Imvundisi ezenziwe ngaphandle kwamakhemikhali zifakwa ehlabathini zimagiqana. Imvundisi ezenziwe ngaphandle kwamakhemikhali zikhipha izakhimzimba kancanikancani njeke kufanele zifakwe endaweni ekutjalwa kiyo ngaphambi kokobana kutjalwe. Lokhu kuzokukhandela ukutlhogeka kwezakhimzimba estjalweni nanyana eentjalweni ezisakhulako.
Ikhompowusti: Ikhompowusti ngilokhu okwenzeka lokha i-organic material ihlanganiswa beyivunyelwe kobana ibole.
Umanyoro: Umanyoro bulwongwe beenlwane eziphilako obubuthwa ehlabathini ukugcugcuzela ukwenzeka kwenunwana.
Iimvundisi Ezenyiwe Ngamakhemikhali
Iimvundisi ezenyiwe ngamakhemikhali ngezenziwe babantu lapha bahlanganise khona izinto ezifileko, kanye neembaseli nezenziwe ngesilinganiso esitlhogwa zintjalo ezehlukahlukeneko ebujameni ebuthize. Iimvundisi ezenziwe ngekhemikhali zisebenza mzinya kunalezo ezanziwe ngaphandle kwawo begodu zibakhona estjalweni ngemva kokobana zifakwe.Zivamise ukufakwa zimaqana nanyana zimamanzi. Lokha nazisetjenziswa khulu iimvundisi ezenziwe ngamakhemikhali nalezo ezinziwe ngaphandle kwawo kungarholela ekwakhekeni kwetswayi nokuphunguka kwama-gciwani ehlabathini, okungabanga i-leaching ehlabathini.
Lokhu kungalatjhwa ngokufaka i-organic material efana nekhompowusti kanye nomanyoro zibuyiselwe ehlabathini nangokutjala nokukhulisa iintjalo ezivala ihlabathi ezihlaza ezifana namadlelo, i- rye kanye ne-oats nokuzitjala ehlabathini.
Amanothi
Ukusebenzisa ihlanganisela yemihlobo emibili yemvundisi kuletha inzuzo ngombana lokhu kusebenzisa amandla wazo zombili ukulungisa lapha esinye sibhalelwa khona. Iimvundisi ezenziwe ngaphandle kwamkhemikhalu zivikela bezenze bona ihlabathi ihlale inepilo ngokwemvelo lezo ezenziwe ngamakhemikhalu ziletha izakhimzimba msinya kanye nezekhimzimba ekungizo estjalweni.
