50% Potassium Sulphate Granular (Hōʻano Poʻa) A me (Ke ʻano Pōhaku)
inoa:ʻO Potassium sulfate (US) a i ʻole potassium sulphate (UK), i kapa ʻia ʻo sulphate of potash (SOP), arcanite, a i ʻole archaically potash o ka sulfur, ʻo ia ka mea hoʻohuihui inorganic me ke ʻano K2SO4, he paʻa wai keʻokeʻo. Hoʻohana maʻamau ia i nā mea kanu, e hāʻawi ana i ka potassium a me ka sulfur.
Nā inoa ʻē aʻe:SOP
Hoʻohui pinepine ʻia ka pālima (K) i mea e hoʻomaikaʻi ai i ka hua a me ka maikaʻi o nā mea kanu e ulu ana ma ka lepo i nele i ka lako o kēia meaʻai pono. ʻO ka hapa nui o ka mea momona K mai nā waihona paʻakai kahiko ma ka honua holoʻokoʻa. ʻO ka huaʻōlelo "potash" he huaʻōlelo maʻamau e pili pinepine ana i ka potassium chloride (KCl), akā pili pū kekahi i nā mea kanu K-mea a pau, e like me ka potassium sulfate (K?SO?, i kapa ʻia he sulfate of potash. a i ʻole SOP).
Pono ka potassium no ka hoʻopau ʻana i nā hana koʻikoʻi i loko o nā mea kanu, e like me ka hoʻoulu ʻana i nā hopena enzyme, synthesizing proteins, hoʻokumu i ka starch a me nā kō, a me ka hoʻoponopono ʻana i ke kahe o ka wai i loko o nā cell a me nā lau. ʻO ka manawa pinepine, haʻahaʻa loa ka nui o ka K i ka lepo no ke kākoʻo ʻana i ka ulu olakino olakino.
ʻO ka potassium sulfate kahi kumu maikaʻi o ka meaʻai K no nā mea kanu. ʻAʻole ʻokoʻa ka ʻāpana K o ka K2SO4 mai nā mea kanu potash maʻamau. Eia nō naʻe, hāʻawi ia i kahi kumu waiwai o S, kahi e pono ai ka synthesis protein a me ka hana enzyme. E like me K, hiki ke hemahema loa ʻo S no ka ulu ʻana o ka mea kanu. Eia hou, pono e pale aku i ka hoohui Cl- ma kekahi mau lepo a me na mea kanu. Ma ia mau hihia, hana ʻo K2SO4 i kumu K kūpono loa.
He hoʻokahi hapakolu wale nō ka paʻakai sulfate e like me KCl, no laila, ʻaʻole ia e hoʻoheheʻe maʻamau no ka hoʻohui ʻana ma o ka wai irrigation ke ʻole he pono no S hou.
Loaʻa pinepine ʻia kekahi mau ʻāpana nui. Hoʻopuka nā mea hana i nā ʻāpana liʻiliʻi (ʻoi aku ka liʻiliʻi ma mua o 0.015 mm) no ka hana ʻana i nā mea hoʻonā no ka irrigation a i ʻole nā ʻōpala foliar, no ka mea, ʻoi aku ka wikiwiki o ka hemo ʻana. A ʻike ka poʻe mahiʻai i ka pulupulu lau o K2SO4, he ala kūpono e hoʻopili ai i ka K a me S hou i nā mea kanu, e hoʻohui i nā meaʻai i lawe ʻia mai ka lepo. Eia nō naʻe, hiki ke hōʻino i ka lau inā kiʻekiʻe loa ka ʻike.
