potassium sulfate, eyaziwa ngokuba yi-sulfate ye-potash, isichumiso esisetyenziswa ngokuqhelekileyo esisetyenziselwa ukwandisa isivuno kunye nokuphucula impilo yezityalo. Ingumthombo ocebileyo we-potassium, isondlo esibalulekileyo esidlala indima ebalulekileyo kwiinkqubo ezahlukeneyo zomzimba kwizityalo. Kukho iintlobo ezimbini eziphambili zezichumiso ze-potassium sulfate kwimarike: ibakala legranular kunye nebakala lokunyibilika kwamanzi. Zombini ezi ndidi zineempawu ezikhethekileyo kunye neenzuzo, kwaye ukuqonda ukungafani kwazo kunganceda amafama enze izigqibo ezinolwazi ukwandisa izivuno zezityalo.
Granular potassium sulfate, ezifanaI-50% ye-potassium sulphate granular, sisichumiso esicothayo esibonelela izityalo ngokubonelelwa ngokuzinzileyo kwe potassium kwixesha elide. Olu hlobo lwesichumiso lukholisa ukugalelwa emhlabeni phambi kokutyala okanye ngexesha lamanqanaba okuqala okukhula kwesityalo. Amasuntswana aqhekeka ngokuthe ngcembe, akhuphe i-potassium ion, ethi ifunxwe ziingcambu zezityalo. Le ndlela yokukhululwa kancinane iqinisekisa ukuba izityalo ziyakwazi ukufikelela kwi-potassium xa ziyifuna, ukunciphisa umngcipheko wokuvuza kunye nokuchithwa. Ukongeza, igranular potassium sulfate inceda ekuphuculeni ubume bomhlaba kunye nokuchuma ekuhambeni kwexesha, oko kuyenza ibe lukhetho oluzinzileyo lolawulo lwezityalo ixesha elide.
Ngakolunye uhlangothi, i-potassium sulfate enyibilikayo ngamanzi, sisichumisi esisebenza ngokukhawuleza esinyibilika ngokulula emanzini kwaye silungele ukusetyenziswa kwe-foliar okanye ukunkcenkceshela. Esi sichumisi sinikezela nge-potassium ngokukhawuleza kwizityalo, enenzuzo ngakumbi ngexesha lokukhula okubalulekileyo okanye amaxesha emfuno ephezulu. I-potassium sulfate e-soluble yamanzi nayo ifanelekile ekuxazululeni ukusilela kwe-potassium kwizityalo njengoko inokuthi ifakwe ngokukhawuleza ngamagqabi okanye iingcambu, ngokukhawuleza ukuphucula impilo yezityalo kunye nemveliso.
Zombini izichumisi ze-potassium sulfate zegranular kunye nezinyibilikayo emanzini zineenzuzo zazo xa kufikwa ekwandiseni izivuno zezityalo. Igranular potassium sulfate ifanelekile kulawulo lwexesha elide lokuchuma komhlaba, ibonelela ngomthombo oqhubekayo we potassium kulo lonke ixesha lokukhula. Ngakolunye uhlangothi, i-potassium sulfate ene-soluble yamanzi, inika isisombululo esikhawulezayo nesijoliswe ekuhlangabezaneni neemfuno ze-potassium ngokukhawuleza kunye nokukhuthaza ukukhula ngokukhawuleza kwezityalo kunye nophuhliso.
Kwezinye iimeko, indibaniselwano yeentlobo ezimbini zesichumiso se-potassium sulfate inokuba luncedo ekufumaneni isivuno esisiso sesityalo. Ngokomzekelo, ukusebenzisa i-granular potassium sulfate njengesichumiso esisisiseko ukuseka unikezelo oluzinzileyo lwe-potassium emhlabeni, kunye nokuwuncedisa nge-soluble potassium sulfate ye-soluble yamanzi ngexesha lezigaba ezibalulekileyo zokukhula okanye ngokusekelwe kwiimfuno ezithile zesityalo, kunokunceda ukufezekisa ukulingana phakathi ukuchuma komhlaba okwesibini kunye nexesha elide. kunye nokufumaneka kwezakhamzimba ngokukhawuleza.
Ekugqibeleni, ukhetho phakathi kwesichumiso se-potassium sulfate yegranular kunye nesichumisi se-potassium sulfate esine-soluble yamanzi sixhomekeke kwizinto ezahlukeneyo, ezifana nesityalo esithile esikhulayo, iimeko zomhlaba kunye nenqanaba lokukhula kwezityalo. Abalimi kufuneka bathathele ingqalelo uvavanyo lomhlaba kunye nokubonisana ne-agronomist ukufumanisa uhlobo lwesichumisi kunye nendlela yokufaka efanelekileyo kwiindlela zabo zokulima kunye neemfuno zezityalo.
Ukuqukumbela, isichumiso se-potassium sulfate, nokuba sikwinqanaba legranular okanye inqanaba lokunyibilika kwamanzi, sidlala indima ebalulekileyo ekwandiseni izivuno zezityalo kunye nokukhuthaza impilo yezityalo ngokubanzi. Ukuqonda iiyantlukwano phakathi kwezi zichumisi zimbini kunye noncedo lwazo ngokwahlukeneyo kunganceda amafama enze izigqibo ezizizo ekwandiseni iindlela zawo zokulawula izichumiso kwaye afumane ezona ziphumo zintle entsimini. Ngokukhetha uhlobo olufanelekileyo lwesichumiso se-potassium sulfate nokusisebenzisa kakuhle, abalimi banokuba negalelo kulimo oluzinzileyo nokuqinisekisa ukuveliswa kwezityalo ngempumelelo.
