I-ERA iyizakhi zesine ezibaluleke kakhulu ekukhiqizweni kukakolweni ngemuva kwe-nitrogen, phosphorus ne-potassium. Phambilini, izitshalo zazikhululekile ukuletha isibabule emasimini ngokusebenzisa izimvula ezingcolisiwe, kodwa njengoba izingxenye zokuthuthwa zendle zithuthukisa inani lesibabule elahliwe ngezimvula, zehla kakhulu. Futhi abase-Agrarians kufanele bakhiphe umanyolo ngomanyolo, ngoba uma kungenjalo isivuno sesiko singancipha, sitshele uBill Spiegel endabeni yakhe kwi-portal www.agrictulture.com.
Ukuntuleka kwesibalfur ezitshalweni zikakolweni kubukeka kanjena.
"Njengomthetho, ukolweni nokuntuleka kwesibabule kuphuzi futhi kwehlisiwe futhi kuyabonakala emikhakheni yensimu, lapho ukucekelwa phansi kwenhlabathi bekulokhu khona, - kuchaza uDorivar Ruis u-Diaz, uchwepheshe wenhlabathi uchwepheshe wase-University of Kansas. - Ungabona izindawo ezinokuntuleka kwesibabule eziqongweni zamagquma noma emithambekeni lapho ukuguguleka kwenzeka khona futhi okuqukethwe kwezinto eziphilayo kwehla. Noma ukolweni ezindaweni lapho kususwe khona ungqimba olungenhla lwenhlabathi noma ukusikeka kwenziwa - ngokwesibonelo, amasimu anezinwele noma aqondanisiwe - ukolweni olwaluhlwawe kungenzeka kube nezimpawu. "
"Qaphela: Ukuntuleka kokuqina kwezilimo kuvame ukuba kubi ngokuswela i-nitrogen (n). Kodwa-ke, ngokungafani nokushoda kwe-nitrogen, lapho amaqabunga amadala "avuthayo" futhi aphuzi, ngokushoda kwesibabule, izimpawu eziphuzi eziphuzi zivame ukuvela kuqala ezinhlamvu eziphezulu. Izitshalo zikakolweni ezinokuntuleka kwama-s ekugcineni ziba chlorobic, "kuchaza i-RUIZ Diaz.
Ukushoda kwesibabule kukolweni kuyabonakala kusenesikhathi entwasahlobo, ngaphambi kokuba ama-organic s amaminerali avela entweni yenhlabathi, futhi ngaphambi kokuba izimpande zikakolweni zingakhula zijule ekusetshenzisweni kwanoma yiluphi uSala ama-SALAS S (sulfate).
"Ukuntuleka kwesibabule kuvame ukuba nzima ukukhomba, ngoba i-chlorosis ayibonakali ngaso sonke isikhathi," kusho uRuiz Daiz. - Amasiko ngokuntuleka kwesibabule kungenzeka futhi aphansi, amancanyana futhi abunjiwe. Endabeni kakolweni nezinye izilimo zokusanhlamvu, ukuvuthwa kubambezeleka. Umncintiswano wonyaka wobusika okhula ukhula nawo uqiniswa ngenxa yokukhula okuhamba kancane kanye nokuntuleka kobuqili obuhle. "
Uma emlandweni wensimu kuvele kusethi isethi yokushoda kwe-sulfur, abalimi bangabheka ukusetshenziswa kwe-S njengendlela yokuvimbela ebusika.
Imiphi imikhiqizo empunga engasetshenziswa
Kunamanyolo amaningi aqukethe ama-s-equkethe kahle ekwenzeni izikhathi ezithile futhi aqede ukusilela kwesisulu:
I-Ammonium Sulfate iyisitatimende esomile esingumthombo wazo zombili i-nitrogen no-S. Noma kunjalo, inekhono eliphakeme le-acid, futhi i-PH kufanele ibhekwe. I-Ammonium sulfate isho izinketho ezinhle zokudilizwa kwangaphambi kokuhlwanyela noma ukondla ukulungisa i-sulfur Deficit ekhona.
I-Gypsum i-calcium sulfate futhi imvamisa itholakala kwifomu elinama-hydrate aqukethe ama-18.6% s, futhi kuma-granule, okuvumela ukuthi uwaxube nezinye izinto. Njengoba lo ngumthombo we-sulfate, izotholakala ngokushesha futhi ilungele ukondliwa kwentwasahlobo. Kodwa-ke, i-gypsum ayincibiliki kangako emanzini umanyolo amaningi, kufaka phakathi i-ammonium sulfate.
Imikhiqizo emisha ye-NPS, efana nemicrosressionals nabanye, yizinto zokwakha ezivela kwi-ammonium phosphate, okubandakanya ama-s, futhi kwezinye izimo ezinjalo ezincane ezincane njenge-zinc. Eminingi le mikhiqizo, ikhona ngesimo senhlanganisela ye-s okuyisisekelo ne-sulfate.
I-Ammonium Thiosulfate ingumkhiqizo osuselwa kakhulu we-S-equkethe ukukhiqizwa komanyolo owuketshezi, ngoba iyahambelana ne-nitrogen solutions neminye imikhiqizo eqediwe yotshwala. Ilungele ukondliwa kwentwasahlobo.
I-Potassium Thiosulfate ingumkhiqizo okhanyayo, ingahlanganiswa nolunye umanyolo owuketshezi. Njenge-thiosulfate, efanelekile ukondla ngaphambi kwesikhathi entwasahlobo.
Njengomsoco wesine obaluleke kakhulu, isibabule edlala indima ebalulekile ekwakhekeni kwama-amino acid, amaprotheni namafutha futhi kubalulekile ukwakheka kwe-chlorophyll.
I-nitrogen kanye nesibabule kuhlotshaniswa nezinga elithile, ngoba i-sulfur idlala indima ekusebenzeni kwe-nitratrestundase enzyme, esiza ukuguqula ama-nitrate kuma-amino acid. Ngenxa yalokho, ukusebenza kahle kokusetshenziswa kwe-nitrogen kungancipha ngokuntuleka kwesibabule, kusho uRuis Diaz.
