsha izakhiwo ezibaluleke kakhulu zemvelo yezintaba futhi kungadala ukungalingani phakathi kwezitshalo nomhlabathi ezindaweni eziphakeme zezintaba.

Ucwaningo lwamazwe omhlaba, olwaqhubeka izifunda eziyisikhombisa zezintaba ezinkulu kakhulu emhlabeni, kuveze ukuthi ukukhuphuka kokuphakama okubikezelwayo kuyinkomba yokuguquka kwesimo sezulu futhi kukhuphule njalo ukutholakala kwe-nitrogen emhlabathini ekukhuleni kwezitshalo, okusho ukuthi ukuguquka kwesimo sezulu kungaphazamisa indlela esebenza ngayo imvelo yezintaba.

Kutholakale ukuthi plant phosphorus ukutholakala wawungalawulwa ukuphakama, futhi ngenxa yalokho ibhalansi ye-nitrogen ne-phosphorus ezitshalweni ishiya indawo evamile ezindaweni eziyisikhombisa ezifundwe ezindaweni eziphakeme. Lokhu kusho ukuthi ukunyuka kwamazinga okushisa kungaphazamisa ibhalansi ebalulekile phakathi kwalezo zakhi zomzimba ezisekela ukukhula kwezitshalo futhi zingaguqulwa ngokuphelele ezindaweni eziphakeme zezintaba.

Kutholakale nokuthi ukwanda kwe- amazinga okushisa nemiphumela yawo ukuthola umsoco zezitshalo zazixhunyaniswe nezinye izinguquko emhlabathini, kufaka phakathi inani lezinto eziphilayo kanye nokwakheka komphakathi wezinambuzane zomhlaba.

UProfesa Bardgett uthi:

Izindawo ezisezintabeni amboze ngaphezulu kobuso beplanethi futhi basengozini enkulu ekushintsheni kwesimo sezulu. Imiphumela yethu, eza ngemuva kocwaningo olunzulu lwama-gradients ekukhuphukeni kwezifunda eziyisikhombisa zezintaba zomhlaba, kufaka phakathi iJapan, iBritish Columbia, iNew Zealand, iPatagonia, iColorado, i-Australia, neYurophu, iphakamisa ukuthi ushintsho lwesikhathi esizayo Ukuguquka kwesimo sezulu kuzoguqula indlela lezi ukusebenza kwemvelo.
