  Indlela Yokutshala Nokuvuna Ukolweni: Umhlahlandlela Ophelele Wokuvuna Okuphumelelayo

Ukukhethwa komanyolo ofanele kanye nenhlanganisela yawo kufanele kusekelwe ekuthunjweni kwenhlabathi kanye ne-pH, okuqukethwe kwezinto eziphilayo, izimo zezulu, umlando wangaphambili wokutshala, kanye nesivuno esihlosiwe.

Ukuhlaziya umhlabathi: isinyathelo esibalulekile sokuvundisa ngempumelelo

Ngaphambi kokunquma ngohlobo lukamanyolo kanye nenani lawo, kubalulekile ukwenza a ukuhlaziywa kwenhlabathiLokhu kuxilongwa kunikeza ulwazi oluningiliziwe mayelana:

• Ukutholakala kwangempela kwezakhi eziyinhloko (N, P, K) kanye nezakhi zesibili (S, Mg, Ca).
• Ukuba khona kwama-micronutrients kanye nokushoda okungenzeka (Zn, B, Fe, Cu, manganese).
• Izinga le-pH, ukuthungwa kanye nokuqukethwe kwezinto eziphilayo.
• Amazinga osawoti, isilinganiso se-C/N neminye imingcele ebalulekile ukuze kuthuthukiswe isu lokuvundisa.

Ngale datha, uchwepheshe wezolimo angakwazi ukulungisa isilinganiso esiqondile kanye nokwakheka kukamanyolo, agweme kokubili ukusilela kanye nokweqisa okungabangela ukulahlekelwa kwezomnotho noma ukulimala kwemvelo. Ukuze uthole imininingwane eyengeziwe, bheka yethu Umhlahlandlela ophelele wokutshala ukolweni ekhaya.

Ukuhlaziywa kufanele kuphindwe ngezikhathi ezithile, njengoba ukushintshwa kwezitshalo, isimo sezulu, kanye nezinqubo zokuphatha kushintsha ukuvunda komhlabathi ngezikhathi ezithile zonyaka.

Imithethonqubo yokufakwa kukamanyolo namasu kakolweni

Uhlelo oluyimpumelelo lokuvundisa lubheka kokubili uhlobo nomthamo, kanye ne isikhathi esifanele kakhulu sokufaka isiceloIzinhlobo eziyinhloko zomanyolo ngokuya ngomjikelezo kakolweni yilezi:

• Umanyolo wangemuva: Isetshenziswa ngaphambi kokutshala, inikeza inani eliphelele le-phosphorus ne-potassium edingekayo, kanye nengxenye ye-nitrogen edingekayo. Kuyisihluthulelo sokuqinisekisa ukuthuthukiswa okufanele kwasekuqaleni, ukwakheka kwezimpande, nokumuncwa kwezakhi okuphumelelayo.
• Ukugqoka okuphezulu: Iqukethe ukusetshenziswa kwenayithrojeni ngokwengxenye ngemva kokumila nangesikhathi sokutshala kanye nokukhula kwezitshalo. Ivumela imithamo ukuthi ilungiswe ngokwezinga lokumuncwa kwesitshalo futhi inciphise ukulahlekelwa.
• Ukukhulelwa kwe-Foliar: Inikeza izakhamzimba ezifana ne-nitrogen, i-potassium, kanye nama-micronutrients ngqo emaqabunga ngokufafaza. Ukwelapha okuhambisanayo, okuwusizo ikakhulukazi ngezikhathi ezibucayi njengokumila kwezindlebe, ukugcwaliswa okusanhlamvu, noma izimo ezicindezelayo.

Ukuze uthole ulwazi olwengeziwe ngezinyathelo ezibalulekile zokuphatha ukolweni, vakashela yethu.

Kuyancomeka ukuthi izicelo zesikhala zihlangabezane nezidingo ezinyathelweni ezibalulekile: ukusuka ekuhlahleni kuze kufike ekuveleni kweqabunga lefulegi (iqabunga lokugcina ngaphambi kokuvuthwa), lapho kusetshenziswa kufika ku-85% wenitrogen ne-phosphorus edingekayo. I-Potassium ibaluleke nakakhulu ngesikhathi sokugcwalisa okusanhlamvu.

