Ososayensi bavame ukungena ezindleleni zokukhula kwezitshalo, ngoba namuhla imboni yamakhemikhali isebenza eduze ne-agrosphere. Mhlawumbe, umqondo olula wensimu uqobo "okhulayo ukhukhamba ngobuchwepheshe beDashi" uzohlanganiswa namazinga wehhashi omanyolo nawo wonke izithako ezilimazayo. Akuwona lutho ngoba ebusika ungathola isivuno esinjalo. Ngenhlanhla, ubuchwepheshe bokukhukhamba okukhulayo ebusweni obubamba ebusika buxhunyaniswe nesistimu ngokusebenzisa umanyolo, kodwa hhayi ngobuningi bawo.
Yiziphi izimo zokukhukhamba ukhukhamba ebusika?
Okokuqala, ukuze siphumelele umcimbi wonke, sikhetha ukhukhamba ukukhula ebusika, ukubekezela emthunzini, izinhlobo ezikhethekile ezakhiwe nge- hothouse. Kodwa lokhu kuyingxenye yendaba kuphela, iphuzu eliphelele lilinganiselwe futhi kulandelana kokungeziwe.
Ubuchwepheshe beDutch bokukhukhamba ukhukhamba ebamba lokushisa ebusika akusho ukukhulelwa ngokweqile, ngoba lokhu kuyoholela ekutheni umhlabathi ushubile. Lapha, ukulungiswa nokuvumelana, kanye nokukhetha okusemandleni kwenhlabathi, kubalulekile:
- Ukuze ukhule, udinga inhlabathi evulekile kakhulu, kanye nomsele olungiselelwe kahle. Kubalulekile ukuthi inhlabathi igcwele izakhi. Ekwindla, ekugcineni, cishe ingxenye engama-tani yomquba ulethwa kule ndawo. Inani elikhulu lizoholela ekwenzeni i-salinization yenhlabathi, uhlelo lokusebenza entwasahlobo lungashisa izimpande zezitshalo.
- Okubalulekile ebuchwepheni baseDutch bokukhukhamba okukhulayo ebusweni bokushisa ebusika ukukhetha indawo. Akunconywa emva kokuvuna ukubeka imibhede endaweni efanayo nangenkathi ezayo. Ngemuva kweminyaka emine kuphela kuvunyelwe ukuyisebenzisa kabusha. Uma kungenjalo, uzothola inkinga yokubola omnyama wezimpande zezitshalo.
- Ukuhlakulela kwamakhukhamba ngokusho kobuchwepheshe beDutch kuhilela ukwethulwa kwazo zonke izakhi kuphela ngendlela yokudonsa. Phakathi nesikhathi sonke semifino kuyadingeka ukondla ukutshala nge nitrogen. Emhlabathini ngokwawo sengeza u-800 gr, bese u-500 gr indlela yokunisela. Emhlabathini, sengeza isithasiselo entwasahlobo, okunye emva kokuvuna isitshalo sokuqala njalo ngemva kwamasonto amabili.
- Ngokusho kobuchwepheshe bekhukhamba ezikhulayo endaweni yokushisa ebusika, ngaphambi kokutshala, 2.5 kg we-phosphorus kufanele ifakwe enhlabathini.
- I-potassium isetshenziswe kilogram ngaphambi kokutshala bese emva kokuhluma. Kubalulekile ukuthi umanyolo awunayo i-chlorine, echaphazela kakhulu ukhukhamba.
- Ungakhohlwa ukwakha ne-magnesium inani lemali. Lokhu ngeke kuvumele amahlamvu ukuba aphuzi futhi aphumele.
