Potaziyamu Nitrate mu Potaziyamu Feteleza
Olima amayamikira kuthira feteleza ndi KNO₃ makamaka pamene gwero la michere yosungunuka kwambiri, yopanda chloride ikufunika. M'nthaka yotereyi, N zonse zimapezeka nthawi yomweyo kuti zitengedwe ndi zomera monga nitrate, zomwe sizifuna kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda komanso kusintha kwa nthaka. Olima mbewu zamasamba ndi zipatso zamtengo wapatali nthawi zina amakonda kugwiritsa ntchito gwero lazakudya la nitrate pofuna kulimbikitsa zokolola komanso zabwino. Potaziyamu nitrate imakhala ndi gawo lalikulu la K, ndi chiŵerengero cha N mpaka K cha pafupifupi chimodzi kapena zitatu. Mbewu zambiri zimafuna K wochuluka ndipo zimatha kuchotsa K wochuluka kapena wochuluka kuposa N pokolola.
Kuthira kwa KNO₃ m'nthaka kumapangidwa nyengo yolima isanakwane kapena ngati chowonjezera nthawi yakukula. Njira yothirira nthawi zina imapopera masamba pamasamba kuti alimbikitse machitidwe a thupi kapena kuthana ndi kuperewera kwa michere. Kuthira masamba a K pakukula kwa zipatso kumapindulitsa mbewu zina, chifukwa nthawi ya kukula kumeneku nthawi zambiri imagwirizana ndi kuchuluka kwa K panthawi yomwe mizu imachepa komanso kumera kwa michere. Amagwiritsidwanso ntchito kwambiri popanga mbewu zobiriwira komanso chikhalidwe cha hydroponic. atha kugwiritsidwa ntchito ngati feteleza wapansi, kuvala pamwamba, feteleza wa mbeu ndi zipangizo zopangira feteleza pawiri; amagwiritsidwa ntchito kwambiri mu mpunga, tirigu, chimanga, manyuchi, thonje, zipatso, masamba ndi mbewu zina za chakudya ndi mbewu zachuma; amagwiritsidwa ntchito kwambiri mu nthaka yofiira ndi nthaka yachikasu , nthaka ya Brown, nthaka yachikasu ya fluvo-aquic, nthaka yakuda, nthaka ya sinamoni, nthaka yofiirira, nthaka ya albic ndi makhalidwe ena a nthaka.
N ndi K zonse zimafunikira ndi zomera kuti zithandizire kukolola, kupanga mapuloteni, kukana matenda komanso kugwiritsa ntchito madzi moyenera. Choncho, pofuna kuthandizira kukula bwino, alimi nthawi zambiri amagwiritsa ntchito KNO₃ m'nthaka kapena kudzera mu ulimi wothirira panthawi yolima.
Potaziyamu nitrate imagwiritsidwa ntchito makamaka pomwe mawonekedwe ake apadera komanso katundu wake angapereke phindu lapadera kwa alimi. Kupitilira apo, ndiyosavuta kuyigwira ndikuyika, ndipo imagwirizana ndi feteleza ena ambiri, kuphatikiza feteleza wapadera wa mbewu zambiri zamtengo wapatali, komanso zomwe zimagwiritsidwa ntchito pambewu ndi mbewu za fiber.
Kusungunuka kwapang'onopang'ono kwa KNO₃ m'malo otentha kumapangitsa kuti pakhale yankho lokhazikika kuposa feteleza wamba wa K. Komabe, alimi ayenera kusamalira madzi mosamala kuti nitrate asasunthike pansi pa mizu.