Ukuphatha ngendlela efanele kuhlanganisa ukuhlukaniswa kwe-nitrogen (ikakhulukazi enhlabathini enesihlabathi noma eniselwayo), ukusebenzisa i-phosphorus njengesisekelo sokugqoka, kanye nokulungisa i-potassium ngokuvumelana nenhlabathi kanye nezilinganiso ezikhishwe.

Ngaphezu kwalokho, ama-micronutrients afana ne-zinc ne-boron kufanele asetshenziswe ngezikhathi zomzimba lapho umsebenzi wawo ubalulekile. Isibonelo, i-zinc ngesikhathi sokutshala kanye ne-boron ngaphambi kokuqhakaza.

Izilinganiso zokukhishwa kanye nezidingo zokudla okunomsoco wezitshalo zikakolweni

Inani lemisoco ekhishwa ukolweni enhlabathini liyahlukahluka kuye ngesivuno esilindelekile nezimo zemvelo, kodwa njengereferensi evamile, kuwo wonke amakhilogremu ayi-1.000 wokusanhlamvu akhiqizwayo (kuhlanganise ne-biomass yezitshalo), okulandelayo kuyadingeka:

• 30 kg we-nitrogen (N)
• 12 kg we-phosphorus (P₂O₅)
• 28 kg we-potassium (K₂O)
• 5-7 kg we-calcium oxide (CaO)
• 3,5-5 kg we-magnesium oxide (MgO)
• 5,2 kg isulfure (S)

Ngokucatshangelwa la magugu kanye nokuvunda komhlabathi kokuqala, umthamo oqondile kanye nohlobo lukamanyolo oluzosetshenziswa lunganqunywa. Izinhlobo zikakolweni ezintsha, ezikhiqiza kakhulu zingase zibe nezidingo eziphakeme kwezinye izakhamzimba futhi zizwele kakhulu ekuntulekeni kwe-micronutrient.

Izinto ezithinta isivuno sikakolweni kanye nekhwalithi

Isivuno sikakolweni kanye nekhwalithi akuncikile kuphela kumanyolo, kodwa futhi nasezintweni eziningana ezihlobene ze-agronomic:

• Inombolo yamathila imitha yesikwele ngayinye: Inani eliphakeme leziqu zesibili linyusa inani lezindlebe ezikhiqizayo.
• Inani lama-spikes ngesitshalo ngasinye: Uma likhulu inani, likhulu amandla okukhiqiza ngeyunithi ngayinye yendawo.
• Inombolo yezinhlamvu endlebeni ngayinye nesisindo somuntu ngamunye: Lezi zingxenye ezimbili zinquma ngokuqondile ukusebenza futhi zingathuthukiswa ngokuthi a ukudla okunomsoco.
• Impilo yezitshalo: Ukulawulwa okudidiyelwe kwezinambuzane nezifo kubalulekile ukuze kuvinjelwe ukulahlekelwa futhi kwandiswe ikhwalithi.
• Okuqukethwe kwamaprotheni okusanhlamvu: Amanani aphezulu amaprotheni ahlobene nekhwalithi yokubhaka kanye nenani lezohwebo likakolweni.

Ukufakwa komanyolo wekhwalithi kanye nokusetshenziswa kwezindlela ezingcono kakhulu zokuphatha ukudla okunomsoco kuvumela abalimi ukuthi bangagcini nje ngokukhulisa ukukhiqiza kukakolweni, kodwa futhi nokwenza ngcono inzuzo kanye nokugcina impilo yomhlabathi kanye ne-ecosystem yezolimo. Inkambu ngayinye nezinhlobonhlobo zingadinga iphrothokholi ethile, ngakho-ke ukusekelwa kobuchwepheshe nezibuyekezo eziqhubekayo kubalulekile.
