Kunzima ukugcizelela indima ye-potassium umquba wokulima kanye nokulima. Kungani badinga umquba we-potassium? Izitshalo zensimu, zisetshenziselwa ukwandisa isivuno nokumelana namazinga okushisa aphansi. Inani elanele le-potassium linikeza ukwandisa kokumelana nesomiso kwezitshalo, kwenza izithelo zibe lula ekugcineni kwesibusika. Kulawo utamatisi, okwezwela kakhulu ngokuntuleka kwe-potassium, angeke uvuthwe futhi ahlale eyingxenye eluhlaza yesithelo esiseduze nesiqu.
Yiziphi umquba womanyolo okhona?
Ukwakhiwa kwamanyolo we-potassium kubenza bahluke komunye nomunye. Qhathanisa umquba oqukethe i-chlorine futhi ngaphandle kwawo. Ukuba khona kwe-chlorine kuhlukile ezinhlobonhlobo ezahlukene zemanyolo futhi kuhluka ngamaphesenti. Ngakho-ke, okuqukethwe okuphezulu kakhulu kwe-chlorine ku-potassium chloride kufinyelele ku-60%, bese i-potassium sulfate ikhuphuka ku-52%, futhi okuqukethwe okungenani kloride kumanyolo we-potassium womanyolo ku-40%.
Njengoba i-chlorine ingumuthi onamandla futhi ingathinta isitshalo, umanyolo onokuqukethwe akusetshenziswanga ngesikhathi sehlobo sasehlobo. Lesi sigaba somanyolo sitholwa enhlabathini ekwindla sekwephuzile, ngakho-ke ngesikhathi se-chlorine ebusika igezwa ngamanzi emvula futhi ayilimazi izitshalo. I-chlorine inomthelela kakhulu eSolanaceae - amazambane, i-pepper ne-tomato, ngakho-ke kubalulekile ukuba bakhethe umanyolo ongenawo i-chlorine.
Ungakhohlwa ukuthi ukusetshenziswa okuvamile kwama-chlorine okuqukethe umanyolo kuholela ekwenzeni i-acidification yomhlabathi kusayithi. Ukuvimbela lokhu kungenzeki, ngokushesha ngaphambi kokuba umanyolo wengeziwe, i-lime yenezelwa kuyo ukuze i-neutralization.
Umquba omuncu
Amakhomikhali e-Phosphoric-potash ne-nitrogen-potassium ayingxenye yezimo eziyinkimbinkimbi zemifuno. Izicelo zazo eziningi zibenza zidume kakhulu phakathi kwalabo abazihlakulela ngokuzimela izitshalo zasegadini. Ngakho-ke, isibonelo, i- potassium nitrate , eye yaziwa isikhathi eside kuwo wonke ama-fertilizer, ngokuqukethwe kwe-nitrogen yi-fertilizer engcono kakhulu yokugcina izithombo zokugcina izithombo. Umanyolo ongcono kakhulu we-phosphorus-potassium yi-superphosphate. Ihlakazeka kahle futhi ingasetshenziswa kulo lonke ihlobo.
Umanyolo we-potassium-magnesium - i-calimagnesium inikeza umphumela omuhle emhlabathini onesihlabathi lapho ezinye izinhlobo zingase zingasebenzi.
Umanyolo ovame kakhulu owaziwa ugogo wethu umlotha - futhi umanyolo we-potash. Ngaphezu kwe-potassium, umlotha uqukethe i-magnesium, i-phosphorus, insimbi, ithusi kanye nabanye. Umlotha ungenziwa kungakhathaliseki ukuthi unjani. Ebusika, yanezelwa ngaphambi kokumba umhlaba, futhi ehlobo umlotha usetshenziselwa ukugqoka phezulu kokubili ngendlela eyomile neyomile.
I-ash inezinhlobo ezahlukene zokusetshenziswa - amajikijolo, izihlahla, amazambane kanye nemifino yezimpande. Ngenxa yokuqukethwe okukhulu kwe-calcium, umlotha usetshenziselwa ukunciphisa i-acidity yenhlabathi.
Izindlela zokusebenzisa
Ama-fertilizer e-potassium amaminerali asebenza kahle kakhulu, ngoba aqala ukwenza ngokushesha ngemva kokufaka umquba. Nciphisa ingxube eyomile ngamanzi ngokusho kwemiyalelo
Umquba womanyolo owomile uqala ikakhulukazi ebusika noma ekuqaleni kwentwasahlobo, lapho kuphela iqhwa. Khona-ke, ngenxa yobuningi bomhlabathi obuphezulu, kancane kancane umanyolo uhlakazeka.
Uma isivuno singaqoqiwe njengoba singathanda, cishe, inhlabathi empofu iyimbangela. Inhlabathi enjalo idinga umquba. Ukuqala ukuwasebenzisa, umgadi wensimu uzothola ngokumangala ukuthi isivuno sande, ngisho nezinambuzane zensimu kanye nensimu sezibe zincane kakhulu. Into eyinhloko ukufunda ngokufanele, ngaphandle kokushiseka kokusebenzisa umquba - owakho kuzo zonke izinhlobo zezitshalo.
