Ukusabalalisa umanyolo wendabuko kubangela ukulahlekelwa okukhulu kwezakhamzimba. Ngaphezu kwalokho, amanani kamanyolo ayakhuphuka ngenxa yezindleko eziphezulu zamandla. Izinto ezithatha indawo ye-nitrogen ezivela kuma-air scrubbers amakhemikhali kanye nokugxila kwamaminerali ziyizindlela eziwusizo, ngokusho kokuhlolwa okuningi okusebenzayo.
Phakathi ku uchungechunge lwama-webinars , iNetherlands Center for the Development of Circular Precision Fertilization (NCOK) kanye ne-Agrivaknet banikeza abalimi, abalimi bezitshalo kanye nabalimi ulwazi mayelana nokusetshenziswa kwezithasiselo zomanyolo.
'Siyasabela esivumelwaneni sobumbano, esifuna ukunciphisa ukukhishwa kwe-nitrogen ne-ammonia kanye nokuthuthukisa ikhwalithi yenhlabathi kanye nokuhlukahluka kwezinto eziphilayo'. Kusho uNoud Janssen, ohola ama-webinar. 'Ngokusebenzisa izithasiselo zomanyolo, singafinyelela ukukhishwa okuphansi okufika kumaphesenti angamashumi amane; futhi sithuthukise imodeli yemali engenayo yabalimi kanye nabalimi bezitshalo.'
I-Renure-N
Ukukhululwa kwesikhashana manje kusebenza ezitshalweni eziningi zokufaka umanyolo esikhundleni sazo. Kulindeleke ukuthi lokhu kuzovunyelwa kuwo wonke umuntu ngaphansi kwegama elithi Renure-N ngesishayamthetho saseYurophu kulo nyaka. Igama elithi Renure lisho ukusetshenziswa kabusha kwe-nitrogen evela emqubeni. Lokhu kunikeza abalimi nabalimi bezitshalo isikhala esengeziwe sokubeka imikhiqizo yomquba wezilwane. Ngakho-ke konge izindleko zokucubungula umquba noma ukuthengwa komquba. Bangaletha nezinto eziphilayo eziningi ezweni, okuthuthukisa ukuvunda kwenhlabathi.
Kunezinto eziningi ezintsha ezenzekayo mayelana nokukhiqizwa komanyolo othatha indawo. Isibonelo, i-nitrogen ingakhishwa engxenyeni yoketshezi oluwuketshezi lomanyolo, oluwusizo emhlabathini. Esibayeni, umanyolo nomchamo kuqala kugcinwa ngokwehlukana. Intuthuko yezobuchwepheshe ivumela futhi i-ammonia engaphezulu komanyolo ukuthi ikhishwe futhi iguqulwe ibe umanyolo. Lokhu kuphumela ekunciphiseni okukhulu kwe-ammonia.
I-Joint Quest
Ukusetshenziswa kahle komanyolo omusha akugcini nje ngokuthuthukisa ikhwalithi yomhlabathi, kodwa futhi kuthuthukisa ikhwalithi yamanzi angaphezulu ngoba i-nitrate encane iyakhishwa. Ekufuneni ukukhishwa okuphansi komoya, abalimi kanye nabalimi bezitshalo basebenzisana nabacwaningi kanye nabeluleki kanye nohulumeni.
Uma kukhulunywa ngokudonswa kwama-nitrate emanzini angaphezulu, ukugxila kuvame ukuba ezitshalweni ezibanzi zangaphandle njengokutshala imifino evulekile kanye nokutshala izithelo. Ukulahlekelwa yi-nitrate emanzini angaphezulu kuphezulu kakhulu enhlabathini enesihlabathi neyomile eningizimu.
Umanyolo oqondile
Ukusebenzisa umanyolo ngendlela ewuketshezi kuyingxenye yesisombululo, kusho uWim de Hoop we-Knowledge Center for Green Growth kwenye yezingxoxo ze-webinar. 'Ngokufaka umanyolo onembile nokwandisa okuqukethwe kwezinto eziphilayo, ubulala izinyoni ezimbili ngetshe elilodwa. Uvimbela ukukhishwa kwegesi, kodwa futhi ungandisa ukuvunda kwenhlabathi.'
Esinye sezinto ezithatha indawo kamanyolo amanzi okukhipha umanyolo, umkhiqizo osele ovela ezindaweni zokuhlanza umoya emapulazini ezingulube. I-ejensi yocwaningo iDelphy ihlole ukusetshenziswa kukamanyolo ekutshalweni kwezithelo ocwaningweni lweminyaka emithathu. Amanzi okukhipha umanyolo abonakala efana nomanyolo. Isibonelo, azikho izinguquko noma umehluko esitokweni somhlabathi, kokuqukethwe kwezakhamzimba emaqabunga noma izithelo, kodwa futhi akukho mehluko ngobukhulu bezithelo noma okuqukethwe ushukela noma esivunweni sonke.
Ibhalansi Yendwangu Ephendulayo
Ukuze kulinganiswe ibhalansi yezimbiwa emapulazini, ikhabhinethi isebenza ekusunguleni i-Afaccountable Substances Balance. IKomidi le-Remkes selivele liphikisana kakhulu ngalokhu ekwelulekeni kwalo ngenkinga ye-nitrogen.
Umqondo uwukuthi abalimi kanye nabalimi bezitshalo bangazinqumela bona ukuthi yiziphi izinyathelo ezizothathwa ukuze kuncishiswe ukukhishwa kwegesi. Ngakho-ke kuzothatha indawo yemithethonqubo yamanje yemithi futhi kufane nomthetho we-MINAS owawusebenza kuze kube sekuqaleni kwaleli khulu leminyaka.
Njengesibonelo sendlela i-Accountable Substances Balance engasebenza ngayo ngokoqobo, uhulumeni ubheke ukucaciswa okwengeziwe kwe-Recycling Guide ekulimeni ubisi. Lokhu ukubhaliswa okuhlanganisiwe kokugeleza kokudla kanye nomanyolo epulazini.
