Amazambane ayisitshalo esibalulekile kubalimi emhlabeni wonke, futhi impumelelo yabo incike ezintweni eziningi, kuhlanganise nokuba khona kwemisoco ebalulekile. Nakuba i-nitrogen ne-phosphorus kuvame ukugxila ekuphathweni kwezakhi zomhlabathi, i-potassium ibalulekile ngokulinganayo ekukhiqizeni amazambane. Kulesi sihloko, sizohlola idatha yakamuva mayelana nokusetshenziswa kwe-potassium ekulimeni amazambane, izinzuzo zayo, kanye nemiphumela yokungaphathwa kahle kwe-potassium ekukhiqizeni amazambane kanye nekhwalithi.
I-Potassium iyi-macronutrient yesithathu ebalulekile edingekayo ekukhuleni kwezitshalo, idlala indima ebalulekile ekwakhekeni kwe-tuber yamazambane, isivuno, kanye nekhwalithi. Ngokocwaningo olwenziwa yi-International Potash Institute, amazambane angesinye sezitshalo ezidinga kakhulu i-potassium, adinga kufika ku-300 kg we-potassium ehektheleni ukuze akhule kahle futhi avune.
Izinzuzo zokuphatha i-potassium eyanele ekulimeni amazambane ziningi. I-Potassium isiza ukuthuthukisa ukubekezelela isomiso, ukumelana nezifo, kanye nokubekezelela ingcindezi kumazambane, iwenza akwazi ukumelana nezimo zezulu ezimbi kanye nokuhlaselwa yizinambuzane. Ngaphezu kwalokho, i-potassium idlala indima ebalulekile ekulawuleni ukusebenza kahle kokusetshenziswa kwamanzi, ithuthukise i-photosynthesis, futhi ithuthukise ikhwalithi yezilimo eziyizigaxa zamazambane.
Ngakolunye uhlangothi, ukuphathwa ngendlela efanele kwe-potassium ekulimeni amazambane kungaba nemiphumela emibi kakhulu ekuvunweni naseqophelweni eliphezulu. Amazambane anamazinga aphansi e-potassium asengozini yokuthola izifo ezifana ne-blackleg, uqweqwe, nokulimaza, okuholela ekulahlekelweni kwezitshalo okukhulu. Ngaphezu kwalokho, ukuphathwa kwe-potassium okwanele kungathinta ukwakheka, usayizi, kanye nokufana kwezilimo eziyizigaxa zamazambane, kwehlise inani lazo lemakethe.
Ukugcina amazinga e-potassium esezingeni eliphezulu ekulimeni amazambane, abalimi bangasebenzisa izinqubo ezimbalwa, okuhlanganisa ukuhlola umhlabathi, ukujikelezisa izitshalo, kanye nokuvundisa okufanele. Ngokusebenzisa umanyolo we-potassium ngesikhathi nangesilinganiso esifanele, abalimi bangathuthukisa isivuno samazambane kanye nekhwalithi ngenkathi benciphisa umthelela wemvelo wokusetshenziswa kukamanyolo ngokweqile.
Sengiphetha, i-potassium iyisakhi esibalulekile ekulimeni amazambane, idlala indima ebalulekile ekuvuneni, eqophelweni nasekumelaneni nezifo. Ngokusebenzisa izindlela ezanele zokuphatha i-potassium, abalimi bangathuthukisa ukukhiqizwa kwabo kwamazambane, kube neqhaza ekulimeni okusimeme.
